- In the last four years, crime dropped significantly, especially crimes by career criminals.
- Find the statement that best explains why crime dropped after the initial two years.
Answer Choices Analysis:
(A) 40% of similar-sized cities reported a drop in crime over the last four years.
This provides general information but does not explain the specific change in Harrisville’s crime rate.
(B) Harrisville's population increased, especially with senior citizens moving into the city.
An increase in senior citizens may affect demographics but does not directly explain the decrease in crimes by career criminals.
(C) By the end of the second year, most career criminals in Harrisville were captured and incarcerated.
This directly explains the reduction in crimes by career criminals during the last four years, as they were no longer operating in Harrisville.
(D) Local high schools had increased retention and graduation rates over the six years.
While improved education may contribute to lower crime rates long-term, it does not specifically explain the drop in crimes by career criminals after the first two years.
(E) Police started daytime foot patrols downtown two years after the change.
Daytime foot patrols could have contributed to crime reduction, but this does not specifically address crimes by career criminals or explain why the drop occurred after the first two years.
Correct Answer: C
The incarceration of most career criminals by the end of the second year directly explains the significant drop in crime during the last four years.
