In the Featured Study on Youth Suicide in Canada's First

In the Featured Study on Youth Suicide in Canada's First Nations, the purpose for the research was to identify factors that might differentiate among high- and low-risk communities. Why is this differentiation important?

A) The risk of suicide is high among adolescents in general and this trend is seen to a similar extent among First Nations youth.
B) Although the risk of suicide among First Nations youth is the highest of any cultural group in the world, there is a great deal of variation across bands and some bands even have a rate of zero.
C) Although the risk of suicide among First Nations' youth is typically very low, there are some communities that appear to have an increased risk.
D) The risk of suicide among First Nations youth is lower than the national average, and the protective factors associated with this reduced risk may help researchers to prevent suicide in non-First Nations.
