Final answer:
It is true that most rapes are committed by someone the victim knows.
Step-by-step explanation:
In a study of domestic violence incident reports, it was found that 29% of victims denied that abuse occurred when confronted by police. However, 19% of assailants were likely to admit to abuse. According to the National Criminal Victims Survey, victims may be reluctant to report abuse due to various reasons.
Statistics on intimate partner violence (IPV) can be difficult to determine as more than half of nonfatal IPV goes unreported. Victims of IPV often state that abuse had occurred for at least two years prior to their first report.
Therefore, it is true that most rapes are committed by someone the victim knows.
