Show answer & explanation
Correct answer: A
Explanation
Correct Answer
as well as
Explanation
The sentence requires an equal comparison of an action (singing). When making an equal comparison using the "as...as" structure, you must use the base/positive degree of the modifier, not the comparative degree (better).
Furthermore, because the modifier describes how she performs the action (sings, a verb), you must use the adverb "well" instead of the adjective "good".
"Good" modifies nouns (e.g., She is a good singer).
"Well" modifies verbs (e.g., She sings well).
Therefore, "as better as" must be replaced with "as well as".
Key Points
Correct Phrase: She sings as well as a trained vocalist.
Why "as good as" fails: While "as good as" is common in casual speech, grammatically it modifies nouns, not verbs. Since it modifies the verb sings, the adverbial form well is required.
Rule: as + positive adverb + as for comparing actions.
