Type: Adverb 

Answer 2

Answer:

Subordinate clause: "though a few come from England and France"

Type: Adverb clause.

Explanation:

A subordinate clause is a group of related words that have at least a subject and a verb, and that can not stand as a full sentence because it does not express a complete thought. There are three types of subordinate clauses: Adjective, adverb and noun.

Adverb clauses are the ones that modify, describe or add detail to adjectives, verbs or other adverbs. They can be identified because they usually begin with subordinating conjunction like until, though, because, where and when.

In the sentence provided, the subordinate clause is "though a few come from England and France" because it does not express a complete thought on its own, and it is also an adverb clause because it modifies the verb "are" and begins with a subordinating conjunction: "thought."
