How did the wagon train party communicate with people who were far away, (the donner party.)

The Donner party left Springfield, Illinois, in April 1846. Led by two wealthy brothers, Jacob and George Donner, the emigrants initially followed the regular California Trail westward to Fort Bridger, Wyoming. From there, however, the emigrants decided to leave the established trail and take a new and supposedly shorter route to California laid out by an unscrupulous trail guide named Lansford Hastings. Hastings was not at Fort Bridger at the time–he was leading an earlier wagon train along his new route. He left word for the Donner party to follow, promising that he would mark the trail for them.

Explanation: not sure but hope it helps

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
