Until recently, most automobile manufacturers minimized the weight of their cars to maximize mileage. The safest chassis were heavy, so few manufacturers equipped their cars with the safest chassis. This year the chassis metal that has sold best to automobile manufacturers has been the safest one-a clear indication that manufacturers are assigning a higher priority to safety than to mileage.
Which of the following, if true, most seriously weakens the argument above?
  • a)
    Last year's best-selling chassis metal was not the safest chassis metal on the market.
  • b)
    No automobile manufacturer has announced that it would be making safe chassis a higher priority this year.
  • c)
    The price of gas was higher this year than it had been in most of the years when the safest chassis sold poorly.
  • d)
    Because of increases in the cost of materials, all car chassis were more expensive to manufacture this year than in any previous year
  • e)
    Because of technological innovations, the safest chassis on the market this year weighed less than some other chassis on the market.
Correct answer is option 'E'. Can you explain this answer?

The conclusion is based on an assumption that the safest chassis are still the heaviest ones, as they have been in the past. Choice E proves this assumption to be erroneous.
The CEO of Black’s International has proposed replacing their Marmacil semiconductor manufacturing equipment with Fasttech equipment since it costs 30 percent less to train new staff on the Fasttech equipment. Those opposed to the change have pointed out the savings in training cost does not justify the change. Instead, they suggested that the company hire only people who already know how to use the Marmacil equipment.
