clarification

I just want to make sure I'm doing this correctly.. So (A) could be true based on combining the 2 quantifier statements? I combined V-most-DIBS and V-most-CPLA to conclude DIBS-some-CPLA. (B) could be true given the quantifier statement V-most-DIBS? In this answer choice, it says "an interest in biological science," whereas the passage states "devoted interest in biological science." Could we eliminate this answer choice in assuming that "an interest" is different than a "devoted interest"? Could (D) be true given CPLA-some-V?

how do I diagram, "Among persons who are seriously interested in biological science, but lack any special love for animals, one does not find any prominent veterinarians?"

So far, I have

V-most-DIBS
DIBS-some-V

V-most-LA
LA-some-V

V=veterinarians
DIBS=devoted interest biological science
LA= love for animals

@jsmart3211,

Here's how I would diagram that sentence:

Seriously Interested and Lack Love - >Not Vet (or /Vet)

In questions asking for what cannot be true (must be false), the test often gives you a conditional statement, and the correct answer is usually a negation of this conditional statement.

A - ->B

The negation of this is A and /B; A and /B is a contradictory statement to A - >B

Based on the mapping we have above, we're looking for an answer choice that would provide a negation to that conditional statement

Seriously Interested and Lack Love - ->Not Vet

Negation: Seriously Interested and Lack Love - ->Vet

Answer choice C provides us with this negation, as it states that there are vets that are intensely devoted to the biological sciences but do not feel pronounced affection for animals. This cannot be true based on what's provided in the stimulus.

Hope this helps. Let us know what you think!

Can you not take the contrapositive of the last premise?

@Samantha-Alexis,

Yes, you can take the contrapositive of the last premise. The contrapositive is

Vet - >Don't Lack Love OR Not Seriously Interested in BS

Taking the contrapositive also allows us to see how (C) cannot be
true. The stimulus told us that there aren't prominent vets who're
interested in science but do not love animals, so (C) is impossible.

Does this make sense? Let us know if you have any more questions!
