单纯的一道高一英语翻译，恳求能人相助

Question

首先说明，这段英文说的是一个研究实验的内容，“In the first study,they gave two pieces of chololate to each student.One piece was eaten when another person also ate a piece.The second piece was eaten when that other person was present but working on something else."你要做的就是翻译一下本段文字，最好能简述一下其中内涵，由于这第二个要求，我再补充一点这个实验的结论：shared experiences may feel stronger,whether they're good or bad.有条件的话可以看一下原文《Is Sharing bad for you？》
对了，还有一段文字可以帮助理解：The two pieces were from the same bar.But when researchers asked,"Which piece tasted better?"the students chose the first piece.(不好意思，麻烦你们也翻译一下这段话第一句

Answer 1

In the first study,they gave two pieces of chololate to each student.One piece was eaten when another person also ate a piece.The second piece was eaten when that other person was present but working on something else.

在第一项研究中，研究人员发给二个学生各二块巧克力。第一块吃的时候别人也在吃，第二块吃的时候有别人在场干别的事。

The two pieces were from the same bar.But when researchers asked,"Which piece tasted better?"the students chose the first piece

这二块巧克力来自同一个巧克力棒，但研究人员问那块巧克力更好吃时，二个学生都说第一块好吃
