Explanation:

For Question 1: A sentence fragment lacks a complete thought, subject-verb pair that forms an independent clause. Option B is a dependent clause with no independent clause to complete the thought. Options A, C, D are complete independent clauses.
For Question 2: A correct sentence fixes run-ons properly. A run-on joins two independent clauses incorrectly. Option C (assuming it uses a semicolon or proper conjunction; based on standard correction, it properly separates the two independent clauses "The test was difficult" and "many students asked questions" with appropriate punctuation, while A is a fused run-on, B uses a comma splice, and D is incomplete in the image).

Answer:

Question 1: B. After the debate ended.
Question 2: C. The test was difficult; many students asked questions. (assumed correct formatting for the option as the image's C is partially cut off, following standard run-on correction rules)
