gre argument 239题目：
The following appeared as an editorial in the local newspaper of Dalton.
"When the neighboring town of Williamsville adopted a curfew four months ago that made it illegal for persons under the age of 18 to loiter or idle in public places after 10 p.m., youth crime(2) in Williamsville dropped by 27 percent during curfew hours(1,2). In Williamsville's town square(5), the area where its citizens were once most outraged at the high crime rate, not a single crime has been reported(4) since the curfew was introduced. Therefore, to help reduce its own rising crime rate, the town of Dalton should adopt the same kind of curfew(6,7,8). A curfew that keeps young people at home late at night will surely control juvenile delinquency(9) and protect minors from becoming victims of crime(10)."
(1)We are not informed about the variation in crime committed before curfew hours.
(2)We do not know if crime of other type also dropped since the curfew was introduced.
(3)The decline in Williamsville's overall crime rate is not necessarily attributable to the curfew.
(4)We do not know how many crimes were committed at the town square but not reported.
(5)The amelioration of the town square may not be representative of the situation of the entire town.
(6)We do not know what fraction of all crime in Dalton is youth crime, thus could not evaluate if the same kind of curfew will also be effective in Dalton.
(7)Dalton might differ from Williamsville in ways that would undermine the curfew's effectiveness in Dalton.
(8)There are many other ways to reduce Dalton’s crime rate.
(9)Granted that the proposed curfew would reduce Dalton's overall crime rate, the author unfairly infers that the curfew would also curb juvenile delinquency.
(10)Crimes against youths might occur during non-curfew hours, thus the inference that the curfew would protect minors from becoming crime victims is unwarranted.
