The use of automobile safety seats by children aged 4 and under has
nearly doubled in the past 8 years. It is clear that this increase has prevented child fatalities that otherwise would have occurred, because although the number of children aged 4 and under who were killed while riding in cars involved in accidents
rose 10 percent over the past 8 years, the total number of serious automobile accidents
rose by 20 percent during that period.
Which one of the following, if true, most strengthens the argument?
(A)
Some of the automobile safety seats purchased for children under 4
continue to be used after the child reaches the age of 5. - WRONG. Irrelevant.
(B) The
proportion of serious automobile accidents involving child passengers has
remained constant over the past 8 years. - CORRECT. Only then the claim of increase of child fatalities having increased would make sense.
(C)
Children are taking more trips in cars today than they were 8 years ago, but the average total time they spend in cars has remained constant. - WRONG. Goes against and thus weakens.
(D) The
sharpest increase in the use of automobile safety seats over the past 8 years has been for children over the age of 2. - WRONG. Irrelevant.
(E) The number of
fatalities among adults involved in automobile accidents rose by 10 percent over the past 8 years. - WRONG. Irrelevant.
Answer B.
