【难句分析】　The researchers also tried to find out whether people would take action sooner if they were told a certain event was happening in several days rather than years.

分析：本句是一个主从复合句。whether引导宾语从句，作find out的宾语；if引导条件状语从句；“a certain event was happening in several days rather than years”是省略了that的宾语从句，作told的宾语。

译文：研究人员也试图弄清楚如果人们被告知某事将在几天而不是几年后发生，他们是否会更快采取行动。
