Motorists

Post Sat Jul 23, 2011 2:39 pm

  • Lap #[LAPCOUNT] ([LAPTIME])
    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.

    A: clearly weakens the argument and hence supports the motorists concern about increasing congestion! Hence Correct
    B: contender! as says that each car spends the same time on road, that it used to, 20 years before. Given the inc in no of cars, can assume it to weaken the arg.
    C: Supports the argument; says less cars on road!
    D: Again supports the arg. says less cars on road!
    E: in a sense supports, thus rejected.

    Looks like A only!

    IMO A

    Expansion has happened on highways whereas traffic has increased locally.
