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. Ttherefore, 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? ['The argument fails to take into account that residents of County Y may be more law-abiding overall.', 'The argument fails to take into account that the speed limit may be different in the two counties.', '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.', 'The argument fails to take into account that a single driver can receive more than one ticket in a given year.']
