Answer & Explanation
Question 263
Choose the appropriate meaning of the modal in the following sentence :
"It must be hard to work 60 hours a week."
Choose an answer to reveal your result and explanation.
Answer & Explanation
The correct answer is Option 2: probability. Here's why:
-
Why Option 2 (probability) is correct: In the sentence "It must be hard to work 60 hours a week," the modal verb "must" expresses a strong degree of belief or logical deduction about something. The speaker doesn't know for certain that it is hard, but based on their understanding of work and the demands of a 60-hour work week, they are making a highly probable conclusion. "Must" indicates a high likelihood or strong inference, making probability the most fitting meaning in this context. The speaker is inferring the difficulty based on the information available to them.
-
Why Option 1 (necessity) is incorrect: "Necessity" implies that something is required or essential. The sentence doesn't suggest that working 60 hours a week is required or necessary; it's commenting on the likely difficulty of doing so. "Must" would indicate necessity if the sentence were something like, "You must submit your report by Friday."
-
Why Option 3 (possibility) is incorrect: "Possibility" suggests that something could happen or might be true. While it's possible that working 60 hours a week is hard, "must" conveys a much stronger sense of conviction than mere possibility. "Might," "could," or "may" would be more appropriate if the sentence were expressing possibility.
-
Why Option 4 (intention) is incorrect: "Intention" refers to a plan or purpose. The sentence doesn't express any plan or intention related to working 60 hours a week. The speaker isn't intending to do anything; they are simply making an observation about the likely difficulty of a situation.
Question 264
Identify the correct passive form of the sentence :
"It is said that they know it."
Choose an answer to reveal your result and explanation.
Answer & Explanation
Option 3, "Everybody says that it is known to them," is the most appropriate passive-like transformation of the original sentence, "It is said that they know it," because it effectively conveys the same meaning while shifting the focus. Here's why:
-
Meaning Preservation: The original sentence implies a general consensus or widespread belief. Option 3 captures this by using "Everybody says," which is a more active way of expressing the same idea. The phrase "it is known to them" maintains the core information that 'they' possess the knowledge.
-
Passive Voice Implication: While not a direct passive voice construction of the entire original sentence, Option 3 effectively transforms the implied active voice portion. The original sentence, "It is said that they know it," implies someone is saying it. Option 3 makes this explicit with "Everybody says." The second part, "that it is known to them," is a passive construction of "they know it."
Now, let's examine why the other options are incorrect:
-
Option 1: It is being said that they known it. This option is grammatically incorrect. "Known" is the past participle and should be used with "have" or "has" to form the present perfect tense. Also, "is being said" is typically used for ongoing actions, which doesn't fit the general statement of the original sentence.
-
Option 2: They said it that it was known by them. This option changes the meaning and structure significantly. It implies a specific instance of them saying something, rather than a general understanding. The phrasing is also awkward and unnatural.
-
Option 4: That they know it has been said by them. This option is grammatically correct but alters the emphasis and meaning. It focuses on the act of saying rather than the knowledge itself. It also implies a specific group ("them") is responsible for the statement, which isn't the implication of the original sentence. The original sentence implies a more general, unspecified source of the statement.
In conclusion, Option 3, "Everybody says that it is known to them," is the best choice because it maintains the original sentence's meaning of a general belief and uses a construction that effectively conveys the passive-like sense of the original statement. The other options either change the meaning, are grammatically incorrect, or shift the emphasis in a way that doesn't align with the original sentence.
Question 265
Identify the adverb clause in the following sentence :
"Whoever wishes can send whomever they like whatever they like whenever they like."
Choose an answer to reveal your result and explanation.
Answer & Explanation
The adverb clause in the sentence "Whoever wishes can send whomever they like whatever they like whenever they like" is "Whenever they like." Here's why:
-
Why Option 4 ("Whenever they like") is correct: An adverb clause modifies a verb, adjective, or another adverb, and it answers questions like when, where, why, how, to what extent, or under what condition. The clause "whenever they like" modifies the verb "send" by specifying when the sending can occur. It indicates the time or occasion for the action. Therefore, it functions as an adverb clause of time.
