Question

is the group of words in bold a phrase or a clause? among bats, there are species that can reach speeds of more than fifty miles per hour.

To determine if "more than fifty miles per hour" is a phrase or a clause, we analyze: a clause has a subject and a verb, while a phrase does not. This group of words has no subject - verb combination, so it's a phrase.
