Which word is used incorrectly in the following sentence? The professor was once an intern in this hospital back in the 1980s.

  • A. professor
  • B. once
  • C. intern
  • D. hospital
Correct Answer: B

Rationale: In the given sentence, the word 'once' is used incorrectly. The original sentence implies that the professor was an intern in the hospital at a specific time in the past, not just once. The word 'formerly' would imply that the professor used to be an intern but is no longer. Therefore, 'once' is the incorrect word choice in this context. The other options ('professor,' 'intern,' 'hospital') are all used correctly in the sentence.
