(单选题)

According to Kocher, ______.

A.it’s difficult for microprocessors to balance speed and security

B.compared with Meltdown, Spectre is an urgent crisis

C.Meltdown will trouble us in a long time

D.as long as microprocessors run fast, no issue will occur

参考答案：A

参考解析：

推理判断题。根据最后一段可知，Kocher认为，在设计新芯片时一味强调速度使它们容易受到安全问题的影响，Spectre表明你不能两者兼得，也就是说很难平衡速度和安全的问题，A项正确；B项刚好相反，Meltdown才是an urgent crisis；C项也刚好相反，Spectre才会困扰我们很久；D项错误，光追求速度，势必会有安全问题。故选A。
