Here's why:
* Degrees of comparison are used to compare things (adjectives and adverbs). They are usually expressed as:
* Positive: The base form (e.g., quiet)
* Comparative: Comparing two things (e.g., quieter)
* Superlative: Comparing three or more things (e.g., quietest)
* In the sentence, "quiet" is used as an adjective describing the state of the audience. It's not comparing the audience's quietness to anything else.
