【加强题-事实找原因】46.(33987-!-item-!-188;#058&007200)
Archaeologists in Michigan have excavated a Native American camp near Dumaw Creek.Radiocarbon dating of animal bones found at the site indicates that the camp dates from sometime between 1605 and 1755.However, the camp probably dates to no later than 1630, since no European trade goods were found at the site, and European traders were active in the region from the 1620's onward.
Which of the following, if true, most strengthens the argument?
(A) Due to trade among Native Americans, some European trade goods would have reached the area before the European traders themselves did.
(B) At all camps in the region that have been reliably dated to the late 1620's, remains of European trade goods have been found.
欧洲贸易物品的残骸在该地区所有被确认为1620年左右的帐篷附近被找到。
可它是个Native American Camp啊。。。
(C) The first European trade goods to reach the area would have been considered especially valuable and preserved as much as possible from loss or destruction.
(D) The first European traders in the area followed soon after the first European explorers.
(E) The site is that of a temporary camp that would have been used seasonally for a few years and then abandoned.
我屡不清这道题的逻辑关系，而且越看越不知道它问的到底是什么意思。。。
【论证方法题】66.(35089-!-item-!-188;#058&007596)
Bank depositors in the United States are all financially protected against bank failure because the government insures all individuals' bank deposits.An economist argues that this insurance is partly responsible for the high rate of bank failures, since it removes from depositors any financial incentive to find out whether the bank that holds their money is secure against failure.If depositors were more selective, then banks would need to be secure in order to compete for depositors' money.
The economist's argument makes which of the following assumptions?
美国的银行储户在银行倒闭问题上，全部都在经济上受保护，因为政府要保证所有个人的银行存款。
一位经济学家表明这种保证实际上要对银行倒闭率较高的现象负担部分责任。因为这种保证会出去任何储户的经济奖励，为的是找到是否持有他们钱的银行远离倒闭的危险。
如果储户能够有更好的选择性，那么银行就需要被迫增加保证来互相竞争储户的钱。
(A) Bank failures are caused when big borrowers default on loan repayments.
(B) A significant proportion of depositors maintain accounts at several different banks.
(C) The more a depositor has to deposit, the more careful he or she tends to be in selecting a bank.
(D) The difference in the interest rates paid to depositors by different banks is not a significant factor in bank failures.
(E) Potential depositors are able to determine which banks are secure against failure.
