GMAT OG逻辑题目解析第七题
Which of the following most logically completes the passage?
Most bicycle helmets provide good protection for the top and back of the head, but little or no protection for the temple regions on the sides of the head. A study of head injuries resulting from bicycle accidents showed that a large proportion were caused by blows to the temple area. Therefore, if bicycle helmets protected this area, the risk of serious head injury in bicycle accidents would be greatly reduced, especially since ______________________.
大部分自行车头盔能够很好的保护都得顶部和后部,但是且不能为头部两侧的颞部提供保护。一个自行车车祸造成头部受伤的研究显示,大部分的受伤都是由于颞部的撞击引起的。所以,如果自行车头盔能够保护这个区域的话,在自行车车祸中受伤导致头部严重受伤的风险会被大大降低,因为________________
(A) among the bicyclists included in the study’s sample of head injuries, only a very small proportion had been wearing a helmet at the time of their accident
在那些研究调查的自行车手当中,只有很小的一部分在出车祸的时候戴了头盔。
(B) even those bicyclists included who regularly wear helmets have poor understanding of the degree and kind of protection that helmets afford
即便是那些骑自行车经常带头盔的人对于头盔的保护能力也知之甚少。
(C) a helmet that included protection for the temples would have to be somewhat larger and heavier than current helmets
一个可以保护颞部的头盔比现在的头盔更大并且更沉。
(D) the bone in the temple area is relatively thin and impacts in that area thus very likely to cause brain injury
颞部的骨头相对较薄,对这个区域进行撞击很容易对大脑造成伤害。
(E) bicyclists generally land on their arm or shoulder when they fall to the side, which reduces the likelihood of sever impacts on the side of the head
骑自行车的人在出车祸的时候通常倒向一边压在他们的胳膊或者是肩膀上,这样会降低对头不造成伤害的可能性。
解析:
A 如果在调查的时候只有一小部分是戴了头盔的,那么文章中所得出的结论就不正确,并不一定是没有保护好颞部才导致的头部受伤,那么做出新的头盔也不一定降低头部受伤的风险。
B 人们了不了解头盔的保护能力和能否降低头部受伤的风险没有任何关系,无关选项。
C 头盔的重量和体积与需要解释的内容无关。
D 很好的解释了为什么颞部受到撞击容易导致头部受伤,也就加强了新的头盔可以降低头部受伤的概率的结论。正确答案。
E 人们会不会经常伤到头部和头部受伤是不是由于颞部受伤引起的没有关系,无关选项。
GMAT OG逻辑题目解析第八题
Hollywood restaurant is replacing some ofits standard tables with tall tables and stools. The restaurant already fillsevery available seat during its operating hours, and the change in seatingarrangements will not result in an increase in the restaurant’s seatingcapacity. Nonetheless, the restaurant’s management expects revenue to increaseas a result of the seating change without any concurrent change in menu,prices, or operating hours.
好莱坞的酒店把一些标准的桌子换成高的桌子和凳子。酒店在他开张的时候就已经充分使用了所用的空间放凳子,换桌子并不能增加酒店顾客的承载能力。然而,酒店经理预计换桌子的安排会带来利润的增加,并且在菜单,价位以及营业时间上并不会做出任何改变。
Which of the following, if true, providethe best reason for the expectation?
以下哪一项,如果成立的话,可以解释这种预期?
(A) One of the taller tables takes up lessfloor space than one of the standard tables.
高的桌子比标准的桌子占地空间少。
(B) Diner seated on stools typically do notlinger over dinner as long as diners seated at standard tables.
在新的桌子上吃饭的人逗留的时间并不像在标准的桌子上吃饭的人逗留的时间那么长。
(C) Since the restaurant will replace onlysome of its standard tables, it can continue to accommodate customers who donot care for the taller tables.
因为酒店不是把所有的桌子都换成高桌子,一些不喜欢做高桌子的客人也可以来吃饭。
(D) Few diners are likely to avoid therestaurant because of the new seating arrangement.
很少有客人会因为新的座位安排而不来吃饭。
(E) The standard tables being replaced bytall tables would otherwise have to be replaced with new standard tables at agreater expense.
高桌子替代了那些原本要花更多钱换成新的标准桌子的酒桌子。
【解析】
这是一道解释题,解释为什么酒店经理认为换成高的桌子会带来利润的增加。
A 文章已经说了换桌子并不能增加酒店顾客的承载能力,所以即便新的桌子占地空间小,也不能解释为什么利润一定会增加。
B 在新桌子上逗留的时间短,意味着饭桌率高,也就是说一定时间内在新桌子上吃饭的客人比在标准桌子上吃饭的客人要多,从而解释力利润为什么增加。是正确答案。
C 这只能说酒店可以维持原来的顾客,并不能解释为什么利润会增加。
D 也只能说明客人不会减少,不能解释利润为什么会增加。
E 只能说明花费方面节省了,并不能说明为什么未来会带来利润。
GMAT OG逻辑题目解析第九题
A major network news organization experienced a drop in viewership in the week following the airing of a controversial report on the economy. The network also received a very large number of complaints regarding the report. The network, however, maintains that negative reactions to the report had nothing to do with its loss of viewers.
一个很大的网络新闻机构在播出了关于经济的争议性报告之后,观众数量下降了。而且这个网络还收到了很多关于那个报告的控诉。然而,那个网络机构认为对那个报告的负面反应并不是造成观众大量流失的原因。
Which of the following, if true, most strongly supports the network’s position?
以下哪一项,如果成立的话,可以支持网络机构的观点?
(A) The other major network news organizations reported similar reductions in viewership during the same week.
其他的网络新闻机构在同一个周内经历了相同的观众的下降。
(B) The viewers who registered complaints with the network were regular viewers of the news organization’s programs.
那些对这个报告提出控诉的观众都是经常看那个新闻节目的观众。
(C) Major network news organizations publicly attribute drop in viewership to their own reports only when they receive complaints about those reports.
只有当新闻机构受到关于那些报告的控诉的时候,他才会把观众的下降归因于那个报告。
(D) This was not the first time that this network news organization has aired a controversial report on the economy that has inspired viewers to complain to the network.
这并不是这个新闻机构第一次因为播放了有争议性的经济报告而收到控诉。
(E) Most network news viewers rely on network news broadcasts as their primary source of information regarding the economy.
大部分的网络新闻的观众通常会把网络播放的新闻作为他们获得经济相关信息的首要信息来源。
解释:这是一道加强题,加强的观点是并不是因为播放了有争议性的经济报告而造成观众数量的下降。形似加强实则削弱。
A 这说明其他新闻机构都经历了观众数量的下降,也就是说观众数量的下降也就是说那个新闻机构的观众数量下降并不是由于报道了有争议性的经济报告,而是大趋势所致,他因削弱。正确。
B 是不是经常看的观众无关,无关选项。
C 这是更加说明观众数量的下降是由于有争议性的经济报道。
D 虽然提出了同因,但是没有说之前观众的数量有没有下降。
E 是不是首要信息来源并不重要,无关选项。
