This question uses a very classic logic assumption – Statistical Assumption
. It is similar to hypothesis you see in Probability & Statistics of Quantitative. The form is:A is more likely to do X than B is
Assumption: Over the statical period, A does X more often than B does.For example:
Team A has more chances to win this game than Team B does.
Assumption: Over the statical period, Team A wins more often
than Team BMore example:
Mount A is more likely to have volcano than Mount B is
Assumption: Over the statical period, Mount A has volcano more often
than Mount BAPPLY TO THIS QUESTION:
Fact: only 2 percent of drivers on Lalaland’s highways drove sports cars,
Fact: 25 percent of all vehicles ticketed for drunk driving in the past 90 days were sports cars.
Conclusion: Sports car drivers on Lalaland highways are more likely to drive drunk than are drivers of other kinds of vehicles.Assumption:
Over the statical period, sport car drivers drives drunk more often (more regularly)
than drivers of other kind of vehicles do.ANALYZE EACH ANSWER:
A)Drivers on Lalaland highways drive drunk more often than do drivers on highways not covered in the report. Wrong.
Out of scope. Nothing about “drivers on highways not covered…”. We just talk about Lalaland highways.
B)Many of the vehicles ticketed for drunk driving were ticketed more than once during the time period covered by the report.Wrong. TEMPTING.
Why? The wording is quite simple, but if you do not read carefull, you may assume “many of the vehicles ticked for drunk driving more than once” are “sport vehicles”. However, B is wrong because B does not say these vehicles are sport cars
. If that was the case, B would be correct assumption. But what if the vehicles ticked for drunk more than once may NOT be sport cars.
C)Drivers who are ticketed for drunk driving are more likely to drive drunk regularly than are drivers who are not ticketed. Correct.
This is exactly assumption stated above.
D)The number of drivers ticketed for drunk driving was greater than the number of sportscars. Wrong.
We do not compare the number of drivers vs the number of sportcars.
E)Drivers of sports cars are less likely to be ticketed for drunk driving than are drivers of other kinds of cars.Wrong.
It’s a reverse answer. Hence, E is wrong.
Hope it helps.
