Mall owner: Our mall's occupancy rate is so low that we are barely making a profit. We cannot raise rents because of unacceptably high risk of losing our tenants. On the other hand, a mall that is fully occupied costs as much to run as one with a rental space here and a rental space there stands empty. Clearly, therefore, to increase profits we must sign up new tenants.
The conclusion of the argument is the following:
Clearly ... to increase profits we must sign up new tenants.
The support for the conclusion is the following:
We cannot raise rents because of unacceptably high risk of losing our tenants.
and
On the other hand, a mall that is fully occupied costs as much to run as one with a rental space here and a rental space there stands empty.
We see that the reasoning of the argument is basically that, since raising rents is not an option and operating a mall with empty spaces interspersed with occupied ones costs just as much as operating a fully occupied mall, the only way to increase profits is to get new tenants.
Which of the following, if true, weakens the argument?
This is a Weaken question, and the correct answer will show that, even though the premises are true, the conclusion may not be.
(A) 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 premises of the argument are basically that increasing rents is not an option and that operating a mall with empty spaces interspersed with occupied ones costs just as much as operating a fully occupied mall.
So, this choice is interesting because it presents another option, consolidating currently rented spaces in such a way that an entire wing of the mall could be closed up.
The fact that costs could be reduced in that manner weakens the case for the conclusion. After all, in that case, even though the premises are true, it's not true that, to increase profits, the mall must get more tenants.
After all, even without more tenants, if costs are reduced, the mall should earn greater profits.
Keep.
(B) The mall is located in a geographic area where the costs for air conditioning in the summers far exceed the cost of heating during the mild winters.
Although costs and profits are related, this choice does not weaken the case for the conclusion.
After all, to weaken the argument, the correct answer must somehow indicate that it's not the case that the only way to increase profits is to sign up new tenants.
The fact that the costs for air conditioning exceed the cost of heating doesn't indicate anything about how the mall could increase profits. After all, presumably, profitable operation of the mall requires air conditioning and heating.
So, since this choice doesn't indicate that there's a way to reduce the costs of air conditioning and heating, the information provided by this choice has no effect on the strength of the argument.
Eliminate.
(C) The mall's occupancy rate though low, has been relatively stable during the last few years.
This choice mentions a positive aspect of the mall's operation: occupancy has been stable.
At the same time, the conclusion we need to cast doubt on is not that the mall's situation is all bad. It's specifically that, to increase profits, the mall must get new tenants.
The fact that the occupancy has been stable does not mean that there's any way other than getting new tenants to increase profits.
Eliminate.
(D) The mall lost tenants as a result of each of the two drastic rent increases that have occurred here.
If anything, this choice helps to confirm the premise of the argument that "we cannot raise rents."
A choice that confirms a premise of the argument is in line with, rather than weakens, the argument.
Eliminate.
(E) None of the established tenants is likely to need additional floor space in the near future.
This choice strengthens, rather than weakens, the argument.
After all, if none of the established tenants is likely to need additional floor space in the near future, then the mall cannot increase profits by renting additional floor space to established tenants.
So, this choice provides additional confirmation for the conclusion that "to increase profits, we must sign up new tenants."
Eliminate.
