问题 Which of the following, if true, most logically completes the argument below?
Manufacturers are now required to make all cigarette lighters child-resistant by equipping them with safety levers. But this change is unlikely to result in a significant reduction in the number of fires caused by children playing with lighters, because children given the opportunity can figure out how to work the safety levers and________.
选项 A、the addition of the safety levers has made lighters more expensive than they were before the requirement was instituted
B、adults are more likely to leave child-resistant lighters than non-child-resistant lighters in places that are accessible to children
C、many of the fires started by young children are quickly detected and extinguished by their parents
D、unlike child-resistant lighters, lighters that are not child-resistant can be operated by children as young as two years old
E、approximately 5,000 fires per year have been attributed to children playing with lighters before the safety levers were required.
答案 B
解析 Argument Construction
Situation Manufacturers must equip all cigarette lighters with child-resistant safety levers, but children can figure out how to circumvent the safety levers and thereby often start fires.
Reasoning What point would most logically complete the argument? What would make it likely that the number of fires caused by children playing with lighters would remain the same? In order for children to start fires using lighters equipped with safety levers, they must be given the opportunity to figure out how the safety levers work and then to use them. They must, that is, have access to the lighters.
A If safety-lever-equipped lighters are more expensive than lighters that are not so equipped, fewer lighters might be sold. This would most likely afford children less access to lighters, thus giving them less opportunity to start fires with them.
B Correct. This statement properly identifies a point that logically completes the argument: it explains why children are likely to have access to lighters equipped with safety levers.
C The speed with which fires are extinguished does not have any bearing on the number of fires that are started.
D This provides a reason to believe that the number of fires started by children will most likely decrease, rather than stay the same: fewer children will be able to operate the lighters, and thus fewer fires are likely to be started.
E This information about how many fires were started by children before safety levers were required does not have any bearing on the question of how many fires are likely to be started by children now that the safety levers are required.
The correct answer is B.
