Eva: A "smart highway" system should be installed, one that would monitor area wide traffic patterns and communicate with computers in vehicles or with programmable highway signs to give drivers information about traffic congestion and alternate routes. Such a system, we can infer, would result in improved traffic flow in and around cities that would do more than improve drivers' tempers; it would decrease the considerable loss of money and productivity that now results from traffic congestion. Lines: There are already traffic reports on the radio. Why would a "smart highway" system be any better?
8. Eva's argument depends on the assumption that
(A) on "smart highways" there would not be the breakdowns of vehicles that currently cause traffic congestion
(B) traffic lights, if coordinated by the system, would assure a free flow of traffic
(C) traffic flow in and around cities is not now so congested that significant improvement is impossible
(D) the type of equipment used in "smart highway" systems would vary from one city to another
(E) older vehicles could not be fitted with equipment to receive signals sent by a "smart highway" system
Answer is C. Why?

11. Raising the tax rate on essential goods-a traditional means of increasing government revenues-invariably turns low-and middle-income taxpayers against the government. Hence government officials have proposed adding a new tax on purchases of luxury items such as yachts, private planes, jewels, and furs. The officials in government revenues while affecting only the wealthy individuals and corporations who can afford to purchase such items.
The answer to which one of the following questions would be most relevant in evaluating the accuracy of the government officials' prediction?
(A) Will luxury goods be taxed at a higher rate than that at which essential goods are currently taxed?
(B) Will be revenues generated by the proposed tax be comparable to those that are currently being generated by taxes on essential goods?
(C) Will sales of the luxury items subject to the proposed tax occur at current rates once the proposed tax on luxury items has been passed?
(D) Will the proposed tax on luxury items win support for the government in the eyes of low-and middle-income taxpayers?
(E) Will purchases of luxury items by corporations account for more of the revenue generated by the proposed tax than will purchases of luxury items by wealthy individuals?
Answer is C. Why? I think D is good.
Thanks! |
