Your selections of c (seeing violence done to others) and d (being in an environment where violent behavior is tolerated) are correct as both factors can increase the likelihood of violence. Additionally, a (drug abuse) is also known to be a significant factor that can lead to violent behavior.
Therefore, the correct responses to select are:
- a (drug abuse)
- c (seeing violence done to others)
- d (being in an environment where violent behavior is tolerated)
b (attending afterschool stress management classes) would generally be considered a protective factor against violence rather than something that increases it.
