78.(24029-!-item-!-188;#058&000661)  为什么C有关呢？这些人存了很快又拿出来了，还是没有提高长期的存款的比例呀？？


To improve the long-term savings rate of the citizens of Levaska, the country's legislature decided to implement a plan that allows investors to save up to $1,000 per year in special accounts without paying taxes on the interest earned unless withdrawals are made before the investor reaches age sixty-five.  Withdrawals from these accounts prior to age sixty-five would result in the investor's having to pay taxes on all the accumulated interest at the time of withdrawal.

Which of the following, if true, most strongly supports the prediction that the legislature's plan will have its intended effect?

A. The money saved in the tax-free savings accounts will be deposited primarily in those banks and financial institutions that supported the legislation instituting the plan.

B. The majority of people choosing to take advantage of the tax-free savings accounts will withdraw their money prior to age sixty-five.

C. A significant number of the citizens of Levaska will invest in the tax-free savings accounts well before they reach the age of sixty-five.

D. During the ten years prior to implementation of the plan, Levaskans deposited an increasingly smaller percentage of their annual income in long-term savings accounts.

E. People who are not citizens of Levaska are not eligible to invest in the tax-free savings accounts, even if their income is taxable in Levaska.

92.    (24787-!-item-!-188;#058&001210)    (GWD-3-Q38) 此题为何选A呢？Baltimore oriole和 warbler没有关系呀??

Kate:  The recent decline in numbers of the Tennessee warbler, a North American songbird that migrates each fall to coffee plantations in South America, is due to the elimination of the dense tree cover that formerly was a feature of most South American coffee plantations.
Scott:  The population of the spruce budworm, the warbler's favorite prey in North America, has been dropping.  This is a more likely explanation of the warbler's decline.
Which of the following, if true, most seriously calls Scott's hypothesis into question?
A. The numbers of the Baltimore oriole, a songbird that does not eat budworms but is as dependent on South American coffee plantations as is the Tennessee warbler, are declining.
B. The spruce budworm population has dropped because of a disease that can infect budworms but not Tennessee warblers.
C. The drop in the population of the spruce budworm is expected to be only temporary.
D. Many Tennessee warblers have begun migrating in the fall to places other than traditional coffee plantations.
E. Although many North American songbirds have declined in numbers, no other species has experienced as great a decline as has the Tennessee warbler.
