GMAT Critical Reasoning
Motorists in a certain country frequently complain that traffic congestion is much worse now than it was 20 years ago. No real measure of how much traffic congestion there was 20 years ago exists, but the motorists' complaints are almost certainly unwarranted. The country's highway capacity has tripled in the last twenty years, thanks to a vigorous highway construction program, whereas the number of automobiles registered in the country has increased by only 75 percent.
Which of the following, if true, most seriously weakens the argument?
- A Most automobile travel is local, and the networks of roads and streets in the country's settled areas have changed little over the last 20 years.
- B Gasoline prices are high, and miles traveled per car per year have not changed much over the last 20 years.
- C The country's urban centers have well-developed public transit systems that carry most of the people who commute into those centers.
- D The average age of automobiles registered in the country is lower now than it was 20 years ago.
- E Radio stations have long been broadcasting regular traffic reports that inform motorists about traffic congestion.
