timofeeve [1]

Answer:

Answer is Option A: Nations fell victim to new hostile leaders. Japan struck first, invading China. Next Italy struck at Ethiopia. Germany, under the leadership of Adolf Hitler, was the greatest fear.

America actively traded with Europe. They were helped by China in trading activities. Nazi's Germany was also becoming a threat for America under Hitler. So, they chose to stay out of the war.

They only entered the war after the Pearl harbor attack by Japan.

Why is it Important for scientists to defend their claims and conclusions to their peers
Margaret [11]
I think it's important because scientists need to be able to communicate. 
Think about why you write a lab report. When we write lab reports, we are effectively communicating how we did our experiment, our results, and what we think about those results. 

We need to have transparency and be able to replicate results in order to know if they are accurate to our hypothesis. Theories are not 100% proven. We only know what we are able to observe and all measurements have their limitations.
