Final answer:
The correct answer is A) Corinne took summer courses, and she devoted her spare time to tennis. This maintains active voice and verb tense consistency, unlike the other options.
Step-by-step explanation:
To correct the shift in verb voice or mood in the sentence "Corinne took summer courses, and her spare time was devoted to tennis.", we should choose the option that maintains consistency in the voice. The correct answer is: A) Corinne took summer courses, and she devoted her spare time to tennis.
This revision eliminates the passive voice found in the original sentence by making both clauses active and maintains verb tense consistency. Both actions are in the past, which aligns with the initial clause. Option B uses passive voice unnecessarily; option C shifts the tense to the present incorrectly, and option D changes the tense of the first verb incorrectly.
