On Pacific islands, a newly arrived gecko species, the house gecko, is displacing the previously established mourning gecko in urban areas, but populations of the two species are more stable in rural areas far from human settlement. The house gecko does not attack the mourning gecko, but in areas where insects congregate it prevents the mourning gecko from feeding on them.
Which of the following contributes most to an explanation of the difference between gecko populations in urban and rural areas?
(A) In urban areas, geckos are valued because they eat so many insects. (B) Geckos defend territories against other members of the same species. (C) House geckos that arrive on islands are carried there in boats and planes. (D) In places where there are lighted buildings, insects tend to gather around the light. (E) Mourning geckos are all females and reproduce asexually, but house geckos reproduce sexually.

Northern Air has dozens of flights daily into and out of Belleville Airport, which is highly congested. Northern Air depends for its success on economy and quick turnaround and consequently is planning to replace its large planes with Skybuses, whose novel aerodynamic design is extremely fuel efficient. The Skybus' fuel efficiency results in both lower fuel costs and reduced time spent refueling.
Which of the following, if true, could present the most serious disadvantage for Northern Air in replacing their large planes with Skybuses?
(A) The Skybus would enable Northern Air to schedule direct flights to destinations that currently require stops for refueling. (B) Aviation fuel is projected to decline in price over the next several years. (C) The fuel efficiency of the Skybus would enable Northern Air to eliminate refueling at some of its destinations, but several mechanics would lose their jobs. (D) None of Northern Air's competitors that use Belleville Airport are considering buying Skybuses. (E) The aerodynamic design of the Skybus causes turbulence behind it when taking off that forces other planes on the runway to delay their takeoffs.

Which of the following most logically completes the argument?
A new machine for harvesting corn will allow rows to be planted only fifteen inches apart, instead of the usual thirty inches. Corn planted this closely will produce lower yields per plant. Nevertheless, the new machine will allow corn growers to double their profits per acre because __________.
(A) with the closer spacing of the rows, the growing corn plants will quickly form a dense canopy of leaves, which will, by shading the ground, minimize the need for costly weed control and irrigation (B) with the closer spacing of the rows, corn plants will be forced to grow taller because of increased competition for sunlight from neighboring corn plants (C) with the larger number of plants growing per acre, more fertilizer will be required (D) with the spacing between rows cut by half, the number of plants grown per acre will almost double (E) with the closer spacing of the rows, the acreage on which corn is planted will be utilized much more intensively than it was before, requiring more frequent fallow years in which corn fields are left unplanted作者: balapupu 时间: 2011-12-7 21:36
Question #6. Weaken-CE. December 2000 LSAT, Section 2, #7. The correct answer choice is (A) The heart of the argument is a causal claim that the reason today’s newspapers are full of stories about violent crime is that violent crime has now risen to a point where it is out of control. MVC = more violent crimes NFS = more news stories about violent crimes C E MVC NFS On the basis of this relationship, the author adds for good measure that one should not leave one’s home! From a form standpoint, this problem is very similar to #3 in this problem set. This is one of the keys to the LSAT—you must recognize the patterns that exist within the test and then capitalize on them when they appear. All the problems in the set include causality. From this point on, you must recognize causality when it appears and then properly respond to it. Your ability to recognize these forms will give you an advantage in both speed and confidence, and ultimately raise your score. Answer choice (A): This is the correct answer. This answer presents an alternate cause to the scenario presented above, namely that more comprehensive coverage leads to more news stories, not more violent Answer choice (B): This Opposite answer strengthens the argument. Answer choice (C): This answer strengthens the argument, if anything. Answer choice (D): This is an answer that many people select. The answer is incorrect because it fails to account for other violent crimes beside murder. Indicating that murder comprised a higher percentage of violent crimes in the old days than today does not address the total number of crimes being committed. Since the argument concludes that “violent crime is now out of control,” this answer is incorrect. Consider the following example: Old Days Today Total number of murders 3 1,000 Total number of violent crimes 4 50,000 Percentage of violent crimes that are murders 75% 2% In this example, although murder was a higher proportion of the violent crimes in the old days, today there are many more violent crimes. This shows that the scenario in the answer choice does not have to undermine the argument. In the chapter on Numbers and Percentages we will revisit the concept of proportion versus total numbers and discuss how the test makers use numerical ideas to attack test takers. Answer choice (E): The role played by magazines in informing the public does not address why there are so many stories about violent crime or if violent crime is now out of control.

