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.

这题我就只靠着trick for enabling vs trick that enables和时态来排除的，这句话从句子成分上可以怎么判断么？我感觉好像都差不多。
这个不是时态的问题。
for enabling是一个介词短语，enabling是动名词，没有逻辑主语。也就是说，句中我们无法知道是不是这个trick在发出enable这个动作。意思上相当于这个trick是为了让interloper能做什么而出现的，并不是它让interloper能做什么的。
但在逻辑上，watchdog group揭露的东西，一定是发出enable这个动作的，否则揭露这个trick也没什么实际意义。
