Criminologist: According to a countrywide tabulation of all crimes reported to local police departments, the incidence of crime per 100,000 people has risen substantially over the last 20 years. However, a series of independent surveys of randomly selected citizens of the country gives the impression that the total number of crimes was less in recent years than it was 20 years ago.
Which one of the following, if true, would most help to resolve the apparent discrepancy described by the criminologist?The discrepancy is that police reports show crime per 100,000 people has increased, but citizen surveys suggest the total number of crimes has decreased.
The key difference is that police data count only reported crimes, while surveys may reflect actual crime experience more broadly.
(A) Not all of the citizens selected for the series of independent surveys had been the victims of crime.
Wrong. That is expected in any crime survey and does not explain the conflict.
(B) Most crimes committed in the country are not reported to local police departments.
This helps only a little. It shows police data may be incomplete, but it does not explain why reported crime increased while survey-based crime seemed lower.
(C) The total annual number of crimes committed in the country has risen over the past 20 years but has fallen in proportion to the country’s growing population.
Wrong. This says total crimes rose, but the surveys suggest total crimes fell.
(D) In the series of independent surveys, many of the respondents did not accurately describe the crimes to which they had fallen victim.
Wrong. This suggests the surveys may be unreliable, but it does not clearly explain the specific pattern.
(E) Of crimes committed in the country, a much greater proportion have been reported to local police departments in recent years than were reported 20 years ago.
Correct. If more crimes are now being reported to police, then police records could show an increase even if the actual total number of crimes has fallen. This directly reconciles the
reported-crime increase with the survey-based decrease.
Answer: (E)
