标题: manhattan上几道逻辑题不是很明白求大神解答！
The Civil Service Act of 1883, also known as the Pendleton Act, which created a professional corps of administrators, was passed after a disappointed office-seeker assassinated President James A. Garfield. For a hundred years, this system anchored American government service to competence rather than corruption. The best way to preserve this state in the new millennium is to maintain the Pendleton Act as it is.
Which of the following would be most useful to evaluate the argument’s conclusion?
A  The methods that the Swiss and British governments have used to prevent corruption in government service for the past one hundred years
B The current level of job satisfaction among government office-seekers and office-holders
C The levels of competence and corruption in American government service between 1950 and the present
D  The number of Presidents assassinated since the passage of the Pendleton Act
E The percentage of office-holders fired or convicted on charges stemming from corruption during the first hundred years of the Pendleton Act

选C

According to a recent magazine article, of those office employees who typically work 8 hours at the office each day but sometimes say that they will work at home on a particular day, 25 percent actually work less than one hour. At the same time, over 90 percent of those same office employees believe they are more productive working at home than working in their office.
The statements above, if true, best support which of the following conclusions about the office employees discussed in the article?
Ａ On average, the office employees working at home for a day work fewer hours than office employees working at the office.
Ｂ10 percent of the office employees are less productive working from home than working in their office.
ＣAt least 15 percent of the office employees do not define productivity exclusively in terms of the number of hours worked.
ＤAt least 25 percent of the office employees can complete the same amount of work in one hour at home as in 8 hours at the office.
Ｅ  Some of the office employees make statements regarding their productivity that are not in fact true.
选C 不是很理解如果这25%的人在家工作少于在办公室工作1小时的话那不是代表他们是高效率的么可是现在90%的人又说他们高效怎么得出了15%呢

Recently in City X, residential developers have stopped buying land, contractors are going without work for longer periods, and specialty workers such as electricians are relying more on less lucrative, existing-home remodeling jobs. There must be fewer new residents moving to City X than there were previously.

Which of the following, if true, indicates a flaw in the reasoning above?

		This year several housing developments have gone on the market after being held up for months by legal red tape.
		The average size of a new home has increased significantly over the past several years.
		The population of City X is projected to grow by 4% this year, compared with only 3% for last year.
		The cost of materials such as lumber and cement has decreased over the past year.
		Sales of other big-ticket items, such as automobiles and boats, have remained steady over the past year.
