Question

1. a prefix meaning toward, or in the direction of.

a. ex- \tc. in-
b. ad- \td. post-

Explanation:

To solve this, we analyze each prefix:

• "ex - " means out of, from (e.g., exit).
• "ad - " means toward, in the direction of (e.g., advance, where "ad - " + "vance" (go) implies going toward).
• "in - " can mean in, into, or not (e.g., inside, inactive).
• "post - " means after (e.g., post - war).

So the prefix meaning toward is "ad - ".
