31. Which of the following is a complete sentence?

Answer: B

Explanation:

B: I walked all three dogs around the park this morning.

This option is a complete sentence as it contains a subject ("I") and a predicate ("walked all three dogs around the park this morning"), conveying a complete thought.

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

This option is not a complete sentence because it lacks a main clause. It presents a phrase that describes a condition but does not express a complete thought or action performed by a subject.

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

As noted, this option is complete. It has a clear subject and verb, and it provides a complete idea, making it the correct choice.

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

This option is also not a complete sentence. It begins with a dependent clause ("When I was young and loved going for runs in the park") but fails to provide an independent clause to complete the thought.

D) Running through the park before breakfast.

This option is a fragment and does not form a complete sentence. It describes an action but lacks a subject and a verb that would allow it to stand alone as a complete thought.

Conclusion

Option B is definitively the correct answer because it fulfills the criteria of a complete sentence, containing both a subject and a predicate that expresses a full idea. The other options, while they may convey thoughts or actions, do not meet the grammatical requirements to be classified as complete sentences.
