Either the students or the teacher ______ the camera.

• A. has broke
• B. have broke
• C. has broken
• D. have broken

Answer: (C)

The correct answer is "has broken" because the subject of the sentence is "either the students or the teacher," which is a compound subject governed by the nearest singular noun, "teacher." In English grammar, when using the structure "either...or," the verb must agree with the part of the subject that is closest to it. Since "teacher" is singular, the appropriate verb form is "has."

Furthermore, the verb "broken" is the past participle of "break," which fits correctly with the auxiliary verb "has" to form the present perfect tense. Thus, the complete sentence reads, "Either the students or the teacher has broken the camera," indicating an action that has occurred in the past and is relevant to the present.
