9. Advertisement: Clark brand-name parts are made for cars manufactured in this country. They satisfy al of our government automotive test-the toughest such tests in the world. With foreign-made parts, you never know which might be reliable and which are cheap look-alikes that are poorly constructed and liable to cost you hundreds of dollars in repairs. Therefore, be smart and insist on brand-name parts by Clark for your car.
The argument requires the assumption that
(A) Clark parts are available only in this country
(B) foreign-made parts are not suitable for cars manufactured in this country
(C) no foreign-made parts satisfy our government standards
(D) parts that satisfy our government standards are not as poorly constructed as cheap foreign-made parts
(E) if parts are made for cars manufactured in our country, they are not poorly constructed
答案,我觉得这个是bridge型的假设题,但是C为什么不行呢?也是个bridge啊? 8. Measurements of the extent of amino-acid decomposition in fragments of eggshell found at archaeological sites in such places as southern Africa can be used to obtain accurate dates for sites up to 200,000 years old. Because the decomposition is slower in cool climates, the technique can be used to obtain accurate dates for sites almost a million years old in cooler regions.
The information above provides the most support for which one of the following conclusions?
(A) The oldest archaeological sites are not in southern Africa, but rather in cooler regions of the world.
(B) The amino-acid decomposition that enables eggshells to be used in dating does not take place in other organic matter found at ancient archaeological sites.
(C) If the site being dated had been subject to large unsuspected climatic fluctuations during the time the eggshell has been at the site, application of the technique is less likely to yield accurate results.
(D) After 200,000 ears in a cool climate, less than one-fifth of the amino acids in a fragment of eggshell that would provide material for dating with the technique will have decomposed and will thus no longer be suitable for examination by the technique.
(E) Fragments of eggshell are more likely to be found at ancient archaeological sites in warm regions of the world than at such sites in cooler regions.
