2.2. What does the underlined word “malfunction” probably mean?

A Work well.

B Break down.

C Stay quiet.

解析：选B。B 词义猜测题。根据第三段 Claire In的话 “Robots can malfunction at any time, and even a small mistake could be dangerous” 及后文语境可知，“malfunction” 后提到 “小错误会很危险”，说明这是机器人出现问题的情况。结合第一段 Oscar 提到的 “if the robot breaks down”（如果机器人出故障），可推测 “malfunction” 与 “break down” 意思相近，指 “出故障、失灵”。故选B。
