This lead 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.
正确答案是E，但感觉这个也可以weaken. 求解释。。？
2、Letter to the editor: After Baerton's factory closed, there was a sharp increase in the number of claims filed for job-related injury compensation by the factory's former employees. Hence there is reason to believe that most of those who filed for compensation after the factory closed were just out to gain benefits they didn't deserve, and filed only to help them weather their job loss.
Each of the following, if true, weakens the argument above except:
A. Workers cannot file for compensation for many job-related injuries, such as hearing loss from factory noise, until they have left the job.
B. In the years before the factory closed, the factory's managers dismissed several employees who had filed injury claims.
C. Most workers who receive an injury on the job file for compensation on the day they suffer the injury.
D. Workers who incur partial disabilities due to injuries on the job often do not file for compensation because they would have to stop working to receive compensation but cannot afford to live on that compensation alone.
E. Workers who are aware that they will soon be laid off from a job often become depressed, making them more prone to job-related injuries.
