Final answer:
Without a specific and authoritative source, the claim that 20% of youths have brought a weapon to school remains unverified. Various studies report on related issues such as bullying and gun violence in schools, underscoring the importance of school safety.
Step-by-step explanation:
The claim that 20% of youths have brought some sort of weapon to school cannot be verified as true or false without a specific and reliable source of information that directly addresses this statistic.
However, various reports and studies have highlighted concerns about youth violence and safety in schools.
For example, the National Center for Educational Statistics reported in 2013 that about 27.8 percent of students report being bullied at school, and 17 percent of students reported being victims of cyberbullying.
Additionally, discussions around gun violence in schools have been prevalent, especially after several high-profile school shootings.
Advocates for stricter gun control note a relationship between access to guns and mass shootings, while others argue that there are different contributing factors.
With regard to the student's specific question about the presence of weapons in schools, it is important to consult updated and authoritative sources to understand the current situation as it may have changed since past reports.
More recent studies or surveys might provide a clearer picture of the current trends in school safety and weapon possession among youths.
