Answer:
A venus fly trap <u>quickly</u> snaps shut around insects.
Explanation:
An adverb is a word that modifies, describes or gives more detail to verbs, adjectives or other adverbs, by providing information about place, time, manner, frequency, degree or condition. There are many types of adverbs, some of them have the “-ly” ending like <em>happily, quickly, carefully </em>and<em> daily, </em>while others do not like<em> yesterday, soon, now.</em>
We can improve the sentence by adding the adverb <em>quickly</em> that modifies the verb “snaps” and gives us information about the manner in which a venus fly trap snaps shut around insects.
