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:

In the original sentence, "it" is vague. The correct sentence should clearly show what is difficult. The first option still has a vague "it". The second option has a wrong - number pronoun "they" as only one subject is to be studied. The third option has a wrong pronoun "them". The fourth option clearly states that choosing between biology and math is difficult.

Answer:

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