A popular beach has long had a dolphin feeding program in which fish are given to dolphins several times a day; many dolphins get as much as half of their food each day there.  Although dolphins that first benefit from the program as adults are healthy and long-lived, their offspring have a lower life expectancy than offspring of dolphins that feed exclusively in the wild.
 
Which of the following, if true, most helps to explain the lower life expectancy of offspring of dolphins feeding at the beach compared to other young dolphins?

The prairie vole, a small North American grassland rodent, breeds year-round, and a group of voles living together consists primarily of an extended family, often including two or more litters.  Voles commonly live in large groups from late autumn through winter; from spring through early autumn, however, most voles live in far smaller groups.  The seasonal variation in group size can probably be explained by a seasonal variation in mortality among young voles.
 
Which of the following, if true, provides the strongest support for the explanation offered?

Which of the following most logically completes the argument?
 
United States manufacturers currently produce most of the world's solar-power generators--most of which are exported to Europe.  However, European manufacturers are emerging and probably will ultimately capture much of the European market.  The United States government is funding initiatives intended to encourage use of solar power within the United States.  If these initiatives succeed in increasing the demand for solar-power generators in the United States, United States manufacturers will probably maintain significant production levels, since __________.

A wildlife expert predicts that the reintroduction of the caribou into northern Minnesota would fail if the density of the timber wolf population in that region is more numerous than one wolf for every 39 square miles.
老师,请问B选项是怎么排除的?我理解是“密度超过每39平方英里就有一头狼”,B没有涉及任何形容词修饰density的问题。

[OG20]Critical Reasoning

Cognitive scientist: Using the pioneering work of comparative psychologist Gordon Gallup as a model, several studies have investigated animals’ capacity for mirror self-recognition (MSR). Most animals exposed to a mirror respond only with social behavior, such as aggression. However, in the case of the great apes, repeated exposure to mirrors leads to self-directed behaviors, such as exploring the inside of the mouth, suggesting that these animals recognize the reflection as an image of self. The implication of these studies is that the great apes have a capacity for self-awareness unique among nonhuman species.

The cognitive scientist makes which of the following assumptions in the argument above?

請問金老師,我有看到有人對B是用取非的方式做,但看完還是有些不理解,題目說其他動物沒有MSR,然後猩猩有MSR,所以作者推論他有自我認知。對B選項取非,就變成有動物沒有MSR,卻有自我認知,所以這樣就駁斥掉原文,請問這樣理解是否正確?另外可以請老師示範E選項的取非嗎?

Plant scientists have used genetic engineering on seeds to produce crop plants that are highly resistant to insect damage. Unfortunately, the seeds themselves are quite expensive, and the plants require more fertilizer and water to grow well than normal ones. Accordingly, for most farmers the savings on pesticides would not compensate for the higher seed costs and the cost of additional fertilizer. However, since consumer demand for grains, fruits, and vegetables grown without the use of pesticides continues to rise, the use of genetically engineered seeds of this kind is likely to become widespread.

In the argument given, the two portions in boldface play which of the following roles?

請問金老師,這題我選了A檢討後確實覺得C比較好,但我是看第二個黑底字判斷的,因為第二個後面有however,所以後面才是結論,但是第一個黑體字A說他是context是不是也可以?然後B的第二個黑體字麻煩可以解釋一下錯在哪嗎?

[OG19]Critical Reasoning

The heavy traffic in Masana is a growing drain on the city's economy—the clogging of the streets of the central business district alone cost the economy more than $1.2 billion over the past year. In order to address this problem, officials plan to introduce congestion pricing, by which drivers would pay to enter the city's most heavily trafficked areas during the busiest times of the day.

Which of the following, if true, would most strongly indicate that the plan will be a success?

想问下老师这个题C为啥是对的呢 我选了B 反思了一下 觉得B没有说方案实施之后的影响 但是C是不是也用了类比 难道不算主观判断吗?

[Undefined]Critical Reasoning

Veterinarians generally derive some of their income from selling several manufacturers' lines of pet-care products. Knowing that pet owners rarely throw away mail from their pet's veterinarian unread, one manufacturer of pet-care products offered free promotional materials on its products to veterinarians for mailing to their clients. Very few veterinarians accepted the offer, however, even though the manufacturer's products are of high quality.

Which of the following, if true, most helps to explain the veterinarians' reaction to the manufacturer's promotional scheme?
請問金老師,這題錯選了E,因為一開始讀完題目我覺得會拒絕的原因是獸醫不想讓顧客用別人的產品,而要用自己的產品,所以我看到E,他說獸醫會建議顧客用特製的產品(我想說特製不就是獸醫自己調配), 我覺得我的問題是不是把特製的產品和獸醫自家的產品混為一談。然後可以麻煩講一下C的思路
