Complete the sentence: The research ethics board warned that under no circumstances ______ unauthorized patient data to be shared with commercial third parties.

Answer and explanation

Correct answer: D. will they permit

  1. Step 1: Identify negative restrictive phrase: 'under no circumstances' introduces a mandatory negative inversion.
  2. Step 2: Apply subject-auxiliary inversion: The modal auxiliary 'will' must precede the subject 'they'.
  3. Step 3: Select 'will they permit'.
Answer
will they permit.
Why not the others: 'they will permit' and 'they permit' lack the required inversion; 'did they permitted' combines auxiliary did with a past inflected verb.
