Citizen: Each year since 1970, a new record has been set for the number of murders committed in this city. This fact points to the decreasing ability of our law enforcement system to prevent violent crime. City official: You overlook the fact that the city' s population has risen steadily since 1970. In fact, the number of murder victims per 100 people has actually fallen slightly in the city since 1970. Which one of the following, if true, would most strongly counter the city official's response? ['If the health care received by assault victims last year had been of the same quality as it was in 1970, the murder rate in the city last year would have turned out to be several times what it actually was.', 'The incidence of fraud has greatly increased in the city since 1970.', 'Murders and other violent crimes are more likely to be reported now than they were in 1970.', 'The rate of murders in the city since 1970 decreased according to the age group of the victim, decreasing more for younger victims.']
