9. Identify the incomplete sentence.

Answer: C

Explanation:

While they were sleeping.

The phrase "While they were sleeping." is an incomplete sentence because it introduces a dependent clause that requires an independent clause to form a complete thought.

A) He wept.

This option is a complete sentence consisting of a subject ("He") and a verb ("wept"), expressing a complete thought. Therefore, it does not qualify as an incomplete sentence.

B) Everything worked out all right.

This choice is also a complete sentence, with a subject ("Everything") and a predicate ("worked out all right"), conveying a full idea. Thus, it is not an incomplete sentence.

C) While they were sleeping.

This option is an incomplete sentence because it begins with a subordinating conjunction ("While") and lacks an independent clause to complete the thought. It leaves the reader expecting additional information.

D) Babies are soft, cute, and cuddly.

This statement is a complete sentence with a subject ("Babies") and a predicate that describes them, making it a fully formed thought. Therefore, it does not meet the criteria for an incomplete sentence.

Conclusion

The choice "While they were sleeping." is definitively the correct answer as it presents an incomplete thought that requires further information to be understood. In contrast, all other options are complete sentences that express clear and standalone ideas, thus failing to meet the criteria of being incomplete.
