Select the word or phrase in the sentence that is not used correctly: 'The teacher let the students know that they would have 1 hour to complete the test.'

  • A. the test
  • B. let
  • C. would have
  • D. to know
Correct Answer: D

Rationale: The correct answer is D. 'To know' is incorrectly used here; it should be 'know' without the preposition 'to.' The verb 'let' is followed by the base form of the verb, not the infinitive form. Therefore, the sentence should read, 'The teacher let the students know that they would have 1 hour to complete the test.'