-
Why Option 1 ("Whoever wishes") is incorrect: "Whoever wishes" functions as a noun clause. It acts as the subject of the verb "can send." Noun clauses function as nouns, taking the place of subjects, objects, or complements. It doesn't modify a verb, adjective, or adverb; it's the subject performing the action.
-
Why Option 2 ("Whomever they like") is incorrect: "Whomever they like" functions as a noun clause. It acts as the direct object of the verb "send." It specifies who is being sent. Like Option 1, it functions as a noun, not an adverb.
-
Why Option 3 ("Whatever they like") is incorrect: "Whatever they like" also functions as a noun clause. It acts as the direct object of the verb "send." It specifies what is being sent. Again, it functions as a noun, not an adverb.
Question 266
Which part of the following sentence is grammatically incorrect ?
The facts in that complex case is questionable.
Choose an answer to reveal your result and explanation.
Answer & Explanation
The grammatically incorrect part of the sentence is "is".
Explanation:
The subject of the sentence is "The facts". "Facts" is a plural noun. Therefore, the verb must agree with the plural subject. The singular verb "is" does not agree with the plural subject "facts". The correct verb to use would be "are".
Why the other options are incorrect:
-
Option 1: "the": The definite article "the" is used correctly to specify which facts are being referred to (the facts in that complex case). There is no grammatical error in its usage.
-
Option 2: "in": The preposition "in" is used correctly to indicate the location or context of the facts (the facts in that complex case). It establishes the relationship between the facts and the case.
-
Option 3: "that": The demonstrative adjective "that" is used correctly to specify which complex case is being referred to. It correctly modifies the noun "case".
Question 267
Which of the following is a simple sentence ?
Choose an answer to reveal your result and explanation.
Answer & Explanation
Option 2, "He gave a sterling performance in his debut itself," is a simple sentence because it contains only one independent clause. An independent clause has a subject ("He") and a verb ("gave") and expresses a complete thought. There are no coordinating conjunctions, subordinating conjunctions, or relative pronouns that would link it to another clause.
Here's why the other options are incorrect:
-
Option 1: "I was surprised when I heard his dismissal." This is a complex sentence. It contains one independent clause ("I was surprised") and one dependent clause ("when I heard his dismissal"). The dependent clause is introduced by the subordinating conjunction "when."
-
Option 3: "As I was busy, I could not meet them." This is also a complex sentence. It has one independent clause ("I could not meet them") and one dependent clause ("As I was busy"). The dependent clause is introduced by the subordinating conjunction "As."
-
Option 4: "The doctor took all precautions still his condition deteriorated." This is a compound sentence. It contains two independent clauses ("The doctor took all precautions" and "his condition deteriorated") joined by the coordinating conjunction "still" (used here as a conjunctive adverb).
Question 268
Which of the following sentences is not in the passive voice ?
Choose an answer to reveal your result and explanation.
Answer & Explanation
Option 4, "Someone's offered me a better job," is not in the passive voice. Here's why:
-
Active vs. Passive Voice: The active voice emphasizes the subject performing the action (e.g., "The dog chased the ball"). The passive voice emphasizes the object receiving the action (e.g., "The ball was chased by the dog"). In the passive voice, the verb typically includes a form of "to be" (is, was, were, are, been, being) followed by the past participle of the main verb.
-
Analyzing Option 4: In "Someone's offered me a better job," the subject is "Someone," and the verb is "offered." "Someone" is performing the action of offering. There is no form of "to be" preceding the past participle "offered." Therefore, it's in the active voice.
Now, let's explain why the other options are incorrect:
-
Option 1: "My car was stolen last night." This sentence is in the passive voice. The subject "My car" is receiving the action of being stolen. The verb "was stolen" includes the form of "to be" ("was") followed by the past participle "stolen."
-
Option 2: "Spanish is spoken in many Latin American Countries." This sentence is in the passive voice. The subject "Spanish" is receiving the action of being spoken. The verb "is spoken" includes the form of "to be" ("is") followed by the past participle "spoken."
-
Option 3: "My house is being painted." This sentence is in the passive voice. The subject "My house" is receiving the action of being painted. The verb "is being painted" includes the form of "to be" ("is being") followed by the past participle "painted."
Question 269
I must finish the work today.'
The underlined modal auxiliary shows :
Choose an answer to reveal your result and explanation.
