Question

1.) Identify the choice that best describes the problem

Answer 1

1.) A because the phrase is incomplete. 2.) let's see: not noun or independent automatically. No noun found and the phrase doesn't stand alone.
adverb asks how when where or why
Adjective asks what kind how many which one
I would go with Adverb.

Answer 2

1. The answer is A: Phrase fragment.  It doesn't have the complete idea, it is not an independent clause.

2. The answer is C: Adverb clause or Adverbial clause are dependent clause that has the function of an adverb, and connects to the rest of the sentence with a subordinating conjunction. (Description) In the sentence there is the subordinating conjunction Although (making contrast with the main idea).
