关于巧克力的英文短文
Chocolate lovers know that eating chocolate makes them happy.Now it turns out that eating chocolate may also make them smarter.Dr.Bryan Raudenbush recently conducted a study to see how eating chocolate affects people's brains.The U.S.researcher knew that chocolate contained several stimulants.But he wasn't sure how those stimulants actually affected chocolate eaters.
To find out,Raudenbush had a group of volunteers eat 85 grams of milk chocolate.He asked another group to eat no chocolate at all.After 15 minutes,he tested their memory and their ability to solve problems.
The group that ate milk chocolate had higher scores.They were able to remember more words and pictures than the group that did not eat chocolate,Raudenbush concluded that the stimulants in chocolate increased mental alertness.
Of course,eating chocolate doesn't guarantee you'll pass every test.You'll still need to study!
里面有这样一道题
The result of the test is that()
A.the group that ate chocolate had higher crores than the group that did't eat
B.the stimulants in chocolate increased mental alertness
到底选哪个?
那么为何不选B呢~
因为问题问得是考试结果（ result)
而不是得出的结论 这句话好

个人认为题目的翻译应当是：这个个测试的结果是（）
test在这里指的是Dr.Bryan Raudenbush 的巧克力测试,不是“考试”的意思～
测试的结果是A,B项是测试得出的一个结论～
