14. Which of the following is a compound sentence?

Answer: C

Explanation:

He ran, but she ran faster.

A compound sentence is defined as a sentence that contains at least two independent clauses joined by a coordinating conjunction. The sentence "He ran, but she ran faster" contains two independent clauses: "He ran" and "she ran faster," connected by the conjunction "but."

A) He will not run today.

This option is a simple sentence as it contains only one independent clause. It does not include any conjunction or another independent clause, therefore it does not qualify as a compound sentence.

B) Swimming is extremely fun.

This option is also a simple sentence with only one independent clause. It expresses a single thought without the presence of another clause or conjunction, and thus cannot be classified as a compound sentence.

C) He ran, but she ran faster.

This option is a compound sentence because it consists of two independent clauses: "He ran" and "she ran faster," joined by the coordinating conjunction "but." This structure is what defines a compound sentence.

D) I don't like to run or swim.

This option is a simple sentence that contains only one independent clause. Although it includes the conjunction "or," it does not connect two independent clauses, so it does not meet the criteria for a compound sentence.

Conclusion

The correct answer is "He ran, but she ran faster" as it meets the definition of a compound sentence with two independent clauses connected by a coordinating conjunction. The other options are either simple sentences or fail to combine multiple independent thoughts, making them incorrect in this context.
