Explanation:

- The passage describes a military exercise performed at the border between Amritsar and Lahore, which involves ceremonious actions suggesting aggression but ultimately ends in a peaceful gesture with the lowering of flags.

- The word for blank no. 3 needs to describe the nature of the glares exchanged between soldiers during the drill.

- Option 1: Silly - This would not match the context of a military drill, which is serious and full of meaning.

- Option 2: Witty - This suggests cleverness or humor, inappropriate for a tense border ceremony.

- Option 3: Fierce - This accurately reflects the intensity and aggressive nature of the glares during the drill.

- Option 4: Diverting - This means entertaining or amusing, which is not suitable for describing the aggressive demeanor in a military context.
