Tenses MCQ Questions and Answers | English Grammar MCQ

The correct answer is Option C: did / do.
Let's break it down:
The sentence asks about an action completed in the past ("last week").
Therefore, we need to use the past simple tense.

The auxiliary verb used for questions in the past simple tense is "did".
So, the first blank should be filled with "did".

After "did" in a question, the main verb goes back to its base form (present form).
The base form of the verb "did" (to do) is "do".

Therefore, the correct sentence is: "What work did you do last week?"

Let's look at why the other options are incorrect:
Option A: were / do - "Were" is used with continuous tenses or past tense with plural subjects, not for forming questions about simple past actions with singular subjects like "you".
Option B: did / did - Using "did" twice in this structure is grammatically incorrect. You only need one "did" to indicate the past tense.
Option D: do / did - This option puts the verb in the present tense ("do") before the time indicator "last week", which doesn't make sense.

The present simple tense is used for habits, general truths, and repeated actions.

lose and explode are in the present simple tense, indicating that losing temper and exploding happen from time to time.

lost/am exploding is incorrect because it mixes past tense with present continuous tense.

have been losing/exploding is incorrect because it uses the present perfect continuous tense, which implies an ongoing action that started in the past and is still continuing.

were losing/have exploding is incorrect because it uses the past continuous tense with an incorrect form of present perfect continuous tense.

have lost/was exploding is incorrect because it uses the present perfect tense with the past continuous tense.

Therefore, the correct answer is lose/explode.
