With regard to academics, which person is not considered a doctor?
a) physician
b) physical therapist
c) personal trainer
d) lead medical researcher

C is the correct answer. "Academics" refers to training/education in a college or institute of higher education. No particular special training is absolutely required for a personal trainer, but an academic degree is required for the other professions, and advanced training is needed to even understand the issues and procedures of those professions.

The correct answer is C. A person trainer is not considered to be a doctor. Rather than the formal school training required by physicians, physical therapists, and medical researchers, the training and certification process for a personal trainer is much less intensive. In fact, one can become a certified personal trainer entirely online.

Its either c or d. i would go with d though, because im not sure if its legal in all of the us
