Choose the correct adverb to fill in the blank:

The protagonist initially seemed confident. But his voice trembled __ as he described the trauma.

eventually

Answer: (1) eventually

 Explanation: Here, we're looking for an adverb that describes when his voice trembled.

• Eventually indicates a gradual change from confidence to trembling, making it the most fitting choice.
• Curiously suggests questioning or inquisitiveness, which doesn't fit the context of trembling.
• Beautifully describes something aesthetically pleasing, not how his voice trembled.
• Silently implies no sound at all, which wouldn't be trembling.
