WRITE the adverb form that correctly completes the sentence. Hawks resemble falcons (close) of all birds.
I'll be glad to check your answer.
Hint: Think of a common adverb suffix.
Is it more closely?
Yes, you have the adverb form of close. But the sentence still doesn't make much sense.
It should be
Hawks resemble falcons more closely than other birds.
The adverb form that correctly completes the sentence is "closely."
To find the adverb form, we need to identify the adjective form and add the -ly suffix. In this case, the adjective form of "close" is "close," so we add -ly to form "closely."
