题目：

In the year following an eight-cent increase in the federal tax on a pack of cigarettes, sales of cigarettes fell ten percent.  In contrast, in the year prior to the tax increase, sales had fallen one percent.  The volume of cigarette sales is therefore strongly related to the after-tax price of a pack of cigarettes.

Historian:  Newton developed mathematical concepts and techniques that are fundamental to modern calculus.  Leibniz developed closely analogous concepts and techniques.  It has traditionally been thought that these discoveries were independent.  Researchers have, however, recently discovered notes of Leibniz' that discuss one of Newton's books on mathematics.  Several scholars have argued that since the book includes a presentation of Newton's calculus concepts and techniques, and since the notes were written before Leibniz' own development of calculus concepts and techniques, it is virtually certain that the traditional view is false.  A more cautious conclusion than this is called for, however.  Leibniz' notes are limited to early sections of Newton's book, sections that precede the ones in which Newton's calculus concepts and techniques are presented.
 
In the historian's reasoning, the two boldfaced portions play which of the following roles?
more cautious conclusion...however 然而有个更cautious的结论为什么不是表递进呢？之前老师说however有时候不一定是转折，要根据句子间的逻辑关系判断，而这里我不认为两个boldface是相反关系，请老师指点！谢谢！

Hutonian Government Official:  Federal law requires truck drivers to take a long break after driving for ten hours, but truck drivers frequently do not comply.  Since the public rest areas along our highways cannot accommodate all the drivers needing a break, we plan to build more rest areas to increase the rate of compliance.
 
Hutonian Business Representative:  But if the parking lots around our businesses are considered, there are more than enough parking places.

The symptoms that United States President Zachary Taylor began showing five days before his death are consistent with arsenic poisoning.  Recent examination of Taylor's bones, however, revealed levels of arsenic comparable to those found in the bones of Taylor's contemporaries.  These levels are much lower than the levels of arsenic that remain in the bones of arsenic poisoning victims who live for more than a day after ingesting a lethal dose of the poison.
Which of the following is most strongly supported by the statements given?
