Can you please explain why B ic correct? If the temperature in Charlesville drops at night, wouldn't that explain why average residents of Charlesville spends 10 to 20 percent more on winter heating expenses than the average resident of Taychester?

@Sidra,

(B) does not help because we are talking about relative temperatures, and the stimulus tells us that "the temperature in T is always at least 10 degrees lower than in C", so even if temperatures in C drop steeply at night, T is still 10 degrees colder than C, so why are C residents paying more for heating than C? Also, night temperatures are irrelevant to winter heating expenses.

Let me know if you have any further questions.
