问题 The writer holds that_______.
According to the passage, an active noise-cancellation system______.
选项 A、contains noise rather than negates it
B、eliminates noise rather than muffles it
C、deflects noise rather than baffles it
D、holds noise hack rather than stifles it
答案B
解析 细节题。题意为："根据本文，一种主动消除噪音的系统______"。请参考文章第二段末句：现在利用计算机技术，发明了一种非常有效的"主动"的系统，它不是包容、转移或掩盖噪声，而是用电子的方式消除噪声。可知选项"消除噪声而不是减弱噪声"为正确答案。
