_____ did you choose as a tennis partner?
a. Who
b. Whom
a. Who
To determine whether to use "who" or "whom" in the question, we can consider the function of the word in the sentence.
In this case, the word "_____ did you choose as a tennis partner?" is the subject of the sentence and is referring to the person you selected as a tennis partner.
To choose between "who" or "whom," you can follow these steps:
1. Determine if the word is functioning as the subject (nominative) or object (accusative) in the sentence.
2. If the word is the subject, use "who."
3. If the word is the object, use "whom."
Asking "Whom did you choose as a tennis partner?" would be grammatically correct because "whom" is functioning as the object of the verb "did choose."
The correct answer is:
b. Whom
