@Jeshelto33 For group 2 indicators (which must belongs to), the idea immediately following the indicator is the necessary condition. So, "must be a force user" makes "force user" the necessary condition, putting it to the right of the arrow

For D where he changed decrease to increase, how would the answer potentially be correct? Would that not be following the logic (or arrow) backwards? It reads as a causation type of thing for me.
