Arecent 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) 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 limitwas greater than the number of
vehicles that were equipped with radar detectors.
(D) Many of the vehicles that were ticketed for exceeding the speed limitwere 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.
Now I narrowed to B & D Below is my thought over this :-
conclusion: drivers who equip their vehicles with radar detectors are more likely to exceed the speed limit regularly
Premise: (1)3% of maryland dr have radar detectors.
(2)33% of all speeding tickets were issued to drivers with vehicles equipped with radar.
Lets try to negate B:
Drivers who are ticketed for exceeding the speed limit are NOT more likely to exceed the speed limit regularly than are drivers who are not ticketed
As the conclusion has word "regularly" it means the drivers who exceed speed limits do so regularly.So B destroys the conclusion.
Negating D:
Many of the vehicles that were ticketed for exceeding the speed limit were NOT ticketed more than once in the time period covered by the report.
It looked close to me unless I took an example :
Now to prove that D is not neccessary for the conclusion to hold true , any one case should be enough.
1000 vehicles in Maryland - 30 equipped with radars
Say 90 speding tickets in the report - 33% are equipped with radars - 30. So it might be possible that each vehicle is ticked only once.So D is not an assumption.
Please correct me if I got it all wrong!
