定语 that reveal people will surrender personal information like Social Security numbers just to get their hands on a pitiful 50-cents-off coupon.

语法分析

本句的主干是Privacy economist Alessandro Acauisti has run a series of tests，tests后面跟一个that引导的定语从句对其进行修饰。该定语从句的主干是that reveal…，reveal后面跟一个宾语从句。该宾语从句的主干为people will surrender personal information，介词短语like…numbers作后置定语修饰information，不定式to get…coupon在宾语从句中作目的状语。

此句的重点在于定语从句的先行词是that前面的tests，也就是定语从句的主语。reveal作为定语从句的谓语动词后面紧接着包含一个宾语从句，这是这句话的难点。