Answer & Explanation
The underlined modal auxiliary "must" in the sentence "I must finish the work today" shows necessity.
Here's why:
-
Why Option 2 (necessity) is correct: "Must" expresses that it is necessary for the speaker to finish the work today. There is a need or requirement to complete the task. The sentence implies that there will be negative consequences or the goal will not be achieved if the work is not finished. It highlights the essential nature of completing the work.
-
Why Option 1 (compulsion) is incorrect: While "must" can sometimes imply compulsion, in this context, it's more about the inherent need to finish the work. Compulsion often suggests an external force or someone else forcing the action. The sentence focuses on the speaker's internal understanding of the need to complete the work.
-
Why Option 3 (likelihood) is incorrect: "Must" does not express probability or the chance of something happening. Likelihood is associated with modal auxiliaries like "might," "may," or "could." "Must" indicates a certainty of action required, not a possibility.
-
Why Option 4 (obligation) is incorrect: While necessity and obligation are closely related, obligation often implies a duty or responsibility, often imposed by an external rule or authority. While finishing the work could be an obligation, the sentence emphasizes the need to finish it, regardless of whether it's a formal obligation. The focus is on the essential nature of the task completion.
Question 270
Which of the following is in the passive voice ?
Choose an answer to reveal your result and explanation.
Answer & Explanation
The money was stolen from the bank.
Explanation:
Option 1, "The money was stolen from the bank," is in the passive voice because the subject ("The money") is receiving the action ("was stolen"). The focus is on what happened to the money, not on who performed the action of stealing. The verb "was stolen" is a form of the verb "to be" (was) combined with the past participle of the verb "steal" (stolen), which is a key characteristic of passive voice constructions. The agent performing the action (the thief) is not explicitly mentioned, further indicating the passive nature of the sentence.
Why the other options are incorrect:
-
Option 2: My friend Tom has a nice house. This sentence is in the active voice. The subject ("My friend Tom") is performing the action ("has"). The verb "has" is a simple present tense verb, and the sentence structure follows the subject-verb-object pattern typical of active voice.
-
Option 3: The police arrested the burglar. This sentence is also in the active voice. The subject ("The police") is performing the action ("arrested"). The verb "arrested" is in the past tense, and the sentence clearly shows who performed the action.
-
Option 4: Doctors help people who are sick. This sentence is in the active voice. The subject ("Doctors") is performing the action ("help"). The verb "help" is in the present tense, and the sentence structure indicates a direct action performed by the subject.
Question 271
Which of the following sentences is grammatically incorrect ?
Choose an answer to reveal your result and explanation.
Answer & Explanation
Option 1 is grammatically incorrect because when "each" is used before singular nouns connected by "and," the verb should be singular. The correct sentence would be: "Each boy and each girl was punished." The use of "were" indicates a plural subject, which contradicts the singular emphasis created by "each."
Here's why the other options are grammatically correct:
-
Option 2: Statistics is a difficult subject. While "statistics" can sometimes be plural (referring to data), in this context, it refers to the field of study of statistics, which is treated as a singular subject. Therefore, the singular verb "is" is correct.
-
Option 3: The captain of the players has not come yet. The subject of the sentence is "the captain," which is singular. The phrase "of the players" is a prepositional phrase modifying "captain." The singular verb "has" agrees with the singular subject.
-
Option 4: A great number of people have come here. "A great number of" is followed by a plural noun ("people") and takes a plural verb ("have"). This construction is grammatically correct.
Question 272
I would rather read than talk.'
The underlined modal auxiliary shows :
Choose an answer to reveal your result and explanation.
Answer & Explanation
The underlined modal auxiliary "would rather" in the sentence "I would rather read than talk" shows preference because:
- "Would rather" is a specific idiomatic expression used to indicate a preference. It directly expresses that the speaker favors one action (reading) over another (talking). The structure "would rather + verb + than + verb" is a standard way to express choosing one thing over another.
Now, let's explain why the other options are incorrect:
-
1. Probability: Modal auxiliaries expressing probability include words like "might," "may," "could," and "should." "Would rather" doesn't suggest the likelihood of an event happening; it expresses a choice. The sentence isn't about how likely the speaker is to read or talk, but about which activity they prefer.
