A large apartment building in a city was assessed by a city environmental bureau for the comparatively high consumption of electricity in the building, and the landlord was threatened with a possible fine if the consumption does not drop significantly in a specified period. While all built-in appliances and lighting in common areas is energy efficient, the landlord found, upon doing an inspection, many residents were using older portable heaters that are not very energy efficient. Many residents had a few of these heaters in different rooms of the apartment. The building is often chilly, as the central heating system is old and in need of an upgrade, which will be tremendously expensive for the landlord. The landlord decided to send each resident a detailed letter about the electric energy consumption of these older portable heaters, recommending newer more energy efficient models that could be purchased at local stores. The landlord hopes that enough residents will be motivated by this letter to buy the more energy efficient heaters, so that he can avoid the fine.

Which of the following, if true, would provide most support for the prediction that the landlord's letter will have its intended effect?


(A) Residents pay for their own monthly electrical use, and the rates in this city are high, so consuming less electricity would result in a sizable monthly savings.

(B) Those apartments in the building with southern exposure get abundant sunlight, which has a substantial warming effect, and many of those residents do not use portable heaters.

(C) Some cooking appliances, like a toaster or a waffle iron, consume considerably more electricity than a portable heater during the time they are operating.

(D) Throughout the city, this same environmental agency threatened other landlord and business owners with fines for various reasons, and in almost every case, the concerned parties were able to make sufficient changes to avoid the fines.

(E) This landlord owns six apartment buildings of varying sizes in the city, and at each of the other five, the average electrical consumption is at or below the city-wide average for buildings of that size.

Conclusion:-

The landlord hopes that enough residents will be motivated by this letter to buy the more energy efficient heaters, so that he can avoid the fine.

People who are already using the old heaters (maybe the new heaters) economically (due to high electricity rates) will not purchase new heaters.

Clearcut (A)

support for the prediction that the landlord's letter will have its intended effect? Strengthen

A) Residents pay for their own monthly electrical use, and the rates in this city are high, so consuming less electricity would result in a sizable monthly savings.
(This says that residents would like save their money when have to pay high and the letter may resolve the issue.)

B) Those apartments in the building with southern exposure get abundant sunlight, which has a substantial warming effect, and many of those residents do not use portable heaters.
(this letter is regarding people who do use portable heaters not who dont)

C) Some cooking appliances, like a toaster or a waffle iron, consume considerably more electricity than a portable heater during the time they are operating.
(We are told all appliances except portable heater are energy efficient. So we are not bothered regarding them.)

D) Throughout the city, this same environmental agency threatened other landlords and business owners with fines for various reasons, and in almost every case, the concerned parties were able to make sufficient changes to avoid the fines.
(what other parties were able may not apply here and various reasons cannot be the same. Even if it is so it just indicates a possibility of success and is a very weak strengthener.)

E) This landlord owns six apartment buildings of varying sizes in the city, and at each of the other five, the average electrical consumption is at or below the citywide average for buildings of that size.
(This info does least amount of help. OFS)

Hello,

Just a short note to already provided very nice explanation by MechMeera.

Argument suggests that "landlord hopes the letter will motivate enough residents to buy more energy efficient heaters"

Now what additional fact would augment the landlords claim?

Well, if residents are paying for their electricity bills then it is sufficient incentive to save money. On the other hand if the Landlord himself is paying electricity bill (unlikely though) then the residents would not have sufficient incentive to buy new heaters and save electricity.

Official Explanation


The credited answer is (A). If residents find out the heaters they are user will cost them more money, via their own electrical bills, then they will be motivated to replace their old heaters with more energy-efficient models, thus lowering the overall electrical consumption of the building --- the landlord's goal.

The fact that some apartments get sunlight and don't need heaters doesn't alter the fact that many others do use the heaters. The information supplied by the landlord will be more or less irrelevant to the folks who don't use heaters. Choice (B) is incorrect.

Choice (C) indicates another potential drain on energy, but that would involve a separate plan: it doesn't directly support the landlord's plan. Choice (C) is incorrect.

The fact that other landlords, doing whatever they did, avoided the fine does not necessarily tell us whether the landlord of this particular building will be successful. Choice (D) is incorrect.

The other buildings operated by this landlord don't have this problem, but this doesn't tell us how the landlord will handle the problem where it does exist. Choice (E) is incorrect.
