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.
7. The economist's argument makes which of the follow-
ing assumptions?
(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 deposi-
tors by different banks is not a significant
factor in bank failures.
(E) Potential depositors are able to determine which
banks are secure against failure.
答案：E， 我觉得D也是假设， 是属于假设中的排除他因，为什么不是答案呢？
12. Although aspirin has been proven to eliminate moder-
ate fever associated with some illnesses, many doctors
no longer routinely recommend its use for this purpose.
A moderate fever stimulates the activity of the body's
disease-fighting white blood cells and also inhibits the
growth of many strains of disease-causing bacteria.
If the statements above are true, which of the following
conclusions is most strongly supported by them?
(A) Aspirin, an effective painkiller, alleviates the pain
and discomfort of many illnesses.
(B) Aspirin can prolong a patient's illness by eliminat-
ing moderate fever helpful in fighting some
diseases.
(C) Aspirin inhibits the growth of white blood cells,
which are necessary for fighting some illnesses.
(D) The more white blood cells a patient's body
produces, the less severe the patient's illness
will be.
(E) The focus of modern medicine is on inhibiting the
growth of disease-causing bacteria within the
body.
