For the past 13 years, high school guidance counselors nationwide have implemented an aggressive program to convince high school students to select careers requiring college degrees. The government reported that the percentage of last year’s high school graduates who went on to college was 15 percent greater than the percentage of those who graduated 10 years ago and did so. The counselors concluded from this report that the program had been successful.
The guidance counselors’ reasoning depends on which one of the following assumptions about high school graduates?
(A) The number of graduates who went on to college remained constant each year during the 10-year period.
(B) Any college courses that the graduates take will improve their career prospects.
(C) Some of the graduates who went on to college never received guidance from a high school counselor.
(D) There has been a decrease in the number of graduates who go on to college without career plans.
(E) Many of last year’s graduates who went on to college did so in order to prepare for careers requiring college degrees.

6. Chronic fatigue syndrome is characterized by prolonged fatigue, muscular pain, and neurological problems. It is not know whether these symptoms are all caused by a single virus or whether each symptom is the result of a separate viral infection. A newly synthesized drug has been tested on those who suffer from chronic fatigue syndrome. Although the specific antiviral effects of this drug are unknown. It has lessened the severity of all of the symptoms of chronic fatigue syndrome. Thus there is evidence that chronic fatigue syndrome is, in fact, caused by one virus.
The argument assumes which one of following?
(A) All those who suffer from prolonged fatigue also suffer from neurological problems.
(B) It is more likely that the new drug counteracts one virus than that it counteracts several viruses.
(C) The symptoms of chronic fatigue syndrome are dissimilar to those of any other syndrome.
(D) Most syndromes that are characterized by related symptoms are each caused by a single viral infection.
(E) An antiviral medication that eliminates the most severe symptoms of chronic fatigue syndrome thereby cures chronic fatigue syndrome.
有是一个假设，我选的是C答案是B.
Household indebtedness, which some theorists regard as causing recession, was high preceding the recent recession, but so was the value of assets owned by households. Admittedly, if most of the assets were owned by quite affluent households, and most of the debt was owed by low-income households, high household debt levels could have been the cause of the recession despite high asset values: low-income households might have decreased spending in order to pay off debts while the quite affluent ones might simply have failed to increase spending. But, in fact, quite affluent people must have owed most of the household debt, since money is not lent to those without assets. Therefore, the real cause must lie elsewhere. 11. Which one of the following, if true, casts the most doubt on the argument?
(A) Prior to the recent recession, middle-income households owed enough debt that they had begun to decrease spending.
(B) The total value of the economy’s household debt is exceeded by the total value of assets held by households.
(C) Low-income households somewhat decreased their spending during the recent recession.
(D) During a recession the affluent usually borrow money only in order to purchase assets.
(E) Household debt is the category of debt least likely to affect the economy.
