Correct option is A
The correct substitution of the highlighted words is
(a) very well.
Explanation: The verb
did requires an
adverb to modify it.
Good is an adjective; the adverb form is
well. Therefore,
“She did her work
very well
.” is grammatically correct and idiomatic.
Grammatical rule used:
·
Adverbs modify
verbs (how an action is performed):
do
well ,
sing
beautifully .
·
Adjectives modify
nouns:
a
good
singer.
·
Example:
· Correct:
He performed
very well
in the exam.
· Incorrect:
He performed
very good
in the exam.
·
Information booster:
·
too well suggests excess (possibly negative):
She did the task
too well
(implying overkill).
·
quite good/really great are adjective phrases and don’t fit after
did unless rephrased (e.g.,
Her work was quite good).
