标题: OG 16, CR 35题，Evaluate题型，求助 [打印本页] 作者: sarroul 时间: 2016-8-10 19:55 标题: OG 16, CR 35题，Evaluate题型，求助 35. The growing popularity of computer-based activities was widely expected to result
in a decline in television viewing, since it had been assumed that people lack
sufficient free time to maintain current televisionviewing levels while spending
increasing amounts of free time on the computer. That assumption, however, is
evidently false: In a recent mail survey concerning media use, a very large majority
of respondents who report increasing time spent per week using computers report
no change in time spent watching television.
Which of the following would it be most useful to determine in order to evaluate
the argument?
(A) Whether a large majority of the survey respondents reported watching
television regularly
(B) Whether the amount of time spent watching television is declining
among people who report that they rarely or never use computers
(C) Whether the type of television programs a person watches tends to
change as the amount of time spent per week using computers increases
(D) Whether a large majority of the computer owners in the survey reported
spending increasing amounts of time per week using computers
(E) Whether the survey respondents’ reports of time spent using computers
included time spent using computers at work
正确答案是E。
不知道大家一般做Evaluate是什么思路？ 这道题我貌似连中心都没明白。OG的解释是，Key is about free time, and the arguement is trying to debunk the assumption.
求助坛子里的小伙伴！！

it had been assumed that people lack sufficient free time to maintain current television viewing levels while spending increasing amounts of free time on the computer-->假設自由支配時間是固定的，所以電腦時間增加就會壓縮看電視時間
42. Trancorp currently transports all its goods to Burland Island by truck. The only bridge over the channel separating Burland from the mainland is congested, and trucks typically spend hours in traffic. Trains can reach the channel more quickly than trucks, and freight cars can be transported to Burland by barges that typically cross the channel in an hour. Therefore, to reduce shipping time, Trancorp plans to switch to trains and barges to transport goods to Burland.
題目focus在time reduce，這個方法有沒有省到時間？—> 推測：其他方式沒有更花時間
Which of the following would be most important to know in determining whether Trancorp’s plan, if implemented, is likely to achieve its goal?
(A) Whether transportation by train and barge would be substantially less expensive than transportation by truck 主題無關
(B) Whether there are boats that can make the trip between the mainland and Burland faster than barges can 跟現在的方法無關，無法知道這個方法到底有沒有節省時間
(C) Whether loading the freight cars onto barges is very time consuming 符合推測
(D) Whether the average number of vehicles traveling over the bridge into Burland has been relatively constant in recent years 主題無關
(E) Whether most trucks transporting goods into Burland return to the mainland empty主題無關
56. Certain genetically modified strains of maize produce a powerful natural insecticide. The insecticide occurs throughout the plant, including its pollen. Maize pollen is
dispersed by the wind and frequently blows onto milkweed plants that grow near maize fields. Caterpillars of monarch butterflies feed exclusively on milkweed leaves. When these caterpillars are fed milkweed leaves dusted with pollen from modified maize plants, they die. Therefore, by using genetically modified maize, farmers put monarch butterflies at risk.
using genetically modified maize—>farmers put monarch butterflies at risk.
預測：是否有時間差？有無他因？
Which of the following would it be most useful to determine in order to evaluate the argument?
(A) Whether the natural insecticide is as effective against maize-eating insects as commercial insecticides typically used on maize are 主題無關
(B) Whether the pollen of genetically modified maize contains as much insecticide as other parts of these plants 無關比較
(C) Whether monarch butterfly caterpillars are actively feeding during the part of the growing season when maize is releasing pollen 有時間差
(D) Whether insects that feed on genetically modified maize plants are likely to be killed by insecticide from the plant’s pollen 主角無關
(E) Whether any maize-eating insects compete with monarch caterpillars for the leaves of milkweed plants growing near maize fields 主題無關，無法評估對monarch有沒有risk
86. Scientists have modified feed corn genetically, increasing its resistance to insect pests. Farmers who tried out the genetically modified corn last season applied less insecticide to their corn fields and still got yields comparable to those they would have gotten with ordinary corn. Ordinary corn seed, however, costs less, and what these farmers saved on insecticide rarely exceeded their extra costs for seed.改用新種子省下的殺蟲劑，無法彌補新種子的成本 Therefore, for most feedcorn farmers, switching to genetically modified seed would be unlikely to increase profits.
看到profit—>要注意成本（人力/種子成本/農藥灌溉成本...等）及收入問題
Which of the following would it be most useful to know in order to evaluate the argument?
(A) Whether there are insect pests that sometimes reduce feed-corn yields, but against which commonly used insecticides and the genetic modification are equally ineffective 違背前提，已經說新舊的產量差不多
(B) Whether the price that farmers receive for feed corn has remained steady over the past few years out of scope，沒有說到新舊作物的銷售價格
(C) Whether the insecticides typically used on feed corn tend to be more expensive than insecticides typically used on other crops. —>out of scope
(D) Whether most of the farmers who tried the genetically modified corn last season applied more insecticide than was actually necessary 是否ㄧ開始就花過多的不必要成本導致無法cover買新種子的成本
(E) Whether, for most farmers who plant feed corn, it is their most profitable crop 無關
92. Normally, the pineal gland governs a person’s sleepwake cycle by secreting melatonin in response to the daily cycle of light and darkness as detected by the eye. Nonetheless, many
people who are totally blind due to lesions in the visual cortex of the brain easily maintain a 24- hour sleep-wake cycle. So the neural pathway by which the pineal gland receives information from the eye probably does not pass through the visual cortex.
For purposes of evaluating the argument it would be most useful to establish which of the following?
(A) Whether melatonin supplements help people who have difficulty maintaining a 24-hour sleep cycle to establish such a pattern 沒有提到那些瞎子是否有melatonin supplements—>擴大範圍
(B) Whether the melatonin levels of most totally blind people who successfully maintain a 24-hour sleep-wake cycle change in response to changes in exposure to light and darkness 符合預期方向
(C) Whether melatonin is the only substance secreted by the pineal gland 重點在於沒有vc處理—>無關
(D) Whether most people who do not have a 24-hour sleep-wake cycle nevertheless have a cycle of consistent duration 無關
(E) Whether there are any people with normal vision whose melatonin levels respond abnormally to periods of light and darkness 無關，重點在vc
