The temperature in Taychester is always at least 10 degrees lower than the temperature in Charlesville. However, the average resident of Charlesville spends 10 to 20 percent more on winter heating expenses than does the average resident of Taychester.
Each of the following, if true, helps to resolve the apparent paradox described above EXCEPT:The paradox is that Charlesville is warmer, yet its residents spend more on heating.
We need the choice that does not help explain why heating costs are higher in the warmer city.(A) Heat loss due to wind is less in Taychester than in Charlesville.
Explains the paradox. If Charlesville loses more heat because of wind, residents there may need to spend more on heating despite the warmer temperatures.
(B) Although Charlesville is always fairly warm during the daytime, temperatures in Charlesville drop steeply at night.
Explains the paradox. Very cold nights could increase heating use enough to raise overall winter heating expenses.
(C) Utility rates in Taychester are lower than utility rates in Charlesville.
Explains the paradox. Even if Taychester residents use more heat, lower utility rates could make their total heating expenses lower.
(D) People who are used to warmer temperatures generally keep their homes warmer in the winter than do people who are used to colder temperatures.
Explains the paradox. Charlesville residents may maintain higher indoor temperatures and therefore spend more on heating.
(E) Houses in colder climates are usually better insulated than houses in warmer climates.
Explains the paradox. If Taychester homes are better insulated, they may require less energy to stay warm despite the colder climate.
Answer: (B)