-
2. Strong desire: While preference can imply a desire, "would rather" doesn't necessarily convey a strong desire. It simply indicates a choice between two options. Modal auxiliaries that express strong desire include "must," "have to," or emphatic uses of "will." The sentence doesn't suggest the speaker is desperate to read, only that they prefer it to talking.
-
4. Determination: Modal auxiliaries expressing determination include "will," "shall," and "must." "Would rather" doesn't convey a sense of resolve or firm intention. The sentence doesn't imply the speaker is determined to read regardless of circumstances; it simply states their preference.
Therefore, the only option that accurately describes the function of "would rather" in the given sentence is preference.
Question 273
Choose the correct option to fill in the blanks in the following question :
John talks and talks and talks and yet he never _____ anything.
Choose an answer to reveal your result and explanation.
Answer & Explanation
Here's the explanation:
Option 1, "says," is the correct choice because it fits the context of the sentence most naturally. The sentence describes someone who talks a lot but doesn't actually communicate anything of substance. "Says" implies the act of uttering words, which aligns with the idea of someone talking incessantly without conveying meaningful information. He talks and talks, but he never says anything of value or importance.
Here's why the other options are incorrect:
-
Option 2: tells: "Tells" implies conveying information or a story. If John never tells anything, it suggests he doesn't share information, which isn't necessarily implied by simply talking a lot. Someone can talk a lot without telling a story or conveying specific information.
-
Option 3: informs: "Informs" means to give someone facts or information. If John never informs anything, it means he doesn't provide facts or knowledge. While this could be true, "says" is a broader and more fitting term for someone who talks a lot without substance.
-
Option 4: voice: "Voice" is a noun, not a verb, and doesn't fit grammatically in the blank. You can't "never voice anything" in this context. You might "voice an opinion," but that's different from the general act of talking.
Question 274
Which of the following sentences has a noun clause ?
Choose an answer to reveal your result and explanation.
Answer & Explanation
Option 3, "That you have come pleases me," is the correct answer because it contains a noun clause.
Here's why:
-
What is a Noun Clause? A noun clause is a dependent clause that functions as a noun. This means it can take the place of a subject, object, complement, or appositive in a sentence.
-
Analyzing Option 3: In the sentence "That you have come pleases me," the clause "That you have come" acts as the subject of the verb "pleases." The entire clause functions as a noun because it's performing the role of the subject. We can replace the entire clause with a single noun, like "Your arrival pleases me," to illustrate this point.
Now, let's examine why the other options are incorrect:
-
Option 1: "Because you have done this I shall punish you." This sentence contains an adverb clause introduced by the subordinating conjunction "because." The clause "Because you have done this" modifies the verb "shall punish" by providing a reason. It answers the question "Why shall I punish you?" Adverb clauses modify verbs, adjectives, or adverbs, not nouns.
-
Option 2: "They went where living was cheaper." This sentence contains an adverb clause introduced by the subordinating conjunction "where." The clause "where living was cheaper" modifies the verb "went" by indicating the place. It answers the question "Where did they go?" Adverb clauses modify verbs, adjectives, or adverbs, not nouns.
-
Option 4: "If you do not hurry you will miss the train." This sentence contains an adverb clause introduced by the subordinating conjunction "if." The clause "If you do not hurry" modifies the verb "will miss" by providing a condition. It answers the question "Under what condition will you miss the train?" Adverb clauses modify verbs, adjectives, or adverbs, not nouns.
Therefore, only Option 3 contains a clause that functions as a noun, making it the correct answer.
Question 275
Fill in the blank with the correct option :
This house _____ to me.
Choose an answer to reveal your result and explanation.
Answer & Explanation
The correct answer is Option 1: belongs.
Explanation:
-
Why Option 1 (belongs) is correct: The verb "belong" describes a state of ownership or possession. It's a stative verb, meaning it describes a state rather than an action. Stative verbs are generally used in the simple present tense to describe a current state or fact. "This house belongs to me" is a simple, direct statement of ownership, expressing a current and ongoing state.
-
Why Option 2 (is belonging) is incorrect: "Is belonging" is the present continuous tense. Stative verbs like "belong" are generally not used in continuous tenses. Using "is belonging" would be grammatically incorrect and sound unnatural. While there might be rare, highly specific contexts where a stative verb is used in a continuous tense for emphasis or a temporary situation, ownership is not typically one of them. The sentence implies a permanent or long-term state of ownership, making the continuous tense inappropriate.
