Choose the option that best explains the idiom:

"The engineer decided to burn the midnight oil to submit the canal expansion tender on time."

Answer and explanation

Correct answer: D. Work late into the night with diligence

  1. Step 1: Determine the idiomatic meaning of the figurative expression "burn the midnight oil": historically referring to the consumption of lamp oil while working late into the night.
  2. Step 2: Apply the idiom to the engineering context: it describes working diligently into the late hours of the night to complete a critical project or deadline on schedule.
Answer
Work late into the night with diligence.
Why not the others: Accidentally starting an electrical fire, wasting valuable fuel, or complaining about illumination represent literal interpretations of "burn", "oil", and "light", failing to recognize the established figurative idiom.
