HTET Exam - Level 1 Prt - Basic Grammar

The correct option is 2:

This sentence requires the use of the Past Perfect tense for the action that happened earlier ("already...") and the Simple Past tense for the later action ("when you arrived"). The Past Perfect tense is formed using the auxiliary verb "had" followed by the past participle of the main verb. The action of starting happened before the action of arriving. Therefore, the phrase "He had already started" correctly conveys that his starting action was completed before your arrival, using "had" and the past participle "started." The word "already" further emphasizes the completion of the action prior to the second past event.

The incorrect option is 1 (has, start): This option uses the Present Perfect tense ("has start" is grammatically incorrect; the correct form would be "has started") combined with the simple past "arrived." Using the Present Perfect is incorrect because the entire sentence refers to two completed actions in the past, making the Past Perfect the necessary tense to establish the sequence of events.

The incorrect option is 3 (had, starts): This option uses the correct auxiliary verb "had" but follows it with the simple present form of the verb "starts." The Past Perfect tense requires the past participle (started), not the simple present form, making this option grammatically incorrect.

The incorrect option is 4 (None): Since Option 2 provides the correct and logical completion of the sentence using the appropriate tense (Past Perfect), this option is incorrect.

The correct option is 2:

The sentence "I wish it were over" is a classic example of the Subjunctive mood in English grammar. The Subjunctive mood is used to express wishes, hypotheses, demands, suggestions, or conditions that are contrary to fact. In this structure, the main clause, "I wish," expresses a desire or regret, and the subordinate clause uses the past tense form of the verb (specifically, "were" instead of the indicative past "was" with the singular subject "it") to indicate that the situation is currently unreal or hypothetical. The use of "were" here, even with a singular subject like 'it,' signals a statement of unreality—the speaker wishes the situation were over, implying that it is not over yet. This specific construction after verbs like 'wish' is the defining characteristic of the Subjunctive mood.

The incorrect option is 1:
The Indicative mood is used for statements of fact, opinions, or questions about reality (e.g., "It is over," or "I am tired"). The sentence "I wish it were over" does not state a fact; it expresses a wish that contradicts the present reality, which immediately rules out the Indicative mood.

The incorrect option is 3:
While the verb form "were" is a past tense form of "to be," classifying the entire sentence based solely on tense is insufficient and misleading. The purpose of using "were" in this context is not to refer to a literal past action, but to signal the unreality or hypothetical nature of the statement, which is a matter of grammatical mood, not just temporal tense.

The incorrect option is 4:
The Present tense is used for current actions or general truths (e.g., "I wish it is over," which is grammatically incorrect for expressing an unreal wish). The verb form used ("were") is clearly not a present tense form, further demonstrating that this option is incorrect.

The correct option is 2:

This question tests your knowledge of the Past Perfect Tense, which is crucial for indicating the sequence of two past actions. When two actions happen in the past, the action that happened first must be expressed in the Past Perfect Tense (had + Past Participle), while the later action is expressed in the Simple Past Tense. In the sentence, "The train ................ (leave) before he reached the station," the train's leaving is the first action, and 'he reached the station' is the second action. The second action, 'reached,' is already in the Simple Past Tense, so the first action must be in the Past Perfect Tense, which is "had left." The conjunction 'before' explicitly signals that the event in the first clause happened prior to the event in the second clause, solidifying the need for the Past Perfect structure.

The incorrect option is 1:
Using the Simple Past Tense, "left," in the first clause would create a grammatically awkward or confusing sentence ("The train left before he reached the station."). While Simple Past can sometimes be used for sequential events, the construction with "before" is universally preferred with the Past Perfect for the action completed first, to clearly distinguish the two past events.

The incorrect option is 3:
"Was leaving" is the Past Continuous Tense, which describes an ongoing action in the past. This tense is typically used to describe an action interrupted by another past action or two simultaneous ongoing actions. It does not clearly convey the meaning that the train's departure was completed before the person arrived, making it logically incorrect in this context.