-
Why Option 3 (has been belonging) is incorrect: "Has been belonging" is the present perfect continuous tense. This tense is used to describe an action that started in the past and is still continuing. As with the present continuous, stative verbs like "belong" are generally not used in the present perfect continuous tense. It would imply that the house started belonging to me at some point in the past and is still in the process of belonging to me, which doesn't make logical sense in the context of ownership.
-
Why Option 4 (had belonging) is incorrect: "Had belonging" is grammatically incorrect. The past perfect tense requires a past participle form of the verb, which would be "belonged." Even if it were "had belonged," it would still be incorrect. The past perfect tense describes an action completed before another action in the past. It doesn't fit the context of a simple statement of current ownership. The sentence needs to express a present state, not a past action completed before another past action.
Question 276
Which of the following sentence is grammatically correct ?
Choose an answer to reveal your result and explanation.
Answer & Explanation
Option 2, "The rise and fall of the tide is due to lunar influence," is grammatically correct because the subject "the rise and fall" is considered a singular concept referring to the single phenomenon of the tide's movement. Therefore, the singular verb "is" agrees with the singular subject.
Here's why the other options are incorrect:
-
Option 1: The state of his affairs were such as to cause anxiety to his creditors. The subject of the sentence is "the state," which is singular. Therefore, the verb should be "was," not "were." The correct sentence would be: "The state of his affairs was such as to cause anxiety to his creditors."
-
Option 3: The Chairman, with the directors, are to be present. The phrase "with the directors" is a prepositional phrase that modifies the subject "The Chairman." The subject is still "The Chairman," which is singular. Therefore, the verb should be "is," not "are." The correct sentence would be: "The Chairman, with the directors, is to be present."
-
Option 4: Sanskrit, as well as Arabic, were taught there. Similar to option 3, the phrase "as well as Arabic" is an added phrase and doesn't change the subject. The subject is "Sanskrit," which is singular. Therefore, the verb should be "was," not "were." The correct sentence would be: "Sanskrit, as well as Arabic, was taught there."
Question 277
Identify the correct 'passive construction' of the following sentence :
They laughed at his warnings and objected to all his proposals.
Choose an answer to reveal your result and explanation.
Answer & Explanation
His warnings were laughed at and all his proposals were objected to.
Explanation:
Option 3, "His warnings were laughed at and all his proposals were objected to," is the correct passive construction because it transforms the original active voice sentence into a passive voice sentence while maintaining the original meaning. Here's why:
-
Passive Voice Formation: The passive voice is formed using a form of the verb "to be" (in this case, "were") followed by the past participle of the main verb (e.g., "laughed," "objected"). The subject of the active sentence ("They") becomes the agent (often omitted or placed in a "by" phrase, which is not necessary here for a grammatically correct passive construction). The object of the active sentence ("his warnings" and "all his proposals") becomes the subject of the passive sentence.
-
Correct Transformation: The original sentence has two clauses: "They laughed at his warnings" and "They objected to all his proposals." In the passive construction, these become:
- "His warnings were laughed at" (passive of "They laughed at his warnings")
- "All his proposals were objected to" (passive of "They objected to all his proposals")
-
Preservation of Meaning: The passive construction accurately conveys the same information as the active sentence. The focus shifts from the actors ("They") to the actions performed on "his warnings" and "all his proposals."
Why the other options are incorrect:
-
Option 1: They laughed and objected to his warnings and proposals respectively. This option is in the active voice, not the passive voice. It simply rephrases the original sentence without changing the voice. "Respectively" is used correctly, but the sentence doesn't address the question's requirement for a passive construction.
-
Option 2: At his warnings, they laughed and to all his proposals, they objected. This option is also in the active voice. It rearranges the sentence structure but does not transform it into the passive voice. It's simply a stylistic variation of the active sentence.
-
Option 4: At his warnings, they were laughing and to all his proposals, they were objecting. This option uses the past continuous tense ("were laughing," "were objecting"), which changes the meaning and tense of the original sentence. The original sentence implies a completed action, while this option suggests an ongoing action. Furthermore, it remains in the active voice, not the passive voice.
