Language Arts
I am a French student studiying in an american international section.
We recieved an assigment from ous Language Art teacher, which goal was to find a main question in link with the several lines of study we did and answser it relying on articles we found on Internet.
My question was mostly about war and conflict, and the role of human nature in those. Basically, are humans predestined to war?
According to my researches, the answer is no. Conflits is part of us, but conflict and war or violence are not exactly the same. There’s a nuance. It’s a matter of degree. Warfare is an human invention and not a necessity.
I related my researches and my main question to images in this collection using thinking routines that really does help in focusing on certain aspects of an image you want to analyse.