The incorrect option is 4:
"Had been leaving" is the Past Perfect Continuous Tense. This tense is used to describe an action that started in the past and continued up until another point in the past. It suggests an action of leaving that was continuous and perhaps incomplete, which contradicts the definitive event of the train having already departed before the man reached the station.

The sentence in question is: "It was a clear night and the stars ......." The task is to choose the correct form of the verb to complete the sentence. The correct answer is Option 2: "were twinkling."

1. Explanation for Option 2 ("were twinkling"):

   • The sentence begins with "It was a clear night," which sets the context in the past tense. Therefore, the verb that follows should also be in the past tense to maintain consistency in the sentence structure.
   • "Were twinkling" is the past continuous tense, which is used to describe an action that was ongoing in the past. In this context, it indicates that the stars were continuously twinkling during the clear night.
   • The use of "were" is appropriate because "stars" is a plural noun, and "were" is the correct past tense form of the verb "to be" for plural subjects.

2. Explanation for why the other options are incorrect:

   • Option 1 ("is twinkling"):

     • "Is twinkling" is in the present continuous tense, which is used for actions happening right now. However, the sentence is set in the past ("It was a clear night"), so using the present tense is inconsistent with the rest of the sentence.

   • Option 3 ("has twinkled"):

     • "Has twinkled" is in the present perfect tense, which is used to describe actions that occurred at an unspecified time before now. This tense does not fit the context of the sentence, which is clearly set in the past. Additionally, "has" is used with singular subjects, while "stars" is plural.

   • Option 4 ("are twinkling"):

     • "Are twinkling" is in the present continuous tense, similar to Option 1. It describes an action happening in the present, which contradicts the past tense context established by "It was a clear night."

In conclusion, Option 2 ("were twinkling") is the correct choice because it appropriately uses the past continuous tense to describe the ongoing action of the stars twinkling during a past event, aligning with the past tense context of the sentence.

Explanation:

1. Option 1: "were shopping" - This is the correct answer because it uses the past continuous tense, which is appropriate for describing an action that was ongoing in the past when another action occurred. In the sentence, "Asha and I were shopping on M. G. Road when we saw an old man walking slowly," the action of shopping was in progress when the action of seeing the old man happened. The past continuous tense effectively conveys this simultaneous occurrence of events in the past.

2. Option 2: "have been shopping" - This option is incorrect because it uses the present perfect continuous tense, which is used to describe an action that started in the past and continues into the present or has relevance to the present. The sentence in question is set entirely in the past, with no connection to the present, making this tense inappropriate.

3. Option 3: "had been shopping" - This option is incorrect because it uses the past perfect continuous tense, which is used to describe an action that was ongoing in the past before another past action occurred. However, in the sentence, there is no indication that the shopping was completed before seeing the old man; rather, both actions are presented as happening concurrently. Therefore, the past perfect continuous tense is not suitable here.

4. Option 4: "shopping" - This option is incorrect because it lacks a verb form that indicates tense. Simply using "shopping" does not provide the necessary grammatical structure to convey the ongoing nature of the action in the past. It fails to establish the temporal relationship between the shopping and the act of seeing the old man.

In conclusion, Option 1, "were shopping," is the correct choice because it accurately uses the past continuous tense to describe an action that was ongoing in the past when another action occurred. This tense effectively captures the simultaneous nature of the events described in the sentence.

Option 2 is the correct answer because it uses the present tense verbs "combines" and "takes," which are appropriate for describing a general scientific fact or a process that occurs regularly. In scientific contexts, present tense is often used to describe phenomena that are generally true or repeatable under certain conditions.

1. Explanation for Option 2:

   • "Combines" is the present simple form of the verb "combine," which is used to describe an action that happens regularly or universally. In this sentence, it indicates that the combination of oxygen with carbon and hydrogen in a fuel is a general process that occurs whenever the conditions are right.
   • "Takes" is also in the present simple tense, which is suitable for describing a process that consistently occurs as a result of the combination mentioned. It implies that the chemical reaction is a regular outcome of the combination of these elements.

