Question

read the sentence. id like to study biology or math, but it will be difficult. which sentence corrects the vague pronoun problem in this sentence? ○ id like to study either one, but it will be difficult. ○ id like to study biology or math, but they will be difficult. ○ id like to study them, but making a choice between the two will be difficult. ○ id like to study biology or math, but choosing between the two will be difficult.

Explanation:

The original sentence has a vague pronoun "it" that does not clearly refer to what is difficult. We need to identify the option that removes this vagueness by clearly stating what the difficult task is.

1. The first option still uses the vague "it", so it does not fix the problem.
2. The second option changes "it" to "they", which incorrectly implies both subjects are difficult, not resolving the original vagueness.
3. The third option uses "them" without first establishing clear referents, creating new vagueness.
4. The fourth option explicitly states that "choosing between the two" is the difficult task, completely eliminating the vague pronoun issue.

Answer:

I'd like to study biology or math, but choosing between the two will be difficult.
