Question

is the group of words in bold a phrase or a clause? many traditional pets have lived in the white house, but some former presidents kept unique companions; for example, john quincy adams had an alligator that lived in a white house bathroom. phrase clause

Explanation:

A clause has a subject and a predicate (a verb - expressing action or state). The bolded group "some former presidents kept unique companions" has a subject ("some former presidents") and a predicate ("kept unique companions" with the verb "kept"). A phrase lacks a subject - predicate structure. So it's a clause.

Answer:

clause
