Final answer:
The sentence fragment is option A, "Kenji going to the movies later this evening," because it lacks a complete verb phrase. Unlike a complete sentence, a sentence fragment cannot stand alone as a complete thought. Sentence fragments can be unintentionally or intentionally used, particularly in creative contexts.
Step-by-step explanation:
The sentence fragment in question is option A, "Kenji going to the movies later this evening." This is a fragment because it lacks a proper verb to make it a complete sentence. It seems to be missing an auxiliary verb such as 'is' to complete the verb phrase (is going).
In contrast, the sentence provided in option B, "My shirt shrank in the hot water I should have read the label first," is actually two complete sentences run together and while it is incorrect, it is not a fragment; it is a run-on sentence.
Sentence fragments often follow a complete sentence to provide additional information but lack the proper structure to stand alone.
An example of unintentional fragment usage would be taking a sentence such as 'I lost a glove on my walk,' and adding 'but found it later' without properly connecting the two with a conjunction or punctuation, creating 'I lost a glove on my walk but found it later.' In some cases, intentional fragments are used for effect in writing, particularly in creative writing and advertising.
