From the words or group of words lettered A to D, choose the one that best completes the sentence.
She can't sing ..as I had thought
Answer Details
The correct option is "as well". The sentence implies that the speaker had a certain expectation of the person's singing ability, but that expectation was not met. "As well" is used to compare the actual singing ability to the speaker's expectation, indicating that the person's singing ability is not as good as the speaker had originally thought.
