PrepTest 27, Section 3, Question 4
Mayor: Citing the severity of the city's winters, the city road commissioner has suggested paving our roads with rubberized asphalt, since the pressure of passing vehicles would cause the rubber to flex, breaking up ice on roads and so making ice removal easier and less of a strain on the road-maintenance budget. However, rubberized asphalt is more expensive than plain asphalt and the city's budget for building and maintaining roads cannot be increased. Therefore, the commissioner's suggestion is not financially feasible.

Which one of the following is assumed by the mayor's argument?
Using rubberized asphalt to pave roads would not have any advantages besides facilitating the removal of ice on roads.
The severity of winters in the region in which the city is located does not vary significantly from year to year.
It would cost more to add particles of rubber to asphalt than to add particles of rubber to other materials that are used to pave roads.
Savings in the cost of ice removal would not pay for the increased expense of using rubberized asphalt to pave roads.
The techniques the city currently uses for removing ice from city roads are not the least expensive possible, given the type of road surface in place.
