Classify the bolded word groups as either a phrase or a clause.

Here's the classification for each group of words:

1. Humans are classified as omnivores because they generally consume both plants and animals, although some people are vegetarians or vegans. The bolded part "they generally consume both plants and animals" contains a subject ("they") and a verb ("consume").

   • (ii) clause

2. Bonobos, chimpanzees, gorillas and orangutans—the four species of apes—differ from monkeys in their size, gait, brain development and absence of tails. The bolded part "the four species of apes" does not contain a verb. It functions as an appositive.

   • (i) phrase

3. The role of a prosecutor is to present a court case against an accused offender. The bolded part "to present a court case against an accused offender" is an infinitive phrase and does not contain a subject.

   • (i) phrase
