a chemist a biologist a geologist a physician
I gave my students this multiple choice question: A pharmaceutical company published experimental data showing that a new medication improved cholesterol levels in the people who participated in the study. Which professional most likely did not contribute to developing this medication?

Only one answer is correct among these 4 choices:
- a chemist
- a biologist
- a geologist
- a physician

Could you tell me which one is correct?

a geologist
