A provincial government has proposed an increase in the taxes imposed on cigarettes to give people an incentive to smoke less, or leave smoking altogether. However, skeptics point out that most people in the province live in areas where smoking starts as a medium to socialize with classmates in high school and later becomes a habit. Therefore, smoking habits cannot be greatly changed in response to higher cigarette prices.

In light of the skeptics' objection, which of the following, if true would most logically support the prediction that the government's plan will achieve its goal of reducing smoking?

A. The rise in cigarette prices will reduce socializing over cigarette and increase consumption of alcohol.
B. The tax will encourage many people to switch to loose tobacco, on which the tax has not been increased.
C. Because cigarettes have been subsidized for restaurants, the province has many restaurants where only cigarettes are available.
D. Most residents who cannot change their smoking habits could compensate for high cigarette prices by reducing expenditure on fuel for their cars; they would travel by train.
E. Second hand smoke is an especially serious problem that often leads to lung problems, for people who live with smokers.

The OA is A.

How should I think on this exercise? What could be a good plan?
