Answer:
Chemistry professor with a doctoral degree.
Step-by-step explanation:
This is the person who is most likely to earn the highest pay. There are two reasons for this. First of all, this person is a full-time professor, and not a teaching assistant, which makes his pay higher. The second reason is that this professor has the highest level of education, as he has a doctoral degree. This also warrants a higher pay compared to the other people.
