Driving age

by selango » Wed Jul 28, 2010 11:09 am
In Australia the population that is of driving age has grown larger 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.

E is right because every other answer raises outside element that explains why fatality rate went down.

A - seat belt decreases risk of fatality.
B - road repair project improves roads - lower risk of accident
C - people simply drive less - lower risk.
D - more hospitals means improved access with less delay to medical cares.

E - actually supports the argument that lower fatality is because people drive better.
