In the anthology, i read a classic poem underline starts that was written underline ends over 500 years ago. which word does the underlined adjective clause modify?
a)anthology
b)classic
c)poem
d)years

The underlined adjective clause "that was written" is modifying the noun poem. In this sentence, the adjective is describing or adding further information about the poem. Option C is correct.

An adjective clause is a form of dependent clause which purpose is to describe a noun in a sentence. It works as an adjective even though it is made up of a group of words instead of just one word. In the case of an adjective clause, all the words are intended to modify or describe the noun or pronoun.