2. Explanation for why other options are incorrect:

   • Option 1: "Combined; has taken" uses the past tense "combined" and the present perfect tense "has taken." This combination is incorrect because it suggests a completed action in the past, which does not align with the general, ongoing nature of the chemical reaction being described.
   • Option 3: "Combined; takes" uses the past tense "combined" with the present simple "takes." This is inconsistent because it mixes past and present tenses, which is not appropriate for describing a general scientific fact.
   • Option 4: "Combined; is taking" uses the past tense "combined" with the present continuous "is taking." This combination is incorrect because it implies a specific instance of the reaction occurring in the past and continuing into the present, which does not fit the context of a general statement about a chemical process.

In summary, Option 2 correctly uses the present simple tense to describe a general and repeatable scientific process, making it the appropriate choice for completing the sentence.

To complete the sentence "I reached the market when most of the shops _____," the correct verb/tense form is "had closed," which corresponds to Option 3. Here is a detailed explanation justifying why Option 3 is correct and why the other options are incorrect:

1. Explanation for Option 3 ("had closed"):

   • The sentence structure indicates a sequence of events in the past. The use of "had closed" is in the past perfect tense, which is used to describe an action that was completed before another action in the past. In this context, the shops closing is an event that happened before the speaker reached the market. Therefore, "had closed" correctly conveys that the shops were already closed by the time the speaker arrived.

2. Why Option 1 ("has closed") is incorrect:

   • "Has closed" is in the present perfect tense, which is used to describe actions that have occurred at an unspecified time before now. It is not suitable for this sentence because the context clearly involves two past events. The present perfect tense does not appropriately convey the sequence of past actions required here.

3. Why Option 2 ("closed") is incorrect:

   • "Closed" is in the simple past tense, which describes actions that occurred at a specific time in the past. While it might seem appropriate, it does not clearly establish the sequence of events. The sentence requires a tense that indicates the shops were already closed before the speaker reached the market, which the simple past tense does not explicitly convey.

4. Why Option 4 ("has been closed") is incorrect:

   • "Has been closed" is in the present perfect passive voice, which is used to describe actions that have been completed at some point before now, with a focus on the action's result. This tense is inappropriate for the sentence because it does not fit the past narrative context and does not clearly establish the sequence of past events.

In summary, Option 3 ("had closed") is the correct choice because it accurately reflects the sequence of past events, indicating that the shops were already closed when the speaker reached the market.

The sentence "The milk _______ sour." requires a verb form that correctly completes the statement in a grammatically accurate way. Let's analyze each option to understand why Option 1 is the correct choice.

1. Option 1: has turned

   • This option uses the present perfect tense, which is appropriate for describing an action that has occurred at some unspecified time before now and has relevance to the present moment. In this context, "has turned" indicates that the milk became sour at some point in the past and is still sour now. This tense is suitable for expressing a change of state that affects the current condition of the milk, making it the correct choice.

2. Option 2: will be turning

   • This option uses the future continuous tense, which describes an action that will be ongoing at a specific time in the future. However, the sentence does not indicate a future action; it is concerned with the current state of the milk. Therefore, "will be turning" is not appropriate for this context.

3. Option 3: had turn

   • This option is grammatically incorrect because "had turn" is not a valid verb form. The correct past perfect form would be "had turned," but even if it were correctly phrased, the past perfect tense is used to describe an action that was completed before another past action. Since there is no reference to another past action in the sentence, this option is not suitable.

4. Option 4: is turn

   • This option is also grammatically incorrect. The correct present tense form would be "is turning" or "is turned," but neither fits the context of the sentence. "Is turning" would imply an ongoing process, which does not align with the idea of the milk already being sour. "Is turned" would imply a passive voice construction, which is not appropriate here.

