Official Solution:A significant drop in the number of accidents caused by impaired driving due to cell phone use is chiefly a result of aggressive public awareness efforts on the part of the government as well as the cell phone industry itself. A new marketing campaign by a major telecommunications firm emphasizes the ways in which a cell phone should and should not be used by drivers. However, some public safety experts are concerned that this will lead drivers to become overconfident in their ability to handle both tasks and will increase the number of accidents. Which of the following, if true, would most weaken the objections that public safety experts have to the new marketing campaign?A. The number of people who use their cell phones while driving has decreased since the marketing campaign began.
B. The marketing campaign is part of an effort to increase the sales of a new type of phone that was specifically designed to be used without drivers needing to look at or touch the phone at all.
C. The drop in the number of accidents caused by impaired driving due to cell phone use is especially large among younger drivers.
D. Studies conducted by public safety experts have shown that most people are not good judges of how well they can handle cell phone use while driving.
E. Initial reports have shown that most people who have been exposed to the marketing campaign have modified their driving habits in beneficial ways.
CR Box: W. This is a weaken question, but one must be clear as to whose argument we are trying to weaken -- the public safety experts, not the author of the passage
1 BID (Boil It Down): The marketing campaign shows how drivers can use a cell phone. The marketing campaign will lead drivers to become overconfident in their ability to drive and use a cell phone, leading to more accidents.
2 Destroy the underlying reasoning Likely: Showing drivers how they can use a cell phone will NOT lead people to improperly use their phones while driving.
Choice E is correct. This directly attacks the safety experts' conclusion. If most people who have been exposed to the marketing campaign drive more safely, then those drivers will get in fewer accidents, not more.
Choice A might lead to fewer accidents, but there is no known connection to the marketing campaign. How many people have seen it and how have they responded? The campaign could still, as the experts say, lead to more accidents.
Choice B tells us that the campaign was not just about saving lives. That has no effect on the argument. It also suggests that the design of the new phones might lead to safer driving, but that doesn't tell us anything definite about the effect of the campaign.
Choice C is pure background information, and as such, has no bearing on the conclusion.
Choice D, if anything, supports the point of view of the safety experts whose opinion we are trying to weaken. If people cannot judge their own ability to drive and use a phone, then the new campaign could be a problem (though not necessarily). The main point here is that this choice does not weaken the experts' position.
