Editorial:Our city's public transportation agency is facing a budget shortfall. The fastest growing part of the budget has been employee retirement benefits, which are exceptionally generous. Unless the budget shortfall is resolved, transportation service will be cut, and many transportation employees will lose their jobs. Thus, it would be in the employees' best interest for their union to accept cuts in retirement benefits.
Which of the following is an assumption the editorial's argument requires?
The transportation employees' union should not accept cuts in retirement benefits if doing so would not be in the employees' best interest.
The only feasible way for the agency to resolve the budget shortfall would involve cutting transportation service and eliminating jobs.
Other things being equal, it is in the transportation employees' interest to have exceptionally generous retirement benefits.
Cutting the retirement benefits would help resolve the agency's budget shortfall.
The transportation employees' union will not accept cuts in retirement benefits if doing so will not allow more transportation employees to keep their jobs.
情景：Editorial：交通部门缺钱，预算的主要来源是雇员的退休金。所以，除非预算短缺解决了，交通部门就得减少服务并且裁员。因此，雇员工会最好接受“缩减退休金”这一选项。
推理：可以近似看为一个方案推理。
目标：解决budget shortfall
方案：缩减退休金
选项分析：
A选项：如果缩减退休金不符合雇员工会的利益，那么就不要接受这一条件：这与“缩减退休金能不能解决预算短缺”无关。
B选项：解决预算短缺的唯一方法是减少运输服务并且裁员：取非后，减少服务和裁员不是唯一方法，这与“缩减退休金能不能解决预算短缺”无关。
C选项：其他不变，有巨额退休金符合雇员的利益：无关。
D选项：正确。缩减退休金会解决预算短缺：取非后，缩减退休金不会解决预算短缺——直接指出方案不可行，目的达不到。
E选项：如果缩减退休金不会使得更多的雇员保住饭碗，那么工会就不会接受这个条件：无关。
方案推理，取非
