28. Which of the following is a complete sentence?

Answer: C

Explanation:

C is a complete sentence.

A complete sentence must have a subject and a predicate, conveying a complete thought. "I walked all three dogs around the park this morning" meets these criteria.

A) Running through the park before breakfast.

This option is not a complete sentence because it lacks a subject and a verb. It presents a phrase rather than a full thought, making it incomplete.

B) When I was young and loved going for runs in the park.

This choice is also incomplete as it begins with a subordinating conjunction, "When," and does not express a complete thought. It sets up a condition but does not provide the main clause needed for a full sentence.

C) I walked all three dogs around the park this morning.

This option is a complete sentence because it has a clear subject ("I") and a predicate ("walked all three dogs around the park this morning"). It conveys a full idea with both subject and action.

D) Walking with a limp as a result of the thorn.

This choice is not a complete sentence as it lacks a subject performing an action. It describes a scenario but does not provide a complete thought, making it an incomplete phrase.

Conclusion

Option C is definitively correct as it fulfills the requirements of a complete sentence by containing both a subject and a predicate, allowing it to express a full thought. In contrast, the other options fail to provide a complete idea, rendering them incomplete sentences. Thus, they cannot be considered correct.
