研究人员对每项工作都进行了定价,想要知道一般人花费多少时间来做它们(指工作).
the在这里表特指,如果换成a应该也是可以的
后面是一个句型:sb.takes sometime doing sth
你将它改为特殊疑问句,以How long开头,便是:How long does sb. take doing sth?
因为该句子做宾语从句,所以必须用陈述语序,便是:How long sb. takes doing sth

研究人员为每个零工定价,然后试图找出平均每个人花多长时间去完成。
average 前面要加也是加an的,不是a,跟the其实效果是一样的
take 是相对于the average person来说的,how long the average person takes// doing them,断句要断准,不是take doing 的句型啦。

研究人员为每个日常零星工作
标价,然后试图找出平均每个人花多长时间去完成.average person前面的冠词是the表示不是指具象的某个人,而是泛指概念.句型SB TAKE SOME TIME (IN) DOING STH,是一个句型,表示花时间一直在做某事,IN可以省略.

研究者把价格在每件苦差事,然后试图找出一般人需要多长时间从事此类工作
特指
take doing sb.

研究人员对每个零工定价,然后试图找出人们完成平均所需时长.