Question 278
Which of the following sentences is in the active voice ?
Choose an answer to reveal your result and explanation.
Answer & Explanation
Option 4, "I remember my father taking me to the zoo," is in the active voice because the subject ("I") performs the action ("remember"). The object of the verb "remember" is the gerund phrase "my father taking me to the zoo," where "my father" is actively performing the action of "taking." The sentence clearly shows the subject acting upon an object.
Here's why the other options are incorrect:
-
Option 1: Wolves have been seen in the streets. This sentence is in the passive voice. The subject ("Wolves") is receiving the action ("seen"). The agent performing the action is not explicitly stated, or is implied. The structure "have been seen" is a clear indicator of the passive voice.
-
Option 2: The injured player was being carried off the field. This sentence is also in the passive voice. The subject ("The injured player") is receiving the action ("was being carried"). Again, the agent performing the action is not explicitly stated. The structure "was being carried" is a clear indicator of the passive voice.
-
Option 3: The old newspapers were thrown away. This sentence is in the passive voice. The subject ("The old newspapers") is receiving the action ("were thrown"). The agent performing the action is not explicitly stated. The structure "were thrown" is a clear indicator of the passive voice.
Question 279
Which is the odd one out ? (Sentence pattern)
Choose an answer to reveal your result and explanation.
Answer & Explanation
Option 3 is the odd one out because it's the only sentence that uses a gerund phrase as its object. Let's break it down:
- Option 3: "I can't stand travelling in the rush-hour." Here, "travelling in the rush-hour" is a gerund phrase acting as the object of the verb "stand." A gerund is a verb form ending in "-ing" that functions as a noun.
Now, let's examine why the other options are incorrect:
-
Option 1: "They did very little work that day." The object of the verb "did" is the noun "work." It's a simple noun, not a gerund or gerund phrase.
-
Option 2: "We shall make an announcement tomorrow." The object of the verb "make" is the noun "announcement." Again, a simple noun, not a gerund or gerund phrase.
-
Option 4: "The company has bought several new aircraft." The object of the verb "bought" is the noun "aircraft." This is also a simple noun, not a gerund or gerund phrase.
Therefore, only Option 3 contains a gerund phrase as its object, making it the odd one out in terms of sentence pattern.
Question 280
Identify the sentence/s with the Noun Clause from the given sentences :
(a) Who will be selected for the post is not certain.
(b) He came to tell me that the school was closed.
(c) The gift that Ravi brought was the best.
(d) We went into the room where everyone had gathered.
Choose an answer to reveal your result and explanation.
Answer & Explanation
Here's the explanation supporting Option 2 as the correct answer:
Why Option 2 (Sentences (a) and (b)) is Correct:
A noun clause functions as a noun within a sentence. It can act as a subject, object, complement, or appositive.
-
(a) Who will be selected for the post is not certain. In this sentence, the clause "Who will be selected for the post" acts as the subject of the verb "is." The entire clause functions as a noun, representing the unknown entity being discussed. Therefore, it's a noun clause.
-
(b) He came to tell me that the school was closed. In this sentence, the clause "that the school was closed" acts as the direct object of the verb "tell." He came to tell something, and that something is the noun clause "that the school was closed."
Why the other options are incorrect:
-
Option 1 (Only sentence (a)): While sentence (a) does contain a noun clause, sentence (b) also contains a noun clause. Therefore, this option is incomplete and incorrect.
-
Option 3 (Sentences (b) and (c)): Sentence (b) contains a noun clause, as explained above. However, sentence (c) contains an adjective clause (also known as a relative clause). The clause "that Ravi brought" modifies the noun "gift." Adjective clauses modify nouns, while noun clauses function as nouns themselves. Therefore, sentence (c) does not contain a noun clause.
-
Option 4 (Sentences (c) and (d)): As explained above, sentence (c) contains an adjective clause, not a noun clause. Sentence (d), "We went into the room where everyone had gathered," contains an adverbial clause of place. The clause "where everyone had gathered" modifies the verb "went," indicating where they went. Adverbial clauses modify verbs, adjectives, or adverbs, not nouns. Therefore, sentence (d) does not contain a noun clause.
In conclusion, only sentences (a) and (b) contain noun clauses, making Option 2 the correct answer.
