Hint:

Pay attention to subject-verb agreement and use the correct tense to maintain consistency in the sentence.

Answer 1

The Correct Option is C

Step 1: Subject-verb agreement and past tense consistency.
The verb "rose" correctly agrees with the singular subject "average test score." "Was working" also maintains consistent past tense.
Step 2: Review the options.
- (A) The verb "were rising" is incorrect because the subject is singular and requires "was rising" instead.
- (B) The verb "were rising" is incorrect, and "had worked" is not appropriate in this context.
- (C) Correct; the verb "rose" agrees with the singular subject and maintains consistent past tense.
- (D) "As" is unnecessary here and introduces a subtle change in meaning.
- (E) "Had worked" is incorrect, as the sentence is referring to an ongoing process.
Conclusion:
Option (C) is the best answer because it maintains proper subject-verb agreement and tense consistency.
