Paradox

NO.1

1.Industry experts expect improvements in job safety training to lead to safer work environments. A recent survey indicated, however, that for manufacturers who improved job safety training during the 1980s, the number of on-the-job accidents tended to increase in the months immediately following the changes in the training programs.

Which one of the following, if true, most helps to resolve the apparent discrepancy in the passage above?

A.A similar survey found that the number of onthe-job accidents remained constant after job safety training in the transportation sectorwas improved.
B.Manufacturers tend to improve their job safety training only when they are increasing the size of their workforce.
C. Manufacturers tend to improve job safetytraining only after they have noticed that the number of on-the-job accidents has increased.
D. It is likely that the increase in the number ofon-the-job accidents experienced by many companies was not merely a random fluctuation.
E.Significant safety measures, such as protective  equipment and government safetyinspections, were in place well before the improvements in job safety training.

NO.2
2. Cigarette companies claim that manufacturing both low- and high-nicotine cigarettes allows smokers to choose how much nicotine they want. However, a recent study has shown that the levels of nicotine found in the blood of smokers who smoke one pact of cigarettes per day are identical at the end of a day's worth of smoking, whatever the level of nicotine in the cigarettes they smoke.

Which one of the following, if true, most helps to explain the finding of nicotine study?

A. Blood cannot absorb more nicotine per day than that found in the smoke from a package of the lowest-nicotine cigarettes available.
B. Smokers of the lowest-nicotine cigarettes available generally smoke more cigarettes per day than smokers of high-nicotine cigarettes.
C. Most nicotine is absorded into the blood of a smoker even if it is delivered in smaller quatities.
D. The level of tar in cigarettes is higher in low-nicotine cigarettes than it is in some high-nicotine cigarettes.
E. When taking in nicotine by smoking cigarettes is discontinued, the level of nicotine in the blood decreases steadily.
NO.3

3.Raisins are made by drying grapes in the sun. Although some of the sugar in the grapes is caramelized in the process, nothing is added. Moreover, the only thing removed from the grapes is the water that evaporates during the drying, and water contains no calories or nutrients. The fact that raisins contain more iron per calorie than grapes do is thus puzzling.

which one of the following, if true, most helps to explain why raisins contain more iron per calorie than do grapes?

A. Since grapes are bigger than raisins, it takes several bunches of grapes to provide the same amount of iron as a handful of raisins does.
B. Caramelized sugar cannot be digested, so its calories do not count toward the calorie content of raisins.
C. The body can absorb iron and other nutrients more quickly from grapes than from raisins because of the relatively high water content of grapes.
D. Raisins, but not grapes, are available year- round, so many people get a greater share of their yearly iron intake from raisins than from grapes.
E. Raisins are often eaten in combination with other iron-containing foods, while grapes are usually eaten by themselves.
NO.4

4. Vervet monkeys use different alarm calls to warn each other of nearbypredators, depending on whether the danger comes from land or from the air.

Which one of the following, if true, contributes most to an explanation of the behavior of vervet monkeys described above?

A. By varying the pitch of its alarm call, a vervet monkey can indicate the number of predators approaching.
B. Different land-based predators are responsible for different numbers of vervet monkey deaths.
C. No predators that pose a danger to vervet monkeys can attack both from land and from the air.
D. Vervet monkeys avoid land-based predators by climbing trees but avoid predation from the air by diving into foliage.
E. Certain land-based predators feed only on vervet monkeys, whereas every predator that attacks vervet monkeys from the air feeds on many different animals.
NO.5 AA

The following appeared in the editorial section of a local newspaper.

“In the first four years that Montoya has served as mayor of the city of San Perdito, the population has decreased and the unemployment rate has increased. Two businesses have closed for each new business that has opened. Under Varro, who served as mayor for four years before Montoya, the unemployment rate decreased and the population increased. Clearly, the residents of San Perdito would be best served if they voted Montoya out of office and reelected Varro.”

果然还是要理解句意...第二题的paradox一开始没看懂：应该是不管是低尼古丁含量的香烟还是高尼古丁含量的 最后吸一包烟的他们血液中的尼古丁含量是相同的
然后OA的意思是血液每天吸收的尼古丁不能比从一包最低尼古丁香烟中吸收更多的尼古丁

BG: Experts say that training contributes to reduce the by-working accidents.
However: After a training program the accident rates increased
Resolve:  There are other factors contribute to accident rate that year
没选对B，overall number of workers increased 自我检讨：读题不仔细，increase的不是rate是number，不然得不出正确答案了。

Cigarette manufacturer says they produce cigarette both of high nicotin and low nicotin for smokers to choose from.
But research shows that there is no difference in nicotin in body between people who smoke high nicotin and people who smoke low nicotin a pack cigarette per day.,
Resolve: Samples are not representative...好怂的答案
A 看到第一个觉得好有道理就选了。。清早起来shower之后还是走神是肿么回事。。。

3. 40s
Raisins are dried from grapes in the sun. Sugar are caramelized and only thing gone is water exvaporated.
But raisin is contains more iron per calorie than grape.
Resolve: Problem might be in the caramelized sugar??
B Bingo! However it's not that caramelized sugar generates more iron, but that caramelized suger cannot be counted in the overall calorie : Denominator is larger, numerator remains constant, then the rate becomes larger.


4.  20s
V monkeys use different alarm calls to warn their nearby monkeys to illustrate different predators from air or from land.

Resolve: They have to react different to predators from air and from land to survive.
D Yoooo!
