On
average,
the number of speeding tickets issued in County X every year is three times greater than the number of speeding tickets issued in County Y during the same period.
Therefore,
the number of people who exceed the speed limit must be higher in County X than in County Y.
Which of the following describes a flaw in the reasoning above?
A) The argument fails to take into account that the speed limit may be different in the two
counties.
IRRELEVANT - Immediately eliminateb) The argument fails to take into account that the number of tickets issued in County X may
reflect a lower proportion of drivers overall in that county.
Last option to be eliminated - This would be relevant if the conclusion was "People are country X are drive rashly as compared to people in country Y" or something similar to this.c) The argument fails to take into account that a single driver can receive more than one ticket
in a given year.
CORRECT ANSWER - If a single driver receives more than 1 ticket then the conclusion may not be true. For eg-
Number of Tickets - Country X = 10
Number of Tickets - Country Y = 5
Number of People who got Tickets in Country X - 1 (same person got ticket 10 times)
Number of People who got Tickets in Country Y - 5 (all tickets to different people)
In this case, the conclusion will not be true and this option points out this flaw.
d) The argument fails to take into account that residents of County Y may be more law-abiding
overall. -
