有些假设题，我的确不知如何下手？ The government provides insurance for individuals? band deposits, but requires the banks to pay the premiums for the insurance. Since it is depositors who primarily benefit from the security this insurance provides, the government should take steps to ensure that depositors who want this security bear the cost of it and thus should make depositors pay the premiums for insuring their own accounts. 6. Which of the following is assumed by the argument?
(A) Banks are not insured by the government against default on the loans the banks make.
(B) Private insurance companies do not have the resources to provide banks or individual with deposit insurance.
(C) Banks do not always cover the cost of the deposit-insurance premiums by paying depositors lower interest rates on insured deposits than the banks would on uninsured deposits.
(D) The government limits the insurance protection it provides by insuring accounts up to a certain legally defined amount only.
(E) The government does not allow banks to offer some kinds of accounts in which deposits are not insured.
The National Association of Fire Fighters says that 45 percent of homes now have smoke detectors, whereas only 30 percent of homes had them 10 years ago. This makes early detection of house fires no more likely, however, because over half of the domestic smoke detectors are either without batteries or else inoperative for some other reason.
In order for the conclusion above to be properly drawn, which one of the following assumptions would have to be made?
(A) Fifteen percent of domestic smoke detectors were installed less than 10 years ago.
(B) The number of fires per year in homes with smoke detectors has increased.
(C) Not all of the smoke detectors in homes are battery operated.
(D) The proportion of domestic smoke detectors that are inoperative has increased in the past ten years.
(E) Unlike automatic water sprinklers, a properly functioning smoke detector cannot by itself increase fire safety in a home.
The workers at Bell Manufacturing will shortly go on strike unless the management increases their wages. As Bell's president is well aware, however, in order to increase the worker's wages, Bell would have to sell off some of its subsidiaries. So, some of Bell's subsidiaries will be sold.
The conclusion above is properly drawn if which one of the following is assumed?
(A) Bell Manufacturing will begin to suffer increased losses.
(B) Bell's management will refuse to increase its worker's wages.
(C) The workers at Bell Manufacturing will not be going on strike.
(D) Bell's president has the authority to offer the workers their desired wage increase.
(E) Bell's workers will not accept a package of improved benefits in place of their desired wage increase.
2. 我选择D. 因为监测器的增加未能提高预报率，只能解释为其效率降低，inoperative的比例上升。 B只有绝对数字的增加，而比例却可能降低，应该不对。 C，battery只是inoperative的一个方面，所以有否安装battery，与结论并无关系。事实上battery只是个陷阱，原文的含义就是over half of the domestic smoke detectors are inoperative 。
