How were alliances formed? Was one alliance stronger than the other ? Explain

Alliances are formed between nation-states and their proxies in order to wage war against common adversaries. Alliances are essentially agreements  to combine military and economic assets in pursuit of political objectives.  When alliances are formed, one alliance is not always stronger than the other.  The other alliance may have better resources or millitary.

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
