I'm pretty sure A is the secondary source. All of the others come directly from the source/person, but an interview is getting someone else's view.
Answer: B. Spread of the bubonic plague.
Explanation:
The spread of the Bubonic Plague or the Black Death has nothing to do with the Mongols. Scientists speculate that the first wave of the disease arrived in Europe by sea trade routes from Asia to Italy. Italy has been a center of European trade for a long time, and the diseases were transmitted to the mainland by infected ship rats. The plague ravaged Europe on several occasions, and in the first wave, half of the European population died as a result of the infection.
That would be A, and abundance of Natural resources. The United States was still pretty new when the industrial revolution started, so they had a huge amount of natural resources at their disposal, unlike Britain that had been there for way way longer. Hope this helps! I’m new on here.
I find it important to lead because I have a strong passion for it, I believe I have the skills and leadership to be a leader.
Did this help?? if not sorry
