If I wanted to design an app for world peace, what problems could a computer help me to solve? Select ALL that apply * A. Ranking countries and their peacefulness based on war history, taking into consideration World War participation, Civil Wars, number of years at war over the last 100 years, and total deaths as a direct result of war over the last 100 years

B. Create a forum where people wanting to promote world peace can meet and discuss strategies.

C. Design an interactive map where people can see where war is taking place

D. Make the leader of a country change his/her mind about going to war

E. Stop a war that is currently happening

I believe B is the correct answer.

Explanation:

A is quite useful, but it's not necessary for our goal of world peace.

E is too vague and doesn't help the cause. How do you simply 'stop a war' and how can we ensure that more wars won't arise in the future?

D does stop a war from going on, but it doesn't solve the problem of wanting world peace, as more wars can arise in the future.

C, as the idea, is really cool, again, how will it help our cause of wanting world peace?

I understand that you can choose multiple answers here, but you can't simply change one's mind just for the sake of wanting peace. Wars are a problem and do take part in world peace, but that doesn't change the fact that someone is not at peace with others. You've got to change their minds, not just the idea of wanting to go to war.

Please, do tell me if I got this incorrect.
