Question

Fill in the blanks with the correct forms of the Verb :
 What ____ you ____ yesterday ... with this knife?

Accepted Answer

Explanation:

1. **Correct Answer: Option 3 - "did, do"**

The sentence in question is: "What ____ you ____ yesterday ... with this knife?" To fill in the blanks correctly, we need to consider the tense and structure of the sentence. The word "yesterday" indicates that the action took place in the past. Therefore, the first blank requires a past tense auxiliary verb, which is "did." The second blank requires the base form of the main verb, which is "do," because when using "did" as an auxiliary verb in questions, the main verb remains in its base form. Thus, the correct sentence is: "What did you do yesterday ... with this knife?"

2. **Why Other Options Are Incorrect:**

- **Option 1: "do, did"**
     - This option is incorrect because "do" is present tense, which does not match the past tense context indicated by "yesterday." Additionally, "did" as the main verb is not appropriate here, as the structure requires the base form of the verb after "did."

- **Option 2: "do, do"**
     - This option is incorrect because both "do" verbs are in the present tense, which contradicts the past tense context provided by "yesterday." The sentence requires a past tense auxiliary verb followed by the base form of the main verb.

- **Option 4: "did, did"**
     - This option is incorrect because while "did" is correctly used as the past tense auxiliary verb, the second "did" is not in the base form. After using "did" as an auxiliary verb, the main verb should be in its base form, which is "do."

In conclusion, Option 3 is the only choice that correctly uses "did" as the past tense auxiliary verb and "do" as the base form of the main verb, aligning with the past tense context of the sentence.
