Test D 麻煩各位了

7.The postal service is badly mismanaged. Forty years ago, first-class letter delivery cost only three cents. Since then, the price has increased nearly tenfold, with an actual decrease in the speed and reliability of service.
Each of the following statements, if true, would tend to weaken the argument above EXCEPT:
(A) The volume of mail handled by the postal service has increased dramatically over the last forty years.
(B) Unprecedented increases in the cost of fuel for trucks and planes have put severe upward pressures on postal delivery costs.
(C) Private delivery services usually charge more than does the postal service for comparable delivery charges.
(D) The average delivery time for a first-class letter four decades ago was actually slightly longer than it is today.
(E) The average level of consumer prices overall has increased more than 300 percent over the last forty years.

Key (E)

我選C 不懂為什麼答案是E 消費物價變高不就weaken這個statement了嗎?


11.Gloria: Those who advocate tuition tax credits for parents whose children attend private schools maintain that people making no use of a government service should not be forced to pay for it. Yet those who choose to buy bottled water rather than drink water from the local supply are not therefore exempt from paying taxes to maintain the local water supply.
Roger: Your argument is illogical. Children are required by law to attend school. Since school attendance is a matter not of choice, but of legal requirement, it is unfair for the government to force some parents to pay for it twice.
Which of the following responses by Gloria would best refute Roger’s charge that her argument is illogical?
(A) Although drinking water is not required by law, it is necessary for all people, and therefore my analogy is appropriate.
(B) Those who can afford the tuition at a high-priced private school can well bear the same tax burden as those whose children attend public schools.
(C) If tuition tax credits are granted, the tax burden on parents who choose public schools will rise to an intolerable level.
(D) The law does not say that parents must send their children to private schools, only that the children must attend some kind of school, whether public or private.
(E) Both bottled water and private schools are luxury items, and it is unfair that some citizens should be able to afford them while others cannot.
