Final answer:
The correct word to use in the sentence 'He reacted _____ to the news' is 'angrily'. This is because we need to use an adverb to describe how the verb 'reacted' was done.
Step-by-step explanation:
In the sentence "He reacted _______ (angry/angrily) to the news.", the correct word to use is 'angrily'. This is because 'reacted' is a verb, and we need an adverb to describe how the action was performed.
An adjective modifies a noun (i.e., angry man), whereas an adverb modifies how an action is performed (i.e., reacted angrily).
So the correct sentence is: "He reacted angrily to the news."
