What part of speech is represented by the word in parentheses: I listened in the lesson but I didn't remember it very (well).

The word in parentheses, "well," functions as an adverb in the given sentence. It describes how the action of remembering was performed. Adverbs modify verbs, adjectives, or other adverbs, providing more detail about the manner, degree, or frequency of the action. In this context, "well" specifically indicates the quality of the memory related to the lesson.

Understanding the role of "well" is important because it emphasizes the degree to which the speaker was able to remember the lesson. An adverb helps convey information about how effectively the listener retained the information. This distinguishes it from other parts of speech in the options provided, as they do not accurately describe the function that "well" serves in this particular sentence.
