哪个词适合填入 “the sudden … of the quiet routine of his life”？

问题

He is still suffering from the sudden ... of the quiet routine of his life.

选项

1. disturbance
2. disconnection
3. mixing
4. trouble

解释

Disturbance 表示他平静的日常生活被打乱了。它在此语境中自然适合 “the quiet routine”。

Disconnection 意为分离或失去联系；mixing 意为混合事物。Trouble 意为困难或问题，但并不如这个结构那样贴切。
