词汇与结构 In this case the headset is switched automatically to a cabin loudspeaker, with the pilot using the microphone in the mask which may ______ the readability to ATC. A. increase B. add C. reduce D. keep

正确答案是 C. reduce。

句子意思是：在这种情况下，耳机自动切换到客舱扬声器，飞行员使用面罩中的麦克风，这可能会降低对空管（ATC）的语音可读性。

解析：

increase（增加）和 add（添加）在这里不合逻辑，因为面罩中的麦克风通常不如耳机麦克风稳定，容易受环境噪音影响，所以更可能降低清晰度。
