Complete the sentence: There was a strict procedure which involved warming the teapot, putting one spoonful of tea for each person into the pot and then filling _________ with boiling water.

• A. It
• B. Them
• C. Him
• D. There

Answer: (A)

Think about what is being filled. After warming the teapot and putting tea into the pot, the action needs a singular, non-human object to receive the boiling water. The correct pronoun is “it” because it refers back to the teapot/pot. Using “them” would imply multiple objects or people, “him” would reference a male person, and “there” is a place, not an object to fill. So the natural completion is filling it with boiling water, keeping the sentence parallel and grammatically smooth.
