"Opt-out" mechanism is probably ______.
A．a machine that can be attached to your computer
B．a button that you can make a choice to read or not to read
C．a software that you can play a computer game
D．an e-mail that says some good words to you
参考答案
正确答案：B
解析：细节题型。第四段第二句是个对比句：While some senders…provide simple and reliable ways for recipients to reject (or‘opt-out’of)receipt of．．．，other senders，provide no such‘opt-out’mechanism．．．从中得知‘opt-out’应是reject的近义词；而‘opt-out’ mechanism应是前半句中提到的simple and reliable ways for recipients to reject receipt of．．．；因此选项B最符合题意。
