Select the word or phrase that makes the following sentence grammatically correct. Two students ___________ the machine while the third oversaw their work.

  • A. operate
  • B. operating
  • C. were operating
  • D. has been operating
Correct Answer: A

Rationale: The word 'operate' is the correct choice as it agrees with the verb tense used in the sentence. In this case, the sentence requires the simple past tense. The correct form should be 'Two students operate the machine while the third oversaw their work.' Choices B, C, and D are incorrect because they do not match the required verb tense for the sentence. 'Operating' (choice B) is a present participle, 'were operating' (choice C) is past continuous, and 'has been operating' (choice D) is present perfect continuous, none of which fit the context of the sentence.
