Question 27

Which sentence wrongly adds do-support to a neutral subject question?

  1. Who opened the loading gate?
  2. What did cause the power cut?Bonne réponse
  3. What damaged the outer casing?
  4. Who did the receptionist contact?

Explication

In the faulty sentence, what is already the subject and therefore must be followed directly by caused. The other examples either keep subject-question order or correctly use did because a separate, known subject follows the wh-word.
