How was the dropping of the atomic bomb in japan courageous?

Well for starters it showed a determination by the US to win this battle and no sacrifice troops. It showed its power to the world knowing that Russia could have shown its power. It wasn't even sure if Japan was going to surrender... All of these should do.. Pick and choose

i would think it's industries and hydroelectric power

i think the answer is c, rivers.

explanation:

sometimes, borders fall along natural boundaries like rivers or mountain ranges. for example, the boundary between france and spain follows the crest of the pyrenees mountains. for part of its length, the boundary between the united states and mexico follows a river called the rio grande. the borders of four countries divide africa’s lake chad: niger, chad, cameroon, and nigeria.
