问题 How can the credit card recognize the spoken password given by the user?
According to the last paragraph, what is NOT involved in the process of using the voice card?
选项 A、Switching on the electronics to maximize the battery life.
B、Pressing the "Say your password" button on the card’s surface.
C、The password is verified.
D、The ID squawk is sent to the server for it to identify.
答案A
解析 A具有干扰性：To maximize battery life，the electronics are only switched on when the card is being used．原文说“为了延长电池的寿命，只有当信用卡被使用的时候，电路才接通”，而不是A中说的“接通电路以延长电池的寿命”。其余的选项在文章中都有呼应的内容：pressing a button on the card’s．If the voice-recognition software proves that the password is authentic(与C一致)it sends its ID squawk which the server then identifies(与D一致)，allowing the transaction to proceed．
