Ms Henson, a supervisor with five years of experience

complete or incomplete senesce?

The correct answer to the question: Is this a complete sentence: Ms. Henson, a supervisor with five years of experience, is, that this is a totally incomplete sentence.

Explanation:

The reason for this being the answer is that aside from the main claim, which is that Ms. Henson has been a supervisor for five years, we don't know anything else. What is it making reference to? Why are they mentioning such information, what would be its purpose? None of this can be ascertained because there is no further information, and the sentence lacks a second clause to make this clearer. This is why it is an incomplete sentence.

This is an incomplete sentence, since it is not expressing a complete thought.
