Mall owner: Our mall's occupancy rate is so low that we are barely making a profit. We cannot raise rents because of an unacceptably high risk of losing established tenants. On the other hand, a mall that is fully occupied costs about as much to run as one in which a rental space here and a rental space there stands empty. Clearly, therefore, to increase profits we must sign up new tenants.
Which of the following, if true, most seriously weakens the argument?
The mall's operating costs could be cut by consolidating currently rented spaces in such a way that an entire wing of the mall could be closed up.
The mall is located in a geographic area in which costs incurred for air-conditioning in the hot summers exceed those incurred for heating in the mid winters by a wide margin.
The mall's occupancy rate, though relatively low, has been relatively stable for several years.
The mall lost tenants as a result of each of the two major rent increases that have occurred there.
None of the mall's established tenants is likely to need additional floor space there in the foreseeable future.
⚠️最后结论中提到了must 该题的目的在于削弱方案的唯一性：【must】 sign up new tenants.
choice a, 商场的运营成本（operating costs）可以通过整合现有租客（consolidating currently rented spaces）的方式来降低。（√）提出了另一个方案，削弱了方案的唯一性✅
choice e, 没有一个现有的租客在可见的未来需要额外的楼层空间。（×）增强
E: 是support了conclusion的，现有租客不喜欢周围空着，所以要找新租客
方案: find new tenants to increase profits
削弱：其他方案consolidate current spaces so the cost will decrease
A选项提出了另一个方案，削弱了方案的唯一性✅
choice a, 商场的运营成本可以通过整合现有租客的方式来降低。correct，说明增加利润不止签新租客这一个办法
choice e, 没有一个现有的租客在可见的未来需要额外的楼层空间。strengthen the conclusion
现在利润很低，要提高利润
两个方法：①cost角度②tenant角度
注意：可能有一些逻辑题提出方案之后 问削弱 选项讲到另一个方案的话就应该排除了
但是！注意理解这个题目的问法：to increase profits==》must==》sign up new tenants
所以说 sign up new tenants 是一定可以提高利润的 毋庸置疑 题目想要削弱的是这个方案的唯一性！must！
注意理解这句话的意思 以及 句子的结构
体会 the entire wing==》一整边
empty的mall和fully occupied的mall的cost是一样的
weaken--增加利润还可以通过减少成本实现，因此不一定要增加租户

如果是评估或者加强，也不能说方案的另一个好处，要找副作用的取非。到这题，怎么就变成给出另一个方案了。
除非，就是理解成这不是方案，是因果，要断掉推出这个方案的因果联系，就是我告诉你增加利润是可以减成本的，你那个说成本不变，只能提高租户的逻辑是片面的。
这样的话对么？
这道题有点不太一样，它说的是唯一的方法是balabala，weaken就可以是有其他方法了
这个题显然是不合理的登录 或 注册 后可以参加讨论
为了↑profits只有↑renting一种方法
削弱：有↓costs的方法来↑profits
