In a blow to those who still harbored the illusion that E-mail exchanges are private, a watchdog group recently uncovered a trick for enabling an interloper to rig an E-mail message so that this person will be privy to any comments that a recipient had added as the message is forwarded to others or sent back and forth. 既然是recently 怎么能用过去时呢？全都是过去时，只能在全句中找时态一致的了

recently 可以和过去时一起用啊。

a watchdog group recently uncovered a trick 是过去时。be privy的时态和add的时态都在uncovered之后。对比一下个选项这两个动词的时态，应该是一致的才对。

A will be privy和had added

B was privy和might have added

C is privy说明是一般的特性，不是什么条件使他变得privy

E was privy看不出是uncovered之后的变化成的privy。
