In which sentences should the pronoun who be replaced with whom to reflect correct usage?

Select the two correct answers.

A. Bryan, who loves playing soccer, was disappointed when he was cut from the team.
B. Dorothy is a professional pastry chef who can bake a great Chantilly tart.
C. Who do you think should be the next president of the science club?
D. Who wants to help clean the pool so that it will be ready when summer begins?
F. The water from the faucet has turned brown, but I’m not sure who to call about it.

C. Who do you think should be the next president of the science club?

F. The water from the faucet has turned brown, but I’m not sure who to call about it.

The two sentences in which the pronoun "who" should be replaced with "whom" are:

C. Who do you think should be the next president of the science club?
F. The water from the faucet has turned brown, but I’m not sure whom to call about it.

To determine which sentences require replacing "who" with "whom," we need to understand the difference between the two pronouns.

"Who" is used as the subject of a verb or as the subject complement, while "whom" is used as the object of a verb or preposition. Essentially, "who" performs an action, and "whom" receives the action.

Now let's examine the sentences:

A. Bryan, who loves playing soccer, was disappointed when he was cut from the team.
In this sentence, "who" is the subject of the verb "loves playing." It should not be replaced with "whom."

B. Dorothy is a professional pastry chef who can bake a great Chantilly tart.
Similarly, "who" is the subject of the verb "can bake." It should not be replaced with "whom."

C. Who do you think should be the next president of the science club?
Here, "who" is the subject of the verb "do you think." It should not be replaced with "whom."

D. Who wants to help clean the pool so that it will be ready when summer begins?
Once again, "who" is the subject of the verb "wants to help." It should not be replaced with "whom."

F. The water from the faucet has turned brown, but I’m not sure who to call about it.
In this sentence, "who" is the object of the verb "to call." It should be replaced with "whom."

Therefore, the two correct answers are:
- F. The water from the faucet has turned brown, but I’m not sure whom to call about it.
