Hi !!
<em>A COMPLEX SENTENCE</em> <em> consists of</em>
<em />
One independent clause and one or more subordinate clauses.
☺☺☺
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!
D. Parallelism
Based on Your dictionary, it states: “Parallelism has slightly different meanings, depending on the context, but it’s about balancing the weight or structure of ideas and phrases. In rhetoric, parallelism means balancing two or more ideas or arguments that are equally important.”
