7. The incidence in Japan of most types of cancer is remarkable low compared to with in North America,especially considering that Japan has a modern life-style, industrial pollution included. The cancer rates,however, for Japanese people who immigrate to North America and adopt the diet of North Americans approximate the higher cancer rates prevalent in North America.
If the statements above are true, they provide the most support for which one of the following?
(A) The greater the level of industrial pollution in a country, the higher that country’s cancer rate will tend to be.
(B) The stress of life in North America is greater than that of life in Japan and predisposes to cancer.
(C) The staple foods of the Japanese diet contain elements that cure cancer.
(D) The relatively low rate of cancer among people in Japan does not result from a high frequency of a protective genetic trait among Japanese people.
(E) The higher cancer rates of Japanese immigrants to North America are caused by fats in the North American diet.

13. This summer, Jennifer, who has worked at KVZ Manufacturing for just over three years, plans to spend with her family the entire four weeks of paid vacation to which she is entitled this year. Anyone who has worked at KVZ Manufacturing for between one and four years is automatically entitled to exactly three weeks paid vacation each year but can apply up to half of any vacation time that remains unused at the end of one year to the next year’s vacation.
If the statements above are all true, which one of the following must also be true on the basis of them?
(A) Jennifer did not use two weeks of the paid vacation time to which she was entitled past year.
(B) If Jennifer continues to work for KVZ Manufacturing, she will only be entitled to three weeks paid vacation next year.
(C) The majority of KVZ’s employees use each year all of the paid vacation time to which they are entitled.
(D) Last year Jennifer took only one week of the paid vacation time to which she was entitled.
(E) KVZ Manufacturing sometimes allows extra vacation time to employees who need to spend more time with their families.
answer :A my choice
24. It now seems clear that the significant role initially predicted for personal computers in the classroom has not become fact. One need only look to the dramatic decline in sales of computers for classroom use in the past year for proof that the fad has passed.
Which one of the following arguments contains flawed reasoning parallel to that in the argument above?
(A) Clearly government legislation mandating the reduction of automobile emissions has been at least partially successful, as is demonstrated by the fact that the air of the 20 largest cities now contains smaller amounts of the major pollutants mentioned in the legislation than it did before the legislation was passed.
(B) Mechanical translation from one language into another, not merely in narrow contexts such as airline reservations but generally, is clearly an idea whose time has come. Since experts have be4en working on the problem for 40 years, it is now time for the accumulated expertise to achieve a breakthrough.
(C) Sales of computers for home use will never reach the levels optimistically projected by manufacturers.The reason is that home use was envisioned as encompassing tasks, such as menu planning and checkbook reconciliation, that most homemakers perform in much simpler ways than using a computer would require.
(D) It is apparent that consumers have tired of microwave ovens as quickly as they initially came to accept this recent invention. In contrast to several years of increasing sales following the introduction of microwave ovens, sales of microwave ovens flattened last year indicating that consumers have found relatively little use for these devices.
(E) Creating incentives for a particular kind of investment inevitably engenders boom-and-bust cycles. The evidence is in the recent decline in the value of commercial real estate, which shows that, although the government can encourage people to put up buildings, it cannot guarantee that those buildings will be fully rented or sold.
