Complete Question Explanation

Cannot Be True, Formal Logic. The correct answer choice is (C).

The stimulus contains a Fact Set.

The first sentence contains several parts, but we will reduce it to the following:

  • Veterinarian (Esp Uni Vet Research Centers) :most: Devoted interest in biological sciences

The second sentence gives us:

  • Veterinarian :most: choose their profession primarily because they love animals

This connects to the first sentence via "Veterinarian," but we'll leave it diagrammed separately for now to avoid any confusion over the "especially those at university veterinary research centers" portion. Just know that the "double most" arrangement here means there must be an overlap between "Devoted interest in biological sciences" and "choose their profession primarily because they love animals."

The third sentence combines groups from the prior two sentences and is easily the most confusing sentence here, which means it's also the most likely ground for producing our correct answer.

Per the explanation below, the key is in the last sentence. If we were to put this statement in our own words, it would tell us “Within people who are interested in bio sciences but have no special love for animals, there are no prominent veterinarians” or “If you are a person who is seriously interested in biological sciences but don’t have any special love for animals, you are not a prominent veterinarian”

We are basically given the condition that prominent veterinarians do not have the qualities of serious interest in biological science coupled with a lack of special love for animals.

  • Serious interest AND special love :arrow: prominent veterinarian

With some of the relationships established, let's look at each answer. Remember, in a Cannot question the four incorrect answers Could Be True and the one correct answer Cannot be the case.

Answer choice (A): The relative strengths ("greater") of love haven't been addressed, and thus could be true and is incorrect.

Answer choice (B): This could be true and is thus incorrect. We know at least "some" have this overlap, and there's nothing stopping "most" from having both traits.

Answer choice (C): This is the correct answer choice because it tells us some prominent veterinarians can have devotion to the biological sciences while also having a lack of love towards animals. This directly contradicts the final sentence, and so answer choice (C) is the correct answer for the CANNOT be true.

Answer choice (D): This could be true and is thus incorrect.

Answer choice (E) is a tricky one but ultimately it is not addressed directly in the stimulus and so it is possible. We are not told in the stimulus what qualities are relevant for success, so we cannot definitively say what can and cannot be true about this.

I got the answer correct, but it was super lucky- I had it down to C and E, and E just seemed wrong because those interested in biological sciences (more than love for animals) may not be a prominent veterinarian (which could be true). However, I don’t know why specifically C is correct. I tried using formal logic and just confused myself further…

Hi D,

The key is in the last sentence. If we were to put this statement in our own words, it would tell us “Within people who are interested in bio sciences but have no special love for animals, there are no prominent veterinarians” or “If you are a person who is seriously interested in biological sciences but don’t have any special love for animals, you are not a prominent veterinarian”

We are basically given the condition that prominent veterinarians do not have the qualities of serious interest in biological science coupled with a lack of special love for animals.

  • Serious interest AND special love ----> prominent veterinarian

Answer choice (C) is the correct answer because it tells us *some* prominent veterinarians can have devotion to the biological sciences while also having a lack of love towards animals. This directly contradicts the final sentence, and so answer choice (C) is the correct answer for the CANNOT be true.

Answer choice (E) is a tricky one but ultimately it is not addressed directly in the stimulus and so it is possible. We are not told in the stimulus what qualities are relevant for success, so we cannot definitively say what can and cannot be true about this.

Hope this helps!

I think its fair to note however that according to Powerscore chapter on CANNOTBETRUE.
"The stimuli in Cannot Be True questions rarely contain a conclusion"

I answered incorrectly because this idea didn't come to mind when this question came up.

Hi C,

I have adjusted the explanation in the prior post as it was inaccurately saying the last sentence is a conclusion. It is not, and it is just another factual statement like the first two sentences. Thus, this is a typical Fact Set like you see in most Cannot questions :-D

That said, while the statement in the Cannot chapter is the case, it also explicitly allows for exceptions ("rarely"). Had this been a conclusion, I'm not sure how I see that would have caused you to miss this problem. Meaning, had it been a conclusion, you are still told in the question stem to accept all the statements above as true, so it would be true regardless. Can you tell me what effect you thought it being a conclusion had on you?

Thanks!
