Directions: Fill in the blank by choosing the right form of the given four alternatives.

He spoke as though he _______ very angry.

The phrase 'as though' introduces a hypothetical or contrary-to-fact situation, which requires the subjunctive mood. For statements that are clearly contrary to reality (like someone being angry when they're not), we use 'were' instead of 'was'. This is the subjunctive form of 'to be' used in hypothetical situations after 'as though' or 'as if'.
