Final answer:
Mark is a salesperson in pharmaceutical sales, interfacing with physicians to inform them about cancer-fighting drugs developed by his company, LiveLife Inc. His role is distinct from that of a pharmaceutical chemist, who works on drug development and experimentation.
Step-by-step explanation:
Mark is a salesperson who works for LiveLife Inc., a pharmaceutical company specializing in developing drugs for fighting cancer.
On a typical day at work, he meets several physicians and gives them information about the drugs being developed and manufactured by the company.
In this context, Mark is playing a vital role in the field of pharmaceutical sales. His job involves not only sales but also educational outreach as he informs healthcare professionals about new drug developments.
A pharmaceutical chemist on the other hand, might be involved in the initial stages of these drug developments, working through a mix of detective work, experimentation, and drug formulation, with the overarching goal of making human beings healthier.
