Tenants who do not have to pay their own electricity bills do not have a financial incentive to conserve electricity. Thus, if more landlords install individual electricity meters on tenant dwellings so that tenants can be billed for their own use, energy will be conserved as a result.The conclusion of the argument is the following:
if more landlords install individual electricity meters on tenant dwellings so that tenants can be billed for their own use, energy will be conserved as a resultThe support for the conclusion is the following:
Tenants who do not have to pay their own electricity bills do not have a financial incentive to conserve electricity.We see that the reasoning of the argument is basically that, since installing meters will result in tenants having an incentive to conserve electricity, installing meters will result in a decrease in electricity use.
Which one of the following, if true, most weakens the argument?This is a Weaken question, and the correct answer will show that, even though the evidence is true, the conclusion may not be.
(A) Tenants who do not have to pay their own electricity bills generally must compensate by paying more in rent.This choice is tempting because it indicates that tenants do in a way pay for their own electricity. So, it could seem to conflict with the idea that tenants do not have to pay their own electricity bills and thus somehow weaken the argument.
The issue is that indirectly paying for electricty by "paying more in rent" and paying "their own electricity bills" are two different things.
When a landlord charges more in rent to cover electricity expenses, typically the tenant pays the same amount of rent regardless of how much electricity is used. Thus, under such an arrangement, the cost to the tenant remains the same regardless of how much electricity the tenant uses. So, tenants who have to pay more in rent to cover electricity expenses do not "have a financial incentive to conserve electricity."
So, even if this choice is true, it could still be the case that, if more landlords install individual electricity meters on tenant dwellings, energy will be conserved as a result. After all, installing meters will still result in tenants having a financial incentive to conserve electricity that they don't currently have.
Thus, this choice does not weaken the case for the conclusion.
Eliminate.
(B) Many initiatives have been implemented to educate people about how much money they can save through energy conservation.This choice strengthens, rather than weakens the argument.
After all, it provides reason to believe that people understand that they can save money by conserving energy and thus provides additional reason to believe that, if tenants are paying their own electricty biils, they will conserve energy to save money.
Eliminate.
(C) Landlords who pay for their tenants' electricity have a strong inventive to make sure that the appliances they provide for their tenants are energy efficient.This choice is interesting.
The reasoning of the argument is basically that giving tenants incentives to conserve electricity will result in energy conservation.
This choice shows that there's a factor that the argument does not take into account: Giving the incentive to conserve to tenants may take it away from landlords.
According to this choice, when landlords pay the bill, they have an incentive to conserve energy by providing appliances that are energy efficient. So, having tenants pay the bill instead will cause landlords not to have that incentive, in which case they may not provide energy-efficient appliances.
In that case, even though tenants may conserve electricity, energy may not be conserved more than it would be if landlords were paying the bill since the appliances used by tenants may be less energy efficient than they would be if landlords had an incentive to provide efficient appliances.
So, this choice shows that, even though installing meters would give tenants an incentive to conserve energy, it may not cause additional energy to be conserved.
Keep.
(D) Some tenant dwellings can only support individual electricity meters if the dwellings are rewired, which would be prohibitively expensive.This choice weakens the case for the wrong conclusion.
The choice indicates that, in some cases, installing meters would not be practical and thus weakens the case for the conclusion that all landlords are likely to install meters.
In contrast, the conclusion we need to weaken the case for is that installation of meters, IF DONE, will serve to conserve energy.
In short, the conclusion we need to weaken the case for is about the EFFECT of installing meters, whereas this choice indicates that the LIKELIHOOD that meters will be installed is low, in some cases.
Eliminate.
(E) Some people conserve energy for reasons that are not related to cost savings.This choice is about "some people."
Even if
some people conserve energy without paying their own electricity bills, it could still be the case that
other people will conserve more energy if they have to pay their own electricity bills.
So, even if this choice is true, the argument works.
Eliminate.