In conclusion, Option 1, "has turned," is the correct choice because it accurately describes the milk's change to a sour state in a way that is relevant to the present moment, using the appropriate tense and grammatical structure.

In the given sentence, "I ______ a play by Bernard Shaw," we need to choose the correct form of the verb "read" to complete the sentence appropriately. The correct answer is Option 2: "am reading." Here is the explanation:

1. Why Option 2 is Correct:

   • The sentence "I am reading a play by Bernard Shaw" uses the present continuous tense, which is appropriate for describing an action that is currently in progress. The present continuous tense is formed using the present tense of the verb "to be" (am/is/are) followed by the present participle (verb+ing). In this case, "am" is the correct form of "to be" for the subject "I," and "reading" is the present participle of "read." Therefore, "am reading" correctly indicates that the action of reading is happening right now.

2. Why the Other Options are Incorrect:

   • Option 1: "had reading" - This option is incorrect because "had reading" is not a grammatically correct form in English. The past perfect tense, which uses "had," requires a past participle, not a present participle. The correct form would be "had read," but this does not fit the context of the sentence, which requires a present continuous tense.

   • Option 3: "are reading" - This option is incorrect because "are" is the form of "to be" used with plural subjects or the pronoun "you." Since the subject of the sentence is "I," which is singular, "am" is the correct form to use, not "are."

   • Option 4: "has read" - This option is incorrect because "has read" is in the present perfect tense, which indicates an action that has been completed at some point in the past but is relevant to the present. The sentence requires a form that indicates an ongoing action, not a completed one. Therefore, "am reading" is the appropriate choice for the context.

In conclusion, Option 2, "am reading," is the correct choice because it accurately reflects the ongoing nature of the action described in the sentence.

The correct past tense of the verb "Bring" is "Brought," which is Option 1. Here is a detailed explanation justifying why Option 1 is correct and why the other options are incorrect:

1. Brought (Option 1): "Brought" is the past tense and past participle of the verb "bring." In English, irregular verbs do not follow the standard pattern of adding "-ed" to form the past tense. Instead, they change form entirely, as is the case with "bring" becoming "brought." This is why "brought" is the correct past tense form of "bring."

2. Buy (Option 2): "Buy" is the base form of a different verb, which means to purchase something. It is not related to the verb "bring" and does not represent a past tense form. Therefore, it is incorrect in the context of forming the past tense of "bring."

3. Buying (Option 3): "Buying" is the present participle or gerund form of the verb "buy." It is used to describe an ongoing action or as a noun. Like Option 2, it is related to the verb "buy" and not "bring," making it incorrect for forming the past tense of "bring."

4. Broughted (Option 4): "Broughted" is not a valid word in English. It incorrectly attempts to apply a regular verb past tense pattern to an irregular verb. Since "bring" is an irregular verb, its past tense form is "brought," not "broughted." Therefore, Option 4 is incorrect.

In conclusion, Option 1, "Brought," is the correct past tense of the verb "bring," as it accurately reflects the irregular verb form used in English.

The sentence in question is: "The plane ______ from Delhi at 3.00 clock tomorrow afternoon." The task is to fill in the blank with the correct option, and the correct answer is Option 3: "leaves."

1. Explanation for Option 3 ("leaves"):

   • The use of "leaves" in this context is appropriate because it is in the simple present tense, which is often used to describe scheduled events or timetables. In English, the simple present tense can be used to talk about future events that are fixed or planned, such as the departure of a plane. Since the sentence refers to a specific time ("3.00 clock tomorrow afternoon"), it indicates a scheduled event, making "leaves" the correct choice.

