OG 11 - CR - Q81

by Poornima » Mon May 26, 2008 5:29 pm
A recent report determined that although only 3 percent of drivers on Maryland highways equipped their vehicles with radar detectors, 33 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.

The conclusion drawn above depends on which of the following assumptions?

A)
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)
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)

I am unable to choose between B and D. The answer is B but I am not convinced. Can someone please help?

The word REGULARLY holds the key here. In option D, it is said that many of the vehicles that were ticketed were ticketed more than once. But this is out of the information given in the passage. There is no mentioning of how many times the vehicles have been counted. On this reason you can rule this out. In option B, it is clearly said that once ticketed the drivers tend to get ticketed again and again.... the word REGULARLY holds the key again.

Hi poornima,

choice D is rather strong in stating so, moderate is choice B. concentrate on the stimulus that states " drivers who equip their vehicles with radar detectors are more likely to exceed the speed limit regularly "

So, the best choice is B.

PerfectStranger,

Try to negate choice B.
If Drivers who are ticketed for exceeding the speed limit are not likely to exceed the speed again, the count of vehicles got ticketed wont be as high as 33%.

Hi ,

I understand B is right.
But here, if we try to apply negation on B, it probably doesn't work or becomes too abstract to understand and check if the conclusion falls apart.

So the takeaway should be that, we shouldn't always apply negation?
Regards,
Sach

Stem talks about the following: 3% of drivers equipped with radar, and 33% of all drivers who were ticketed for exceeding speed were with radar.

Conclusion : drivers who equip their vehicles with radars are more likely to exceed the speed limit than those who are not equipped:

Now option 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.

It clearly links the conclusion with the premise.

Always applying is a little to extreme. Check sensibly for the options where Negation technique can be applied.

I always don't apply the negation technique but when I'm stuck down to 2 options I generally use this rule.
