Answer:
The sentence has one adjective and no articles.
Explanation:
An adjective is a word that modifies or describes a noun or a pronoun. And articles are determiners or noun markers that tell us the identifiability of the nouns. We have only three articles in gramma- a, an, the.
In the given sentence <em>"there are approximately sixty different species"</em>, there is just one adjective. The<u> adjective is "different"</u>, describing the noun 'species'. And there are no articles in the sentence.
Thus, the correct answer is the sentence has one adjective and no articles.