2. Explanation for why the other options are incorrect:

   • Option 1 ("left"): This is in the past tense, which is not suitable for describing a future event. The sentence is clearly about a future event ("tomorrow afternoon"), so using the past tense "left" would be grammatically incorrect.
   • Option 2 ("will have left"): This is in the future perfect tense, which is used to describe an action that will be completed before a certain point in the future. However, the sentence is about a scheduled event, not an action that will be completed before another future event. Therefore, "will have left" does not fit the context.
   • Option 4 ("leaving"): This is a present participle form, which is typically used in continuous tenses or as a gerund. It does not fit the structure of the sentence, which requires a simple present tense verb to indicate a scheduled event.

In conclusion, Option 3 ("leaves") is the correct choice because it appropriately uses the simple present tense to describe a scheduled future event, aligning with the context of the sentence.

The sentence "He is _____ his glasses." requires a verb phrase that correctly completes the sentence in a grammatically correct and contextually appropriate manner. Let's analyze why Option 3, "looking for," is the correct choice and why the other options are incorrect.

1. Explanation for Option 3 ("looking for"):

   • The phrase "looking for" is a present continuous verb phrase. It is used to describe an action that is currently ongoing. In this context, "He is looking for his glasses" means that he is in the process of searching for his glasses at this moment. The use of the present continuous tense is appropriate here because it indicates an action that is happening right now. This makes Option 3 the correct choice for completing the sentence.

2. Explanation for why other options are incorrect:

   • Option 1 ("look for"):

     • "Look for" is in the base form of the verb, which is not suitable for this sentence structure. The sentence requires a present continuous form to indicate an ongoing action. "Look for" does not convey the sense of an action currently taking place, making it grammatically incorrect in this context.

   • Option 2 ("look"):

     • "Look" is a simple present tense verb. It does not fit the sentence structure because it does not convey the ongoing nature of the action. The simple present tense is typically used for habitual actions or general truths, not for actions happening at the moment of speaking.

   • Option 4 ("will look"):

     • "Will look" is in the future tense, indicating an action that will happen at a later time. This does not match the context of the sentence, which requires an action that is happening right now. Therefore, "will look" is not appropriate for completing the sentence.

In summary, Option 3, "looking for," is the correct choice because it accurately describes an ongoing action in the present, fitting both the grammatical structure and the context of the sentence.

The correct answer to fill in the blank in the sentence "If I _____ that you were coming today, I would have met you at the station." is Option 3: "had known."

1. Explanation for Option 3 ("had known"):

   • The sentence is structured as a conditional sentence, specifically a third conditional. Third conditional sentences are used to talk about hypothetical situations in the past that did not happen. They are formed using "if" + past perfect tense in the if-clause, and "would have" + past participle in the main clause.
   • In this sentence, "If I had known" is the correct past perfect form needed to express the hypothetical situation of knowing about the arrival in the past. The main clause "I would have met you at the station" indicates the action that would have occurred if the condition had been met.

2. Explanation for why other options are incorrect:

   • Option 1 ("knew"): This is the simple past tense. It is not suitable for third conditional sentences, which require the past perfect tense in the if-clause. Using "knew" would imply a second conditional, which is used for hypothetical situations in the present or future, not the past.
   • Option 2 ("know"): This is the present tense. It is incorrect for this sentence because it does not match the past hypothetical context required by the third conditional structure.
   • Option 4 ("had knowed"): This is grammatically incorrect because "knowed" is not a valid past participle form of "know." The correct past participle is "known," which is used in Option 3.

In conclusion, Option 3 "had known" correctly fits the grammatical structure of a third conditional sentence, making it the appropriate choice for expressing a hypothetical situation in the past.

Option 4, "have been playing," is the correct answer because it uses the present perfect continuous tense. This tense is used to describe an action that started in the past and is still continuing in the present. The phrase "since four O'clock" indicates a specific starting point in the past, and the implied meaning is that they are still playing. Therefore, the present perfect continuous tense is the most appropriate choice.

