Question 1:

          Provinces and states with stringent carsafety requirements, including required use of seatbelts and annual safetyinspections, have on average higher rates of accidents per kilometer than doprovinces and states with less stringent requirements. Nevertheless, mosthighway safety experts agree that more stringent requirements do reduceaccident rates.

        ?Which one of the following, if true,most helps to reconcile the safety experts' belief with the apparently contraryevidence described above?

?A) Annual safety inspections ensurethat car tires are replaced before they grow old.
?B) Drivers often become overconfidentafter their cars have passed a thorough safety inspection.
?C) The roads in provinces and stateswith stringent car safety programs are far more congested and thereforedangerous than in other provinces and states.
?D) Psychological studies show thatdrivers who regularly wear seatbelts often come to think of themselves asserious drivers, which for a few people discourages reckless driving.
?E) Provinces and states with stringentcar safety requirements have, on average, many more kilometers of roads than doother provinces and states.


Question 2:


?Calories consumed in excess of thosewith which the body needs to be provided to maintain its weight are normallystored as fat and the body gains weight. Alcoholic beverages are laden withcalories. However, those people who regularly drink two or more alcoholicbeverages a day and thereby exceed the caloric intake necessary to maintaintheir weight do not in general gain weight.

?Which one of the following, if true,most helps to resolve the apparent discrepancy?

?A) Some people who regularly drink twoor three alcoholic beverages a day avoid exceeding the caloric intake necessaryto maintain their weight by decreasing caloric intake from other sources.
?B) Excess calories consumed by peoplewho regularly drink two or three alcoholic beverages a day tend to bedissipated as heat.
?C) Some people who do not drinkalcoholic beverages but who eat high calorie foods do not gain weight.
?D) Many people who regularly drink morethan 3 alcoholic beverages a day do not gain weight.
?E) Some people who take in fewercalories than are normally necessary to maintain their weight do not loseweight.

第二题应该是B，跟一朋友探讨了下。。。唉，我真是失败。

第一题D。第一题是换着说法的加强题或者支持题，但他提了个要求，是只能建立在题中的证据上。所以选项中不涉及到题中证据的都可以先排除。
C 首先排除。
A 只是说了大家都会做的事，谁会等轮胎很新的时候换？但这个是小支持，因为太过隐晦了，题中并未确切说轮胎与车祸率的关系。但经常保持轮胎的功能正常确实能保证减少“一点点”的交通事故。
B 这是削弱，它明显点出了车检之后驾驶员可能存在的负面反映。
E 就算公里数开得再多也不会影响结论，因为题中说的是“每公里”。
D 大支持，明显点出了题中证据不说，还下了结论：那些驾驶员会少了些鲁莽行为（从而车祸率能得改善）。

第二题A。
逻辑链我是这样的。
背景：卡路里吸收太多会胖。
证据逻辑链：喝酒太多也会吸收多余的卡路里-----》从而变胖。
结论逻辑链：没有变胖《-----即便喝酒了也没多吸收卡路里（理由只有一个，卡路里总体吸收不多）。
对比选项：
A 成立，卡路里总体吸收少，所以就算喝酒喝死也不会怎样。
B 乍看很对，但是是个很具迷惑性的选项。这个选项的错误在于它否定了题中的一个论据。题中的论据说多余的卡路里是储存为脂肪，从而增重。但这选项说多余的卡路里被挥发成热能。明显与题目不相符。
CDE，几乎是一个套路，都只是很普通的陈述，完全不具备说明性。

1、专题解释，感觉挺全了。（针对A Vs B，比较有针对性）
http://forum.chasedream.com/GMAT_CR/thread-473925-1-1.html

2、一月份的逻辑小分队有题，楼里有该题逻辑链分析。可参照。

应该够了~此处就不粘贴了哈，同学点击一下看解释，比较全哈~

第二题我觉得排除最后剩下 AB 比较有竞争力，我自己觉得A好，B说的，摄入的被热量形式散发掉了，但看灰常合理啊，但是回到原文题干，有点无关选项嫌疑吧，谁说其他形式的卡路里摄取不能再给以heat散发掉？没有说，我觉得不够有力这个选项。
但是A如果在这个摄取途径中获得了，避免在其他方向获得，也说了是exceed，最后虽然人家喝酒摄入了卡路里但是人家avoid其他的exceed 摄入。总量实际上少了。就不会变肥肥鸟～～不知有木有道理～～捂脸跑走～

在这题目上，我的确比较赞同你的观点。我也是比较倾向A
A的话就说，有摄入多的，别的地方就少。
B感觉他dissipate as heat不和整体caloric intake没啥太多的关系的感觉

严格的要求使得安全性增加
实际上要求的越严格的state，事故增多了
专家依然觉得，越严格，可以减少事故的发生？
为嘛呢？ 看C说的，道路super 拥挤，事故容易发生，解释了现象矛盾所在，再者，要求更加严格后，大家懒得去做检查，种种，so更加严格的情况下，上路的少了~~情况得以缓解~~两方都顾及到了~~这是我的想法~~眨眼睛~

嗯，的确认为会比E的解答要好一些。。。
那您能帮我看看第二题吗？

已经更新了题目，谢谢。能给出理由为什么第一题选择C吗？

cecilia王

第二个没给出问题，第一个，窃以为C~~
