GWD-27-Q2: Electronic computer chips made of tiny silicon wafers now regularly contain millions of electronic switches. Unfortunately, electronic switches that are this small cannot withstand intense radiation. Micro-Mechanics plans to produce a chip that, because it uses only microscopic mechanical switches, will be invulnerable to radiation damage. The switches will, however, be slower than electronic switches and the chip will contain only 12,000 switches. For there to be a market for Micro-Mechanics’ chip as a result of the apparent advantage described above, each of the following would have to be true EXCEPT:
- There will be applications in which the speed attainable by an electronic switch is not essential.
- Switches
used on electronic chips that contain only 12,000 switches are more vulnerable to radiation damage than the switches on Micro-Mechanics’ chip will be. - There will be applications for computer chips in environments where the chips may have to survive intense radiation.
- Some
devices in which computer chips will be used will have other components that will be able to function during or after exposure to radiation. - Manufacturers
are able to protect electronic computer chips against exposure to intense radiation, where this protection is necessary.
Ans:E The conclusion of the argument is in the question stem "For there to be a market for Micro-Mechanics’ chip as a result of the apparent advantage described above"
This answer asked "which of the following is the necessary assumption EXCEPT" The assumption is "Consumers will buy Micro-Mechanics’ chip" - answers: A, B, C, D
GWD-29-Q16 Political Advertisement: Mayor Delmont’s critics complain about the jobs that were lost in the city under Delmont’s leadership. Yet the fact is that not only were more jobs created than were eliminated, but each year since Delmont took office the average pay for the new jobs created has been higher than that year’s average pay for jobs citywide. So it stands to reason that throughout Delmont’s tenure the average paycheck in this city has been getting steadily bigger.
Which of the following, if true, most seriously weakens the argument in the advertisement?
- The unemployment rate in the city is higher today than it was when Mayor Delmont took office.
- The average pay for jobs in the city was at a ten-year low when Mayor Delmont took office.
- Each
year during Mayor Delmont’s tenure, the average pay for jobs that were eliminated has been higher than the average pay for jobs citywide. - Most of the jobs eliminated during Mayor Delmont’s tenure were in declining industries.
- The average pay for jobs in the city is currently lower than it is for jobs in the suburbs surrounding the city
请教各位大大们,这题B选项如何排除以及Ans:C选项如何看出????? Because B is irrelevant. You have to read the conclusion carefully - So it stands to reason that throughout Delmont’s tenure the average paycheck in this city has been getting steadily bigger. (C) points out a possibility that the average pay for jobs lost has been higher than the average pay for jobs created.
GWD27-Q35:
In polluted environments, dolphins gradually accumulated toxins in their body fat, and the larger the dolphin, the more accumulated toxin it can tolerate. Nearly 80 percent of the toxins a female dolphin has accumulated pass into the fat-rich milk her nursing calf ingests. Therefore, the unusually high mortality rate among dolphin calves in the industrially contaminated waters along Florida’s Gulf Coast is probably the result of their being poisoned by their mother’s milk. Which of the following, if true, most strengthens the argument?
- The survival rate of firstborn dolphin calves in the area along Florida’s Gulf
Coast is highest for those whose mothers were killed before they were weaned. - The rate at which adult dolphins living in the waters along Florida’s Gulf
Coast accumulate toxins is no higher than that of adult dolphins in comparably polluted waters elsewhere. - Among dolphin calves born in the area along Florida’s Gulf
Coast, the mortality rate is highest among those with living siblings. - As dolphins age, they accumulate toxins from the environment more slowly than when they were young.
- Dolphins, like other marine mammals, have a higher proportion of body fat than do most land mammals.
Ans:A
请教各位大大们,这题A选项问一个非常弱智的问题 虽然A确实导出奶与致死率有关, 但我想请问一下A表示母dolphin在断奶前死掉它孩子存活率高?? 若这母dolphin在断奶前死掉它孩子怎么生出来? Give birth first -> breast feeding ->wean Just read carefully The survival rate of firstborn dolphin calves in the area along Florida’s Gulf Coast is highest for those (calves) whose mothers were killed before they (calves) were weaned. If 母dolphin 在它孩子断奶前 死掉, 它孩子存活率高.
