1. Wish I had met him a week ago. (D)
Explanation: The verb "wish" is used to express a desire for something that is not true or possible in the present. In this case, the speaker is expressing a regret that they did not meet him a week ago. Since the action of meeting him did not happen in the past, we use the past perfect tense "had met" to show that it is a past regret.

2. If I were you, I would buy a computer. (A)
Explanation: This is a conditional sentence in the subjunctive mood. The correct answer is "were" (A) because it is used to express a hypothetical situation or a counterfactual condition in the present. The speaker is imagining what they would do if they were in the other person's position.

3. Were he older, he would understand it. (D)
Explanation: This is another conditional sentence in the subjunctive mood. The correct answer is "were" (D) because it is used to express a hypothetical situation or a counterfactual condition in the present. The sentence is saying that if he were older (which is not true), he would understand it.

4. They would have noticed it if she had been upset that evening. (C)
Explanation: This is a conditional sentence in the past perfect tense. The correct answer is "had been" (C) because it refers to a past condition that did not happen. The sentence is saying that if she had been upset (which is not true), they would have noticed it.

5. Nobody will be able to help you unless you tell us the whole story. (D)
Explanation: The correct answer is "tell" (D) because it is the simple present tense. The sentence is expressing a general truth or a fact that will happen in the future. It is saying that unless you tell us the whole story, nobody will be able to help you.

6. If I had more free time today, I would read the book you gave me. (C)
Explanation: This is a conditional sentence in the past simple tense. The correct answer is "would read" (C) because it refers to a hypothetical situation or a counterfactual condition in the past. The speaker is imagining what they would do if they had more free time today.

7. Had I not missed the bus, I wouldn't have been late for work. (B)
Explanation: This is a conditional sentence in the past perfect tense. The correct answer is "wouldn't have been" (B) because it refers to a past condition that did not happen. The sentence is saying that if the speaker had not missed the bus (which is not true), they would not have been late for work.

8. If I were you, I would have stayed at home yesterday. (B)
Explanation: This is a conditional sentence in the past perfect tense. The correct answer is "had stayed" (B) because it refers to a hypothetical situation or a counterfactual condition in the past. The speaker is imagining what they would have done if they were in the other person's position.