Unlike newspapers in the old days, today’s newspapers and televised news programs are full of stories about murders and assaults in our city. One can only conclude from this change that violent crime is now out of control, and, to be safe from personal attack, one should not leave one’s home except for absolute necessities.
The logic chain of the argument is that since more stories about murders and assaults have been reported by newspapers and televised news programs, people should think that violent crime is now out of control and should stay at home avoiding personal attack. Which one of the following, if true, would cast the most serious doubt on the conclusion?
(A) Newspapers and televised news programs have more comprehensive coverage of violent crime than newspapers did in the old days.
In this case, it is reasonable to find out more violent crimes today than those in old days, but the real threat of violent crimes may not increase. BA (B) National data show that violent crime is out of control everywhere, not just in the author’s city.
Actually, this answer choice strengthens the argument, rather than casts doubt on the conclusion. (C) Police records show that people experience more violent crimes in their own neighborhoods than they do outside their neighborhoods.
It feels like a Shell Game answer. It seems like the safety in neighborhoods is lower than that is outside neighborhoods. However, the comparison does not weaken the conclusion that people should not leave their homes. For example, if a person leaves his home, there is more likely that a theft would happen in his home; on the other hand, if he stays at home, the probability may be reduced.
Besides, this answer strengthens the argument. (D) Murder comprised a larger proportion of violent crimes in the old days than it does today.
Even though the percentage may decrease, the total number of crimes may increase today. (E) News magazines play a more important role today in informing the public about crime than they did in the old days.
Actually, this answer choice strengthens the argument.
1. (24021-!-item-!-188;#058&000691) On Pacific islands, a newly arrived gecko species, the house gecko, is displacing the previously established mourning gecko in urban areas, but populations of the two species are more stable in rural areas far from human settlement. The house gecko does not attack the mourning gecko, but in areas where insects congregate it prevents the mourning gecko from feeding on them. Which of the following contributes most to an explanation of the difference between gecko populations in urban and rural areas? (A) In urban areas, geckos are valued because they eat so many insects.
This answer choice does not point out the difference between house gecko and mourning gecko. (B) Geckos defend territories against other members of the same species.
The same to A. (C) House geckos that arrive on islands are carried there in boats and planes.
The way how house geckos came to islands is outside the scope of the argument. (D) In places where there are lighted buildings, insects tend to gather around the light.
It seems irrelevant, but a more thorough analysis reveals that it is the best answer. As we know, there are more lighted buildings in urban areas than in rural areas. So it is reasonable to assume that there are more insects congregating in urban areas than in rural areas. What’s more, the argument points out that in areas where insects congregate house gecko prevents mourning gecko from feeding on them. Thus, the logic chain is reasonable. BA (E) Mourning geckos are all females and reproduce asexually, but house geckos reproduce sexually. The same to A.
2. (24069-!-item-!-188;#058&000703) Downtown Villieu was once a flourishing business district, but most Villieu-area businesses are now located only in the suburbs. The office buildings downtown lack the modern amenities most business operators demand today. To lure more businesses downtown, Villieu officials plan to have several modern office buildings constructed and to offer reduced local tax rates to any business that leases space in a new downtown building. Which of the following, if true, most threatens the plan's likelihood of success? (A) Most of the businesses currently located in downtown Villieu have long-term leases on the space they occupy there.
It seems to weaken the argument, but if the local tax rates in new buildings are lower than those of their currently located buildings, they may choose the new buildings. So it cannot weaken the argument. (B) The existing office buildings in downtown Villieu have, on average, a much higher vacancy rate than do office buildings in Villieu's suburbs.
The same to A. (C) The local tax rates in Villieu's suburbs are significantly lower than downtown Villieu's proposed rate for businesses that lease space in the new office buildings.
In this case, it is reasonable to predict that the plan would not succeed, considering the higher cost to move in new buildings. BA (D) Most of the businesses that currently lease office space in downtown Villieu also lease office space in Villieu's suburbs.
This answer is irrelevant. (E) With the new office buildings, downtown Villieu would have a greater amount of modern office space than any other downtown business district in the region.
Actually, this answer choice strengthens the argument.
3. (24117-!-item-!-188;#058&000708) Northern Air has dozens of flights daily into and out of Belleville Airport, which is highly congested. Northern Air depends for its success on economy and quick turnaround and consequently is planning to replace its large planes with Skybuses, whose novel aerodynamic design is extremely fuel efficient. The Skybus' fuel efficiency results in both lower fuel costs and reduced time spent refueling. Which of the following, if true, could present the most serious disadvantage for Northern Air in replacing their large planes with Skybuses? (A) The Skybus would enable Northern Air to schedule direct flights to destinations that currently require stops for refueling.
In fact, this answer choice strengthens the plan. (B) Aviation fuel is projected to decline in price over the next several years.
It is irrelevant. (C) The fuel efficiency of the Skybus would enable Northern Air to eliminate refueling at some of its destinations, but several mechanics would lose their jobs.
Unemployment is outside the scope of the argument. (D) None of Northern Air's competitors that use Belleville Airport are considering buying Skybuses.
Perhaps, they cannot afford the Skybuses, not meaning that this kind of airplane is not good. (E) The aerodynamic design of the Skybus causes turbulence behind it when taking off that forces other planes on the runway to delay their takeoffs. In this case, the Skybus would increase delays, thus weakening the advantage of Northern Air, which depends for its success on economy and quick turnaround. BA
4. (24257-!-item-!-188;#058&001200) Which of the following most logically completes the argument? A new machine for harvesting corn will allow rows to be planted only fifteen inches apart, instead of the usual thirty inches. Corn planted this closely will produce lower yields per plant. Nevertheless, the new machine will allow corn growers to double their profits per acre because __________. (A) with the closer spacing of the rows, the growing corn plants will quickly form a dense canopy of leaves, which will, by shading the ground, minimize the need for costly weed control and irrigation
In this case, it points out an advantage that closer planting has. Since the need for costly weed control and irrigation is minimized, the profits will increase. BA (B) with the closer spacing of the rows, corn plants will be forced to grow taller because of increased competition for sunlight from neighboring corn plants
Actually, this weakens the argument. Growing taller will lower yields per plant. (C) with the larger number of plants growing per acre, more fertilizer will be required
This is similar to B. (D) with the spacing between rows cut by half, the number of plants grown per acre will almost double
Even though the number of plants doubles, the profits won’t make sure to increase per acre, considering the lower yields per plant. (E) with the closer spacing of the rows, the acreage on which corn is planted will be utilized much more intensively than it was before, requiring more frequent fallow years in which corn fields are left unplanted
This does actually cast doubt on the conclusion. 作者: pennyz 时间: 2013-2-21 21:31

A new machine for harvesting corn will allow rows to be planted only fifteen inches apart, instead of the usual thirty inches. Corn planted this closely will produce lower yields per plant. Nevertheless, the new machine will allow corn growers to double their profits per acre because __________.
(A) with the closer spacing of the rows, the growing corn plants will quickly form a dense canopy of leaves, which will, by shading the ground, minimize the need for costly weed control and irrigation. Thus lower the cost and increase the profit.
(B) with the closer spacing of the rows, corn plants will be forced to grow taller because of increased competition for sunlight from neighboring corn plants. Irrelevant
(C) with the larger number of plants growing per acre, more fertilizer will be required. Irrelevant
(D) with the spacing between rows cut by half, the number of plants grown per acre will almost double.
This is the most attractive wrong answer. The passage already indicates that corns planted this closely will product lower yields per plant. So even if the number of plants per acre will almost double, there is no guarantee that the profits will double.
(E) with the closer spacing of the rows, the acreage on which corn is planted will be utilized much more intensively than it was before, requiring more frequent fallow years in which corn fields are left unplanted. Irrelevant作者: lyrsilvia 时间: 2013-9-21 18:58

Northern Air depends for its success on economy and quick turnaround and consequently is planning to replace its large planes with Skybuses, whose novel aerodynamic design is extremely fuel efficient. The Skybus' fuel efficiency results in both lower fuel costs and reduced time spent refueling.
逻辑:NA每天有很多航班,然后highly congested。NA的成功基于经济和quick turnaround,他计划用S替换大飞机。S燃油效率高,使得油费下降而且减少了时间
推测:反正就是讲S不好
Which of the following, if true, could present the most serious disadvantage for Northern Air in replacing their large planes with Skybuses?
(A) The Skybus would enable Northern Air to schedule direct flights to destinations that currently require stops for refueling. 加强
(B) Aviation fuel is projected to decline in price over the next several years. 无关
(C) The fuel efficiency of the Skybus would enable Northern Air to eliminate refueling at some of its destinations, but several mechanics would lose their jobs. 前加强 后无关
(D) None of Northern Air's competitors that use Belleville Airport are considering buying Skybuses. 无关
(E) The aerodynamic design of the Skybus causes turbulence behind it when taking off that forces other planes on the runway to delay their takeoffs. 正确

Which of the following most logically completes the argument?
A new machine for harvesting corn will allow rows to be planted only fifteen inches apart, instead of the usual thirty inches. Corn planted this closely will produce lower yields per plant. Nevertheless, the new machine will allow corn growers to double their profits per acre because __________.
逻辑:新机器可以使农作物种植距离减少一半,但是种的这么近农作物会减产。尽管如此,新机器还是会使农民受益加倍
推测:种的多或者是有其他好处,可以是C减少或是r增加
P=r-c
(A) with the closer spacing of the rows, the growing corn plants will quickly form a dense canopy of leaves, which will, by shading the ground, minimize the need for costly weed control and irrigation 虽然支持了结论 但是没有讲到倍数的问题
(B) with the closer spacing of the rows, corn plants will be forced to grow taller because of increased competition for sunlight from neighboring corn plants 长得高和profit关系还是蛮远的
(C) with the larger number of plants growing per acre, more fertilizer will be required 削弱
(D) with the spacing between rows cut by half, the number of plants grown per acre will almost double 正确 主要是结论里面还有倍数
(E) with the closer spacing of the rows, the acreage on which corn is planted will be utilized much more intensively than it was before, requiring more frequent fallow years in which corn fields are left unplanted 无关 作者: spencerchan 时间: 2016-1-29 11:27
