Unlike the wholesale price of raw wool, the wholesale price of raw cotton has fallen considerably in the last year. Thus, although the retail price of cotton clothing at retail clothing stores has not yet fallen, it will inevitably fall. Which of the following, if true, most seriously weakens the argument above? (A) The cost of processing raw cotton for cloth has increased during the last year. (B) The wholesale price of raw wool is typically higher than that of the same volume of raw cotton. © The operating costs of the average retail clothing store have remained constant during the last year. (D) Changes in retail prices always lag behind changes in wholesale prices. (E) The cost of harvesting raw cotton has increased in the last year. OA: Please explain the question and your answer choices too.

John and Ed work for the same Sales Company. John receives a $600 basic salary plus 20 percent of any profit he realizes for the company in excess of $5,000, while Ed receives an $800 basic salary in addition to 40 percent of any profit he realizes for the company only if the total profit he realizes is greater than $8,000, otherwise he receives a flat salary of $1,000. For what amount of profit will both John and Ed earn the same amount? (A)$1,000 (B)$1,200 ©$2,400 (D)$6,000 (E)$7,000 Sorry, don't have the OA to this .... Please show how to solve this problem.

A certain mayor has proposed a fee of five dollars per day on private vehicles entering the city, claiming that the fee will alleviate the city’s traffic congestion. The mayor reasons that, since the fee will exceed the cost of round-trip bus fare from many nearby points, many people will switch from using their cars to using the bus. Which of the following statements, if true, provides the best evidence that the mayor’s reasoning is flawed? (A) Projected increases in the price of gasoline will increase the cost of taking a private vehicle into the city. (B) The cost of parking fees already makes it considerably more expensive for most people to take a private vehicle into the city than to take a bus. © Most of the people currently riding the bus do not own private vehicles. (D) Many commuters opposing the mayor’s plan have indicated that they would rather endure traffic congestion than pay a five-dollar-per day fee. (E) During the average workday, private vehicles owned and operated by people living within the city account for twenty percent of the city’s traffic congestion. OA: Please explain your answer choice and why the other options are incorrect. Thanks

Some people have questioned the judge’s objectivity in cases of sex discrimination against women. But the record shows that in sixty percent of such cases, the judge has decided in favor of the women. This record demonstrates that the judge has not discriminated against women in cases of sex discrimination against women. The argument above is flawed in that it ignores the possibility that A. a large number of the judge’s cases arose out of allegations of sex discrimination against women B. many judges find it difficult to be objective in cases of sex discrimination against women C. the judge is biased against women defendants or plaintiffs in cases that do not involve sex discrimination D. the majority of the cases of sex discrimination against women that have reached the judge’s court have been appealed from a lower court E. the evidence shows that the women should have won in more than sixty percent of the judge’s cases involving sex discrimination against women OA:

A recent spate of launching and operating mishaps with television satellites led to a corresponding surge in claims against companies underwriting satellite insurance. As a result, insurance premiums shot up, making satellites more expensive to launch and operate. This, in turn, has added to the pressure to squeeze more performance out of currently operating satellites. Which of the following, if true, taken together with the information above, best supports the conclusion that the cost of television satellites will continue to increase? A. Since the risk to insurers of satellites is spread over relatively few units, insurance premiums are necessarily very high. B. When satellites reach orbit and then fail, the causes of failure are generally impossible to pinpoint with confidence. C. The greater the performance demands placed on satellites, the more frequently those satellites break down. D. Most satellites are produced in such small numbers that no economies of scale can be realized. E. Since many satellites are built by unwieldy international consortia, inefficiencies are inevitable OA:

IS the standard deviation of a set less than 25000 a) range of set is 15000 b) median is 120000 Sorry, don't have the OA to this one. IMO, it shoule be E since we do not know the elements in the set. Range and Median is not sufficient to determine the SD.

Guess, you are right .... thanks for the clarification ...
