5. The violent crime rate (number of violent crimes per 1,000 residents) in Meadowbrook is 60 percent higher now than it was four years ago.  The corresponding increase for Parkdale is only 10 percent.  These figures support the conclusion that residents of Meadowbrook are more likely to become victims of violent crime than are residents of Parkdale.
The argument above is flawed because it fails to take into account

B how the rate of population growth in Meadowbrook over the past four years compares to the corresponding rate for Parkdale

D the violent crime rates in Meadowbrook and Parkdale four years ago

6. Tourists have long complained that hotel accommodations in Midville are too expensive.  Starting last year, the city council, hoping to attract more tourists, lowered the hotel tax rate to 5 percent of room charges.  By the end of last year, Midville had taken in no less money from hotel taxes than it did the year before, so an examination of the hotel records will show that more tourists stayed in city hotels last year than the year before.
Which of the following is an assumption on which the argument depends?

C The average length of a tourist’s stay in Midville hotels was not longer last year than it had been the year before.

E On average, tourists in Midville did not spend significantly more on meals last year than they did on hotels accommodations.
