Actually, "theory of mind" is not a particular theory. It simply refers to our understanding of others as having mental states distinct from our own. (There's much debate about which species other than humans have theory of mind.) However, the GMAT won't rely on our content knowledge. As Mike and others have pointed out, there is plenty to disqualify E, and since that's the only choice with "the," we know "the" isn't needed. Honestly, it would be a little too good to be true if there were a clearly needed word that only occurred in one answer. I suppose that happens occasionally, but not much. It's more common that we decide a particular word or phrasing is needed without a strong basis for that decision, and then we end up crossing out the right answer prematurely.

Awesome explanantion and insight - I didn't realize that letter E is the only option with "the".
Thanks!

Hello GMATNinja, egmat,

The type of behavior exhibited when an animal recognizes itself in a mirror comes within the domain of “theory of mind,” thus is best studied as part of the field of animal cognition.


(B) “theory of mind,” and so is best to be
(E) of the “theory of mind,” and so it is best to be

Can I say that 'It doesnt make sense to have two conjunctions to join two IC

Interesting question. I wouldn't call "and so" a concrete error, because "so" can also be used as an adverb, meaning "thus" or "therefore." That construction could work in the right context. Better to see that the "to be" is, at best, unnecessary in both options and potentially confusing.

I hope that clears things up!

(A) of “theory of mind,” thus is best - The word thus is interesting, it explains a consequence ( means therefore) so logically it X happens and therefore Y happens , to explain this consequence 'and' is required, without an and it looks like 2 disjoint statements.
(B) “theory of mind,” and so is best to be - Parallelism is in mess here domain of X and so - of is missing; domain of something
(C) of a “theory of mind,” thus it is best - same as A + it does have a clear referrent ( domain , behaviour or animal)
(D) of “theory of mind” and thus is best - Explains the consequence properly and explains the scenario - Look at explanation of A, and is required
(E) of the “theory of mind,” and so it is best to be - it does have a clear referrent ( domain , behaviour or animal)

I also want to add that for option E, the use of 'and' is unnecessary because 'so', which is a conjunction, has been used already.

Two verbs with the same subject need to be linked with a coordinating conjunction (and, but, or, yet, etc.).
The book explains X, covers Y. (run-on sentence)
The book explains X, and covers Y.
The book explains X, but covers Y.

Thanks for this. Very helpful!

Hi GMATNinja

I think option 'c' - ( of a “theory of mind,” thus it is best) is wrong because of pronoun ambiguity and 'a' before “theory of mind,”.

", thus it is best" is the legit use as subordinate conjunction (Thus) can be used to join independent clause if it has right subject/pronoun and verb.

Your thoughts?

Thanks,
Akhil Shah

Remember that GMAT SC is about the BEST available option, not labelling individual choices as right or wrong in a vacuum.

For starters, is the "a" in (C) wrong? Maybe not, but at best it's confusing and unnecessary. The use of "a" makes it sound like there multiple "theory of mind" domains, and we're only talking about one of them -- and that's odd.

Is the pronoun in (C) wrong? Probably not, but at best it's confusing and unnecessary. (For more on how pronoun ambiguity isn't an absolute rule on the GMAT, check out this video or this newer one.)

Is the comma + "thus" in (C) wrong? Maybe not, but the parallel structure in (D) is clearer and easier to follow. Why split the sentence into two "halves" when both parts should be tied back to the same subject?

If you can convince us why the second half of (C) should be treated as a subordinate clause and not an independent clause, that's great. Regardless, there's no good reason to split the sentence into two "halves," so the comma + "thus" in (C) is at best [drumroll please] confusing and unnecessary.

I hope that helps!
