Question

select the group of words below that is an example of alliteration.
snow slid silently down the window of the old barn and dripped on the frozen earth below.

Explanation:

Alliteration is the repetition of initial consonant sounds in adjacent or closely connected words. The phrase "the frozen earth below" has repeated initial /f/ and /e/ consonant sounds (frozen, earth; below also has a soft /b/ but the key repeated initial sound is /f/ for "frozen" and the adjacent structure, while "earth below" shares the initial /e/ sound). The other phrase does not have this repeated initial consonant pattern.

Answer:

the frozen earth below
