Question

is the group of words in bold a phrase or a clause? did you know that tarantulas can survive for as long as two years without food? phrase clause

Explanation:

A clause contains a subject and a predicate (a verb and what it relates to). The bolded group "can survive for as long as two years" has the subject (implied or related to tarantulas) and the verb "can survive" with its complement. A phrase lacks a subject - predicate structure. So it's a clause.

Answer:

B. clause
