Identify the correct subjunctive form:

'The ethics committee insisted that the clinical trial ______ immediately until safety reviews are complete.'

Answer and explanation

Correct answer: A. be suspended

  1. Step 1: Verbs of demanding, recommending, or insisting take the mandative subjunctive in nominal 'that' clauses, using the bare infinitive.
  2. Step 2: In passive voice, this requires 'be + past participle': 'that the clinical trial be suspended'.
Answer
be suspended.
Why not the others: 'is suspended' uses indicative present instead of the subjunctive; 'suspends' is active indicative; 'was suspended' uses indicative past.
