B、The one percent fall in cigarette sales in the year prior to tax increase was due to a smaller tax increase.

The inside dimensions of a rectangular wooden box are 6 inches by 8 inches by 10 inches. A cylindrical canister is to be placed inside the box so that it stands upright when the closed box rests on one of its six faces. Of all such canisters that could be used, what is the radius, in inches, of the one that has maximum volume?
老师，我选了A（半径为3）。我的理解是，如果圆柱高为10，它的底面对应长方体6*8那个面，这时候如果圆柱底面半径为4，直径是8，那就会超出长方体6英寸的边界，这个圆柱就塞不进长方体里了。麻烦老师指点一下我这个想法的问题，谢谢！

我想请tina老师解答一下，这一题ab选项后半部分的more than的差别，我看og对b的解释是more than应该后面应该立刻跟着5 a barrel，不是很明白这一点。因为我觉得b选项“refiners付5刀一桶油比他们去年给得多”，这样理解也说得通，请老师解答~
