jamal's neighbor tells him that there are more bacterial cells than human cells in his body. which of these is the best reason that jamal should question his neighbors statement?

a. jamal is older than his neighbor
b. jamal does not like his neighbor very much.
c. his neighbor's mother does research in chemistry
d. his neighbor does not know very much about biology

My answer:
either A or C

The best reason for Jamal to question his neighbor's statement would be option D - his neighbor does not know very much about biology.

To arrive at this answer, let's analyze the other options:

A. Jamal being older than his neighbor is not a relevant reason to question the statement. Knowledge about biology is not dependent on age.

B. Jamal not liking his neighbor does not have any bearing on the credibility of his neighbor's statement. Personal feelings do not determine the validity of scientific information.

C. Even though his neighbor's mother does research in chemistry, it does not necessarily make his neighbor knowledgeable about biology. The expertise in one field does not automatically translate to expertise in another.

Option D is the most appropriate because it directly addresses the knowledge and understanding of biology, the subject matter in question. By highlighting that his neighbor does not know much about biology, it indicates that the statement may not be accurate or reliable.
