Question

The diagnosis was described accurately. (Select the correct adverb.) Question 63 options: a) accurately b) described c) diagnosis d) was described

Answer 1

Was.

An adverb is a word or phrase that justifies a meaning for the sentence, in simple terms.

So here it would be "was", as opposed to "wasn't", I don't see any other potential for adverbs here, as diagnosis is the subject. Hope this helps.
