Most veterinarians, and especially those at university veterinary research centers, have a devoted interest in the biological sciences. But most veterinarians choose their profession primarily because they love animals. Among persons who are seriously interested in biological science but lack any special love for animals, one does not find any prominent veterinarians. If all of the statements above are true, which one of the following CANNOT be true? ['Few veterinarians at university research centers chose their profession primarily because they love animals.', 'Prominent veterinarians at some veterinary research centers are intensely devoted to the biological sciences but do not feel any pronounced affection for animals.', 'Most veterinarians who are not prominent regard an understanding of the biological sciences as the most important quality for success in their profession.', 'Some veterinarians have a greater love for biological science than for individual animals.']