Here's why the other options are incorrect:

• Option 1: have played: This uses the present perfect tense. While it indicates an action completed in the past with relevance to the present, it doesn't emphasize the duration of the action. "They have played since four O'clock" sounds awkward and doesn't convey the continuous nature of the activity. It implies they finished playing at some point after four o'clock, which contradicts the intended meaning.

• Option 2: will play: This uses the future simple tense. It indicates an action that will happen in the future. Since the sentence includes "since four O'clock," which refers to a past time, the future tense is grammatically incorrect and illogical.

• Option 3: play: This uses the simple present tense. The simple present tense is used for habitual actions or general truths. It doesn't fit the context of an action that started at a specific time in the past and is ongoing. "They play since four O'clock" is grammatically incorrect and doesn't make sense.

Option 1, "Began, Begun," is the correct answer because it accurately represents the past tense and past participle forms of the verb "Begin."

• "Began" is the simple past tense form of "Begin." For example, "The meeting began at 9 am."

• "Begun" is the past participle form of "Begin." It is used with auxiliary verbs like "have," "has," or "had" to form perfect tenses. For example, "The project has begun."

Now, let's examine why the other options are incorrect:

• Option 2: Begun, Begun: While "Begun" is the past participle, it is not the past tense. The past tense is "Began." Therefore, this option is incorrect.

• Option 3: Begin, Began: "Begin" is the base form of the verb, not the past tense or past participle. "Began" is the past tense, but the order is incorrect, and "Begin" is not the past participle.

• Option 4: Begun, Began: "Begun" is the past participle, but "Began" is the past tense. The order is incorrect, and "Began" is not the past participle.

Therefore, only Option 1 correctly identifies "Began" as the past tense and "Begun" as the past participle of the verb "Begin."

The sentence in question is: "I was tired because I ______ for a long time." The task is to fill in the blank with the correct verb form. The correct answer is Option 3: "had been working."

1. Explanation for Option 3 (Correct Answer):

   • The sentence is structured in the past tense, as indicated by "I was tired." This suggests that the action causing the tiredness also occurred in the past. The phrase "had been working" is in the past perfect continuous tense, which is used to describe an action that started in the past and continued up to a certain point in the past. In this context, "had been working" appropriately indicates that the speaker was engaged in work for a long duration before the point in time when they felt tired. This tense effectively links the past action of working with the past state of being tired, making it the correct choice.

2. Explanation for why the other options are incorrect:

   • Option 1: "was working"

     • "Was working" is in the past continuous tense, which describes an ongoing action in the past. However, it does not convey the sense of an action that was completed before another past action or state (being tired). It lacks the aspect of duration leading up to the point of tiredness, which is crucial in this context.

   • Option 2: "have been working"

     • "Have been working" is in the present perfect continuous tense, which is used for actions that started in the past and continue into the present or have relevance to the present. This tense is inappropriate here because the sentence is entirely set in the past. The use of "have been working" would incorrectly suggest that the working continued up to the present, which contradicts the past context of the sentence.

   • Option 4: "am working"

     • "Am working" is in the present continuous tense, indicating an action that is currently ongoing. This tense is unsuitable for the sentence because it shifts the timeframe to the present, whereas the sentence clearly describes a past situation. Using "am working" would imply that the speaker is currently working, which does not align with the past context of feeling tired.

In summary, Option 3, "had been working," is the correct choice because it accurately reflects an action that occurred over a period in the past and was completed before the speaker felt tired. The other options fail to convey this past relationship appropriately.

Option 2, "Having Read," is the correct choice to fill in the blank because it accurately conveys the sequence of events in the sentence. The phrase "Having Read" is a perfect participle, which is used to indicate that one action was completed before another action took place. In this context, it means that the action of reading the book was completed before the action of returning it to the library. This sequence is logically consistent with the intended meaning of the sentence.

Now, let's examine why the other options are incorrect:

1. Reading: This option suggests that the action of reading and returning the book happened simultaneously, which does not logically fit the context of the sentence. The sentence implies that the book was read completely before it was returned, not during the act of returning.

