CR 1 Mayor: the commuters from the nearby suburb of Coldstream perennially complain of a difficult commute to our downtown region. To address these concerns, we should install high-speed toll collector on the interstate between here and Coldstream, thus relieving any traffic snarls caused by the hand-operated toll booths.
Civil engineer: Over 95% of commuters from Coldstream take local roads, not the interstate, to our downtown region.
The civil engineer uses which of the following techniques in responding to the mayor?
(A) pointing out that the premise could lead to an opposing conclusion
(B) questioning whether the methods recommended would work in practice
(C) citing evidence that calls into question the assumption of the argument
(D) suggesting, by analogy, that the argument might not support the conclusion
(E) presenting evidence that the proposed solution would have damaging unforeseen consequences

CR 2 A government agency released results showing that the average lead content in many wines sold in the U.S. exceeds the Federal government's standard for drinking water. According to the results, domestically produced wines tested in the bottle often had lead contents lower than the amount allowed for drinking water; however, when the wines were poured, both domestic and imported wines contained lead levels higher than the standard for drinking water. Italian wines were found to contain some of the highest lead levels.
Which of the following, if true, contributes most to an explanation of the increase in the lead levels of domestically produced wines?
A. Pipes soldered with lead are often used in the wine production process.
B. The grapes used to make wine are often exposed to the automobile exhaust produced by leaded gasoline.
C. Leaky corks may allow the wines to react with the lead foil caps commonly used to cover the corks.
D. Deposits from the lead foil caps commonly used to cover corks may accumulate on the lips of the bottles.
E. Domestic wineries often use contaminated ground water in the wine production process.
