were more than twice as likely to participate in adult educa-tion than those
whose highest educational attainment was a high school diploma or GED (high

【正确答案】
E
【答案解析】Each of the given statements is true except Choice E.
(A) In 199l, more than 50% of the adults whose highest degree was at least a bachelor's degree participated in adult education, whereas among those whose highest educational attain-ment was a high school diploma or GED (high school equivalency diploma) fewer than 25% participated.
(B) From I991 to 1995, among those adults whose highest educational attainment was grades 9-12, without earning a high school diploma, the rate of participation in adult edu-cation increased from about 15% to 23%, an increase of about 50%. None of the other groups had nearly that great an increase.
(C) Since the population of the country grew between 1991 and 1995, and the rate of par-ticipation in adult education programs increased in every category, the total number of people participating had to increase.
(D) From 1991 to 1995 the rate of participa-tion in adult education for those who had attained at least a bachelor's degree increased from about 52% to 58%, the least increase of any group on both an absolute and percent basis.
(E) Without knowing how many adults have earned a college degree and how many have attended'some college without earning a col-lege degree, it is impossible to make this ,con-clusion. For example, 50% of 100,000,000 is much more than 58% of 50,000,000.
单选题
If in the United States in 1995, there were 50 mil-lion employed adults and 20 million adults not in the the labor force, then approximately what was the ratio of the number of employed adults participating in adult education to the number of people not in the labor force participating in adult education?
A. 5:4B. 5:2C. 10:3 D. 5:1 E. 6:l
【正确答案】
E
【答案解析】50% of 50,000,000 = 25,000,000; 20% of 20,000,000 = 4,000,000.
25,000,000:4,000,000 = 25:4 = 6.25:1.
单选题
Bob and Jack share an apartment. If each month Bob pays a dollars and Jack pays b dollars, what percent of the total cost does Bob pay?
【正确答案】
E
【答案解析】The total rent is a + b, so Bob's fractional share is [*]. To convert to a percent, simply multiply by 100%: [*]
**Use TACTIC 2, Chapter 11. Pick two easy-to-use numbers. If Bob pays $1 and Jack pays $2, then Bob pays [*] of the rent. Only [*] is equal to [*] when a = and b = 2.
