Pronoun ambiguous antecedent

[kr.manid]

Is the below rule correct:
RULE: If a noun is neither subject or object of main clause/sentence then it doesn't introduce pronoun ambiguity in that sentence.

IN OG#13 Q6 : why them cannont refer to Tourists.

one explanation but not convinced: 'THEM' is not referring to tourist because it is neither the subject nor object of the sentence. This is one of the GMAT trap. In short, THEM correctly refers to subject of the sentence, i.e. CHAMBERS

I have noticed in many cases that subject pronoun refers to preposition nouns or noun phrases.

Correct me if I am wrong.

Thanking you in advance and any comments would be appreciated.

Thank you for asking the question. I was also thrown off by the same problem as well where I crossed out the correct answer choice because of the pronoun "them". Can you please explain that problem and the underlying rule here?

Can any instructor shed some light on this post?

Thanking you in advance.

No, that "rule" sounds a little dangerous to me. While it's often true that subjects make stronger antecedent candidates than other nouns, the location and usage of the pronoun have a lot to do with this.

We can't discuss any OG problems on this forum for copyright reasons, but similar questions have been asked about other problems. Check out the following:
