12月GMAT逻辑新题精简版

1.蝙蝠和鸟的捕食能力
一个实验做了, 特别强调了实验的时间是某年的7月, 分了四个区, 一个不让蝙蝠进, 一个不让鸟进, 一个蝙蝠和鸟都可以进, 还一个什么来着, 结果发现那些让蝙蝠进的区域昆虫数量都显着下降了, 得出结论说蝙蝠对控制昆虫种群密度更有效, 问weaken;
蝙蝠在夏天捕食能力特别高 ---- 这个好象是strengthen
蝙蝠夏天的繁殖能力reproduce很强,这个倒是说明了单只蝙蝠的作用并不更大,所以weaken

2.机场运客轨道往东还是往西修    要自己有无登机(boarding),无法确定选项
V1一城市修建通往机场的rail,以缓解交通堵塞。有两个机场 W and E,但是rail只能缓解一个。因为60%的乘客去E 所以要rail通往E,问evaluate
E per fly的乘客数对比。 虽然E的总的多,但不一定乘客会聚在一起。交通堵塞也许不严重

V2因为去机场的路堵塞,政府考虑修新的地铁还是什么的,这个城市有2个机场,west and south, 政府只能修建其中一个路线。West 登机乘客占60%,所以建议修west的。问需要知道什么?
A需要知道两个机场乘客中只是转机(transit,change)的乘客的比例

3.fish and settlers
V1  
曾经great lake鱼很多时周围住的settlers很多,鱼少了住在湖边的人就少了。问flaw,湖被污染了

考古:
V1
某个种族靠打鱼为生,所以应该只住在渔产丰富的河的沿岸,可是发现有些人也住在现在渔产不怎么丰富的河边,说明鱼的分布后来变了。问weaken。

4卡车GWD变体  本题无法确定选项!
A:triple-trailers3节卡车太危险,又重又不好制动,总之很危险,所以应该禁止在高速上开,3个州都禁止
卡车的维护者:在这三个州中三节卡车事故低于(not greater than)普通的卡车,所以不应该禁止
问B的错  我好像选的"not greater than"不等于少于......  

考古  狗主人说:内容有相似,但问法绝对不一样,大家注意变体
GWD-28-Q17
In the nation of Partoria, large trucks currently account for 6 percent of miles driven on Partoria’s roads but are involved in 12 percent of all highway fatalities. The very largest trucks – those with three trailers – had less than a third of the accident rate of single- and double-trailer trucks. Clearly, therefore, one way for Partoria to reduce highway deaths would be to require shippers to increase their use of triple-trailer trucks.
Which of the following, if true, most seriously weakens the argument?
A): Partorian trucking companies have so far used triple-trailer trucks on lightly traveled sections of major highways only.
B): No matter what changes Partoria makes in the regulation of trucking, it will have to keep some smaller roads off-limits to all large trucks.
C): Very few fatal collisions involving trucks in Partoria are collisions between two trucks.
D): In Partoria, the safety record of the trucking industry as a whole has improved slightly over the past ten years.
E): In Partoria, the maximum legal payload of a triple-trailer truck is less than three times the maximum legal payload of the largest of the single-trailer trucks

3. Opponents of allowing triple-trailer trucks to use the national highway system are wrong in claiming that these trucks are more dangerous than other commercial vehicles. In the western part of the country, in areas where triple-trailers are now permitted on some highways, for these vehicles the rate of road accident fatalities per mile of travel is lower than the national rate for other types of commercial vehicles. Clearly, triple-trailers are safer than other commercial vehicles.
Which one of the following, if true, most substantially weakens the argument?
(A) It takes two smaller semitrailers to haul as much weight as a single triple-trailer can.
(B) Highways in the sparsely populated West are much less heavily traveled and consequently are far safer than highways in the national system as a whole.
(C) Opponents of the triple-trailers also once opposed the shorter twin-trailers, which are now common on the nation’s highways.
(D) In areas where the triple-trailers are permitted, drivers need a special license to operate them.
(E) For triple-trailers the rate of road accident fatalities per mile of travel was higher last year than in the two previous years.

