答案

The MBA may open doors and command a higher salary initially but the impact of a degree washes out after five years.原文的意思是：工商管理硕士一开始可能会容易就业,会获得高薪,但是学位的影响力在5年之后就消失殆尽了.
问题是：说"but the impact of a degree washes out after five years"这句话,作者想表达：
A,大部分工商管理硕士课程都没有给学生们打下坚实的基础；（原文没有提及）
B,工商管理硕士的学位并不能帮助升职到管理层；（原文意思是学位刚开始的时候有影响力,但是慢慢就没什么影响力了,这个选项应该是四个里面最接近的吧）
C,工商管理硕士课程在5年之后就不会像现在这么流行了；（原文没有这么说）
D,5年后,人们就会忘记工商管硕士毕业生们拿到的硕士学位.（这样理解有误差）
所以,答案应该是B
