问题 The results of the new study are unexpected.
All those people who took part in the study received vitamins and minerals.
选项 A、Right
B、Wrong
C、Not Mentioned
答案B
解析 问题句：所有参加研究的人都服用维他命和矿物质。确认线索词：vitamins and minerals，因为它们是该句的核心词。
   答案相关句：
   and minerals daily．The amounts of the vitamins and minerals were 1 to 2 times greater than what American health officials say is needed．The eighth group received sugar pills that had no effect.原文说：“研究对象有8组，其中7组每天服用维生素和矿物质，而第8组服用的是对健康没有影响的糖丸”，因此可见“不是所有的研究对象都服用维他命和矿物质”，所以问题句的说法错误。