5.引狼入园
某公园自从引入了wolf,另一x动物的存活高了,原因是wolf吃elks,恰恰elks是feed on x 动物,strengthen题,我选A.引入wolf后,elks数量decrease dramatically.

6.市政建设
经济学家发表言论:
有一些VOTER 投了市政建设的票,说明他们还是支持convention center 的expansion的,但是这个议案fail了,说明大多数人不希望在市政建设上花钱,所以近期政府把所有市政建设的资金都pull了这个做法是合理的
问weaken,虽然人们否定了convention center 的expansion,但是人们并不希望所有建设停止。

7.换电脑和工作效率  
一个公司最近准备换装更高级的电脑和更大的带宽来提高工作效率,
但是又有人说员工用新电脑都是去打游戏去了,所以达不到效果。
问:如果公司这样做,而且那个人的反对也确实存在,哪个可以support公司的目的的达成。
A:公司有一项政策明令禁止员工上班时间玩游戏
D:most corporations发现 性能更好的电脑以及大带宽和员工上班时间玩游戏的时间 没有必然联系
E:貌似说的是,公司以前发现 员工并不会利用电脑和带宽来玩游戏

8.storm and parking
winter storm比autumn storm更violent,但是在停车场车损坏的在autumn storm比在winter storm要多,问解释:
          A说夏天怎么怎么样容易把树枝挂断什么的
           E说人们在冬天的时候尽量避免把车停在树下 一定错
我觉得秋天有树叶更容易折断这个答案更靠谱(常识),

V2 By citibear 760
说某地冬天下雪比秋天猛,但是保险公司接到车辆被雪压的case秋天的多过冬天的,问原因。常青树evergreen tree冬天可以承受更多雪的

考古
V4 support 题.某个地方他们那里冬天的将雪量比秋天要大,然而秋天因为树枝被雪压断造成的汽车房屋伤害却比冬天的多。有人说是因为秋天的数上有叶子,比较容易积雪,所以比较容易折断。选一下哪一个支持这个观点:我选的是有一种常青树(evergreen tree叶子冬天和秋天一样多),它的树枝折断所造成的损伤在秋天和冬天数量基本一致。

9.male or female fish
V2:一种male fish是一种主菜很赚钱,餐馆狠心老板说要给小female喂激素让他们长male的。因为malefish很好吃什么东东比较多。这样就能赚大钱。问WEAKEN 问不能达到效果的原因:
A female不能变成male
D这样变成male的鱼 有点苦不好吃
E说激素涨钱了

10.屋顶节能 加强或者weaken都选冬天能保暖的
V1有一个题是 因为天花板上的S什么东西的 吸热   然后导致了夏天空调费上升   为了节省能源费用in order to reduce annual cost 所以人们要把这个S东西换成##东西(名字忘记了)##东西用的能源比较便宜  问weaken 冬天来了  用S东西供热的能源费小于##东西  
高楼层搭草坪
V1 from 阿拉蕾捉鱼 (710)
有一个公司因为地处的楼层较高,summer经常日晒,空调费很贵。于是他们想在楼顶搭个草坪,可以减少费用。问加强
一个选项是这些年的夏日温度基本幅度不大
一个说冬天也可以省暖气费
一个说一些公司纷纷效仿,还在窗子外面装了。。。。
V4 from weirui5621 (770)
这个貌似没的选,别的太扯了,只能选那个冬天也能节省cost的
V5 from myr521 (750)
裸机有roof garden,选了冬天能保暖的那个选项,这个我要说明一下,因为题目中清清楚楚地写in order to reduce annual cost(目的),所以这么看来冬天这个恰恰从另一面起到了很好的加强作用哦
