Which of the following is the best example of a political conflict?

As noted above, some political conflicts do not offer opportunity for activist engagement, but many do. Indeed, some of the conflicts that have been most frequently studied using conventional models are ones in which youth activism was a vital component of the conflict (but it has gone unmeasured). The best example of this is research on Palestinians. Of literally dozens of studies conducted on Palestinians in the occupied territories that have assessed conflict exposure and its impact, very few have attended to the activism component of youth experience.  

the correct answer would be true friction causes the faults to slip or collide