2. Will Read: This option indicates a future action, which does not align with the past tense context of the sentence. The sentence clearly describes a sequence of past events, so using a future tense form is inappropriate.

3. Read: While this option is in the past tense, it does not convey the completion of the action before the next action took place. It lacks the perfect aspect that "Having Read" provides, which is necessary to show that the reading was completed prior to returning the book.

In summary, "Having Read" is the only option that correctly indicates the completion of one action before another, making it the appropriate choice for the sentence.

The correct answer is Option 1: "have lost."

1. Explanation for Option 1: "have lost"

   • The sentence "I (lose) my pen, please help me find it" implies that the action of losing the pen has relevance to the present moment. The present perfect tense, which is formed using "have" + past participle (lost), is used to describe actions that have occurred at some indefinite time in the past and are relevant to the present. In this context, "have lost" indicates that the pen was lost at some point before now, and the speaker is currently experiencing the consequence of that action, which is the need to find the pen.

2. Explanation for why the other options are incorrect:

   • Option 2: "did lost"

     • This option is grammatically incorrect. The past simple tense is formed using "did" + base form of the verb, so it should be "did lose" if it were to be correct. However, even with the correct form, the past simple tense would not be appropriate here because it does not convey the ongoing relevance of the action to the present moment.

   • Option 3: "will lose"

     • This option uses the future simple tense, which is used to describe actions that will happen in the future. It is not suitable for this sentence because the action of losing the pen has already occurred, and the speaker is dealing with the current consequence of that past action.

   • Option 4: "loose"

     • "Loose" is an adjective meaning not tight or free, and it is not a verb form. Therefore, it cannot be used to describe the action of losing something. This option is incorrect because it does not fit the grammatical structure required for the sentence.

In conclusion, Option 1 "have lost" is the correct choice because it accurately uses the present perfect tense to convey that the action of losing the pen has occurred in the past and is relevant to the present situation.

The correct past form of the verb 'Choose' is 'Chose', which is Option 2. Here is a detailed explanation justifying why Option 2 is correct and why the other options are incorrect:

1. Explanation for Option 2 (Chose):

   • The verb 'choose' is an irregular verb, which means it does not follow the regular pattern of adding -ed to form its past tense. Instead, it changes its form entirely. The past tense of 'choose' is 'chose'. This is a well-established rule in English grammar for irregular verbs. Therefore, 'chose' is the correct past form of 'choose'.

2. Explanation for why other options are incorrect:

   • Option 1 (Chosen): 'Chosen' is not the past tense of 'choose'; it is the past participle form. Past participles are used in perfect tenses and passive voice, not as simple past tense forms. For example, in the present perfect tense, you would say, "I have chosen."

   • Option 3 (Choosed): 'Choosed' is incorrect because 'choose' is an irregular verb and does not take the regular -ed ending to form its past tense. Regular verbs form their past tense by adding -ed, but 'choose' does not follow this pattern.

   • Option 4 (Choose): 'Choose' is the base form of the verb and is used in the present tense. It does not represent the past tense, which is required in this context.

In conclusion, Option 2, 'Chose', is the correct past form of the verb 'choose', as it accurately reflects the irregular verb conjugation rules in English.

The correct verb form is "left" (Option 3) because the sentence describes an action that was completed in the past. The word "yesterday" is a clear indicator of past tense.

Here's why the other options are incorrect:

• Option 1: leave: This is the base form of the verb and is used for present tense actions or general truths. It doesn't fit the context of an action completed "yesterday."

• Option 2: will leave: This indicates a future action. Since the sentence specifies "yesterday," a future tense verb is inappropriate.

• Option 4: will be leaving: This is the future continuous tense, indicating an action that will be in progress at some point in the future. Again, "yesterday" makes this tense incorrect.

Therefore, "left" is the only option that correctly reflects the past tense action indicated by "yesterday," making Option 3 the correct answer.
