感觉很难的assumption&还是我误解?? - ChaseDream

A recent report determined that although only three percent of drivers on Maryland highways equipped their vehicles with radar detectors, thirty-three percent of all vehicles ticketed for exceeding the speed limit were equipped with them. Clearly, drivers who equip their vehicles with radar detectors are more likely to exceed the speed limit regularly than are drivers who do not.

(A) Drivers who equip their vehicles with radar detectors are less likely to be ticketed for exceeding the speed limit than are drivers who do not.

(B) Drivers who are ticketed for exceeding the speed limit are more likely to exceed the speed limit regularly than are drivers who are not ticketed.

(C) The number of vehicles that were ticketed for exceeding the speed limit was greater than the number of vehicles that were equipped with radar detectors.

(D) Many of the vehicles that were ticketed for exceeding the speed limit were ticketed more than once in the time period covered by the report.

(E) Drivers on Maryland highways exceeded the speed limit more often than did drivers on other state highways not covered in the report.

因为B使得33%的车子有装雷达的这个例子是"经常的" 而不是巧合
                所以结论可以说
                有安装雷达的车子比较容易超速
                对吗??

Traveler: Southern Airways has a far worse safety record than Air Dacentaria over the past few years, in terms of both the frequency of accidents and the severity of accidents. Therefore, although Air Dacentaria is slightly more expensive, I will choose it over Southern Airways for my flight from Pederton to Dacenta, since it is worth paying extra to have a safer flight.

Which of the following, if true, casts the most serious doubt on the traveler's argument?

(A) Air Dacentaria's flight from Pederton to Dacenta is nonstop, whereas Southern Airways' flight touches down in Gorinda on the way.

(B) Most Southern Airways flights, but not its flight from Pederton to Dacenta, use Sarmouth airport, which because of its mountainous location is one of the world's most dangerous.

(C) For its flights from Pederton to Dacenta, Southern Airways uses a different model of airplane, with a smaller capacity, than the model Air Dacentaria uses for its flights on the same route.

(D) Only in the last few years has the cost of flying from Pederton to Dacenta been more expensive on Air Dacentaria than on Southern Airways.

(E) Although the frequency of accidents is greater on Southern Airways, on both airlines the proportion of flights that have accidents is very small.

这题是要我doubt -较贵就会较安全
这个argument吗? 还是我看错题目意思??

2。 The argument is "I will choose Air Dacentaria even it's slightly more expensive because it has a better safety record than that of Southern Airways".

(A) actually strengthens the argument because the more connections the flight has, the more dangerous.

(B) weakens the argument by suggesting that the cause of bad safety record of Southern Airways is due to one of its major connection locates in a dangerous terrain. And since the fight from Pederon to Dacenta won't go through that route, it should be much safer.

所以，假设就要建立在罚款与超速上，所以就选B，是罚款——〉超速

这是属于搭桥型的假设，即前提A-->B，结论是A-->C,所以必须建立桥梁使得B-->C

以下是引用ken92在2007-12-17 14:00:00的发言：

所以这题是属於GAP 题型罗?
因: 被开单的人有雷达
结论: 有雷达的人易超速
Assumption: 被开单的人易超速
我这样推理对吗??
GAP题型吗?
