A、During the year following the tax increase, the pretax price of a pack of cigarettes did not increase by as much as it had during the year prior to the tax increase.
B、The one percent fall in cigarette sales in the year prior to tax increase was due to a smaller tax increase.

D、For the year following the tax increase, the pretax price of a pack of cigarettes was not eight or more cents lower than it had been the previous year.

A rectangular bar of length 20 feet and width 6 inches. A vertical divides the rectangle into 2 parts. This line meets the base of the rectangle at point B. The left section of the rectangle has a right inclined line from a point A on the base. It forms an angle x degrees above the base of the rectangle at point A. The right section of the rectangle has a right inclined line from a point C on the base. It forms an angle x degrees above the base of the rectangle at point C.

The figure above shows the dimensions of a rectangular board that is to be cut into four identical pieces by making cuts at points A, B, and C, as indicated. If x = 45, what is the length AB ?

Economist: The most economically efficient way to reduce emissions of air pollutants is to tax them in proportion to the damage they are likely to cause. But in Country Y, many serious pollutants are untaxed and unregulated, and policy makers strongly oppose new taxes. Therefore, the best way to achieve a reduction in air pollutant emissions in Country Y would be to institute fixed upper limits on them.

Which of the following is an assumption of the economist’s argument?
A为什么不对呀?取非的话,有benefits的时候policy maker不反对tax,不久可以加强tax的可实行性吗?这样的话tax不就还是最efficient的吗?这道题的的P是policy maker反对tax C是limits最有效 我找的是对的嘛,谢谢老师的解
