5. (C)
Question type: Infer
This question asks us to find an answer that we can prove to be FALSE according to the given statements. Looking at the statements, one should notice that the majority of them include the word "some", which only tells us that at least one member of a group has a certain characteristic. Since this argument contains so many different categories, it’s best to start by looking at the statements that are more restrictive. The final sentence definitively states that there is not one prominent veterinarian who is both seriously interested in biological science and does not have a special love for animals. Answer (C) is therefore impossible, since it proposes that there is a prominent veterinarian with those characteristics.
(A) is possibly true. There is no limitation on at least one veterinarian loving science more than individual animals. The inclusion of "individual" is a red flag.
(B) could be true since the only group that is restricted in their love for animals is prominent veterinarians who are seriously interested in biological sciences.
(D) is out of scope, and is therefore possible, since there is no discussion of the motivation of veterinarians at university research centers
(E) is out of scope, and is therefore possible, since the statements do not discuss the opinion of any veterinarian, let alone a non-prominent one.
