2. Who gets the reward?

3. Who will be staying with you this summer?

4. Whom will you contact at headquarters?

5. Who is available to babysit for me on Saturday?

6. Who would like to travel to Vancouver Island next summer?

7. Who raced in the track meet?

*10. .....is your best friend?

The last two, I'm not sure. Could you help please.

After this, I will be confident that I understand.

Thanks very much!

Your first 8 are right! :-)

The last two are tricky. In both sentences "who" is the subject of the verbs -- is and are.

No problem! Let's go through each sentence and determine whether "who" or "whom" is correct.

1. Whom would you choose as the winner?
Explanation: To determine whether to use "who" or "whom," you need to identify the subject and the verb in the subordinate clause. In this case, the subject is "you" and the verb is "would choose." Since "whom" is the object form of "who," it is correct to use it here. Correct sentence: "Whom would you choose as the winner?"

2. Who gets the reward?
Explanation: In this sentence, "who" is the subject of the verb "gets," so it is correct. No change needed. Correct sentence: "Who gets the reward?"

3. Who will be staying with you this summer?
Explanation: Here, "who" is the subject of the verb "will be staying," so it is correct. No change needed. Correct sentence: "Who will be staying with you this summer?"

4. Whom will you contact at headquarters?
Explanation: Similar to sentence 1, "whom" is the object of the verb "contact." Correct sentence: "Whom will you contact at headquarters?"

5. Who is available to babysit for me on Saturday?
Explanation: "Who" is the subject of the verb "is available." No change needed. Correct sentence: "Who is available to babysit for me on Saturday?"

6. Who would like to travel to Vancouver Island next summer?
Explanation: "Who" is the subject of the verb "would like." No change needed. Correct sentence: "Who would like to travel to Vancouver Island next summer?"

7. Who raced in the track meet?
Explanation: "Who" is the subject of the verb "raced." No change needed. Correct sentence: "Who raced in the track meet?"

8. Whom did they meet at the airport?
Explanation: Here, "whom" is the object of the verb "meet." Correct sentence: "Whom did they meet at the airport?"

9. Whom are your three favourite authors?
Explanation: In this sentence, "whom" is the object of the verb "are," but it does not sound natural. It is more common to use "who" here. Correct sentence: "Who are your three favourite authors?"

10. .....is your best friend?
Explanation: This question is incomplete, so it's difficult to determine whether "who" or "whom" would be correct. Please provide the missing subject to receive a full answer.

I hope this helps! If you have any more questions or need further clarification, feel free to ask.
