答：2012年职称英语理工类教材新增内容详解——完形填空篇1
Vriesekoop is a microbiologist at the University of Ballarat in Australia．He led the study,which compared the germ populations found on money __6__ from 10 nations．The scientists studied 1,280 banknotes in total; all came from places where people buy food,like supermarkets,street vendors and cafes,__7__ those businesses often rely on cash.
6.A delivered B borrowed C gathered D designed
7.A because B though C when D where
6.C 上一句说 Vriesekoop 比较不同国家纸币携带病菌的数量.本题的句子明确指出他对比 的纸币涉及十个国家.四个选项中只有 gathered （收集）与上下文的意思相匹配.
7.A 填词所在的句子与前面的主句存在因果关系.为什么要从食品店和食品摊收集纸币呢?因为这些地方常要用现金支付.本题答案是 because.
回答楼主及palmaking 的问题.
楼主这题改自这个完型填空题,楼主没有打错标点,人称代词和数字的变化关系不大.这个分号=and,可以并列两个句子.like A B and C是插入语,增加了两个逗号,去掉它,就没有逗号了,because从句还是在主句之后,没有问题.
光从语法上看,这空填Where似乎也说得通,=in which 表示“在这些地方”,但问题是：从句中的those businesses指什么呢?
其实,这里的those businesses 指的就是前面的A B and C,这些生意,这些行业,这些商家.
原作者的意图在此,原文如此.because最佳.
与一帘春水讨论：
我不同意这个观点.因为定语从句应紧跟其先行词,如用where,则也可以理解其先行词就是前面的三个场所.在这三个场所里=in supermarkets,street vendors and cafes,但是,这个those businesses 就不好解释了.因为这个those businesses特指什么生意呢?不合逻辑.如改为business ,则泛指在这三个场所,生意经常要依靠现金.
而用了because之后,those bussinesses 就是指前面这三个行业,这样句子就通了.
