3. During the storm, the glass in three of the windows was broken.

Answer: C

Explanation:

The glass in three of the windows was broken.

The phrase "was broken" correctly indicates that the action of breaking occurred in the past and refers specifically to the glass in the windows during the storm.

A) Broken

"Broken" is simply the past participle form of the verb and lacks the necessary auxiliary verb to convey the passive voice needed in this context. It does not indicate when the action occurred nor does it fit grammatically into the sentence structure.

B) Breaks

"Breaks" is the present tense form of the verb, which is inappropriate for describing an action that took place during the storm. This choice does not convey the past action required by the context.

C) Was broken

"Was broken" is the correct choice as it uses the past tense in the passive voice, effectively communicating that the action of breaking occurred to the glass in the windows during the storm.

D) Were broken

"Were broken" is also in the passive voice but is incorrect because it implies a plural subject. Since the subject is "the glass," which is singular in this context, this option does not correctly match the subject-verb agreement needed.

Conclusion

Option C, "was broken," is definitively correct as it accurately conveys the past passive action affecting the singular subject, "the glass." Options A and B fail to provide the appropriate tense and structure, while D misaligns with the subject's number, confirming that C is the only suitable choice.
