premise: smokers can choose how much N in a pack of cigarettes they want
fact: smokers who smoke one pack of cigarettes per day are identical in the the levels of N found in the blood
Q:explain
prephrase: the level of N in blood has a upper limit

(A) Blood cannot absorb more nicotine per day
than that found in the smoke from a package
of the lowest-nicotine cigarettes available.-----correct; 每包最低含量的N都不能被完全吸收，有一个上限，因此解释了为什么吸烟者血液中N数量都一样，因为不超过最低N含量，MAX<=the lowest
(B) Smokers of the lowest-nicotine cigarettes
available generally smoke more cigarettes
per day than smokers of high-nicotine
cigarettes.-------不能解释为什么一样，N=含量* 数量，因为这里我们不知道，数量跟含量的具体关系，文章中只讨论了吸一包烟的情况，i因此该选项out of scope
(C) Most nicotine is absorbed into the blood of a
smoker even if it is delivered in smaller
is discontinued, the level of nicotine in the
blood decreases steadily.-------该选项说的是为什么N 在血液中含量高，无关
(D) The level of tar in cigarettes is higher in low-nicotine cigarettes than it is in some high-nicotine cigarettes.---------tar无关，out of scope
(E) When taking in nicotine by smoking cigarettes
is discontinued, the level of nicotine in the
blood decreases steadily.-------没有解释为什么一样，反而说明了为什么不同，解释的是N 吸收减少的情况，而不是解释不同种类相同数量的烟为什么血液中N数量一样
