Question

which of the following reflects the best definition of antidepressant?
a something that stands against depression
b something that happens before depression
c something that happens in the middle of depression
d something that is beyond depression

Explanation:

The prefix "anti -" means against. So, an antidepressant is something that acts against depression. Option A correctly reflects this meaning. Option B ("before") is incorrect as "anti -" does not mean before. Option C ("in the middle") is wrong as the prefix does not imply that. Option D ("beyond") is also incorrect since "anti -" is about opposition, not going beyond.

Answer:

A. something that stands against depression
