Harold and Kumar are pre-med and pre-pharmacy students, respectively. They complain to their biology professor that they should not have to study about plants because plants have little relevance to their chosen professions.
It would be best for these students, and for society in the long run, if their biology professor responds by
A) acknowledging their concern, and promising not to hold them responsible for any material on plants.B) chiding them for their careerist attitudes, and advising them to whine less and study more.
C) offering extra credit for a research paper on plants that harm humans, as well as plants that heal humans.
D) lowering the stress level by providing them with the relevant test questions from the upcoming test so they can research the answers ahead of time.
Answer: C
