Discuss the ways in which the mongol imperium enhanced contacts, particularly between china and the islamic world. which areas received the most benefit from these exchanges?

 Mongol invasions ended or interrupted many of the great empires of the post classical period, while also extending the world network that had increasingly defined the period. Under Chinggis Khan - who united his own Mongol tribesmen and numerous nomadic neighbors into the mightiest war machine the world had seen to that time - central Asia, northern China, and eastern Persia were brought under Mongol rule. 

hello!

according to the passage the most suitable options are two. the first one is "by leading the aef to victory in several key battles" like the battle of saint- mihiel and the battle of cantigny mentioned in the passage you copied here. the second one is "by the aef and allied forces defeat germany" since the passage says that his army destroy the german resistance in the meuse- argonne offensive. and also, "by insisting that the aef operate as an independent force".

hope this
