Question

is the group of words in bold a phrase or a clause? frankfurters, which are also known as wieners or hot dogs, originated in frankfurt, germany, and are traditionally made from pork and beef.

A phrase is a group of words without a subject - verb relationship, while a clause has a subject and a verb. The bolded group "Frankfurters, which are also known as wieners or hot dogs" contains a subject ("Frankfurters") and a verb ("are known"), so it has a subject - verb combination, making it a clause.
