Question

test part 1: identifying dependent and independent clauses
is the highlighted portion of the sentence a complete or incomplete thought?
annoyed by the spelling mistakes in the article,
uncle iroh took a red pen and began to edit it.
complete thought incomplete thought

Explanation:

A complete thought (independent clause) has a subject and a predicate and can stand alone. The highlighted portion "Annoyed by the spelling mistakes in the article," is a participial phrase acting as an adverbial modifier. It lacks a subject - predicate structure to form a complete sentence and can't stand alone as a thought, so it's an incomplete thought.

Answer:

Incomplete Thought
