问题 Bernie has already read 1/5 of his biology homework on Monday night. What fraction of his remaining homework would Bernie have to read on Tuesday night in order to have read 2/3 of his original biology assignment?

选项 A、7/10
B、7/12
C、2/15
D、2/3
E、1/15

答案 B

解析本题的关键在于考生读题时需要注意what fraction of his remaining homework，问题问的是剩下作业的几分之几，而不是所有作业的几分之几。所以分母不是1，而是剩下的4/5作业，

。
