Hi !!
The team has much work to do before the big game.
BEFORE is a preposition.
means "earlier than"
-
explanation
When before is a subordinating conjunction, it links two clauses together.
ex : The team has much work to do <em>before they play the game.</em>
<em>-</em>
<em>☺☺☺</em>
An adverb is an adjective + a verb. Meaning, it's a word that describes what someone/something is doing during the action.
A (whistle) & C (referee) are both nouns - person, place, or thing.
D (red) is just an adjective - describing something
B would make the most sense, it's telling you what the referee does with his whistle.
Hope this helped!
