Final answer:
The phrase "The corner to the left" is a sentence fragment because it lacks a complete subject and verb, rendering it an incomplete thought. The correct answer is option: B. The corner to the left.
Step-by-step explanation:
Reviewing Common Sentence Errors: Understanding sentence fragments is important as they are a common sentence error. Fragments can make writing unclear, as they are incomplete thoughts. To correct a fragment, one must ensure that the sentence has at least a subject and a main verb so it can stand alone as a complete thought. If the fragment is a subordinate clause, it must be connected to a main clause to form a complete sentence.
The group of words that is a sentence fragment is "The corner to the left." This group of words lacks a subject and a verb, which are necessary components of a complete sentence. Sentence fragments cannot stand alone as a complete thought and therefore do not form a complete sentence. They can be corrected by adding the missing elements or by attaching them to a neighboring sentence that they are intended to complete.
