狒狒26. Barnes: The two newest employees at this company have salaries that are too high for the simple tasks normally assigned to new employees and duties that are too complex for inexperienced workers. Hence, the salaries and the complexity of the duties of these two newest employees should be reduced.
Which one of the following is an assumption on which Barnes’s argument depends?
(A) The duties of the two newest employees are not less complex than any others in the company.
(B) It is because of the complex duties assigned that the two newest employees are being paid more than is usually paid to newly hired employees.
(C) The two newest employees are not experienced at their occupations.
(D) Barnes was not hired at a higher-than-average starting salary.
(E) The salaries of the two newest are no higher than the salaries that other companies pay for workers with a similar level of experience.

请问B错在哪儿？个人感觉是和unusally paid无关，因此是无关选项。但是狒狒详解说是“B: 这似乎在为两个新雇员拿高工资找理由，所以不能支持结论。"，这个解释看不懂啊~
请牛人帮忙解释~~谢谢啦

Necessary assumption. Use negation.

If you negate B, you have:
It is NOT because of the complex duties assigned that the two newest employees are being paid more than is usually paid to newly hired employees. If this is the case, we might still reduce the starting salaries for the newcomers. So the conclusion still hold. Thus, B is not a necessary condition for the argument.

If you negate C, you will make the argument fall apart.
