Answer 1

Adverbs act as modifiers of verbs, describing their time, place, reason, or manner.

Step-by-step explanation:

Adverbs act as modifiers of verbs, describing their time, place, reason, or manner. Adverbs can end with -ly, such as "pouring pouringly more than 40 years." In the first blank, the correct adverb is a) After because it indicates a temporal relationship. In the second blank, the correct adverb is a) Although because it introduces a contrast.
