In Australia, the population that is of driving age has grown large over the last five years, but the annual number of traffic fatalities has declined. This leads to the conclusion that, overall, the driving-age population of Australia consists of more skillful drivers now than five years ago.
Each of the statements below, if true, weakens the argument EXCEPT:
(A) Three years ago, a mandatory seat-belt law went into effect throughout Australia.
(B) Five years ago, Australia began a major road repair project.
(C) Because of increases in the price of fuel, Australians on average drive less each year than in the preceding year.
(D) The number of hospital emergency facilities in Australia has doubled in the last five years.
(E) In response to an increase in traffic fatalities, Australia instituted a program of mandatory driver education five years ago.
Premise: The population that is of driving age has grown large over the last five years, but the annual number of traffic fatalities has declined
Conclusion: The decline is because of skillful drivers.
(A) Three years ago, a mandatory seat-belt law went into effect throughout Australia. - This MAY provide an alternate reason for the reduction in number of accidents.
(B) Five years ago, Australia began a major road repair project. - Hold
(C) Because of increases in the price of fuel, Australians on average drive less each year than in the preceding year. - This weakens by giving an alternate reason for reduction in no of accidents.
(D) The number of hospital emergency facilities in Australia has doubled in the last five years. This MAY weaken the argument. What if the no.of accidents have increased and because of the increase in emergency facilities, the fatalities have decreased?
(E) In response to an increase in traffic fatalities, Australia instituted a program of mandatory driver education five years ago. Hold
Between B and E, E seems to strengthen the argument by saying it MAY be because of the driver's efforts, the number of accidents are reducing. I'll go with E.
Cheers!
