A time when new inventions such as
the seed drill and the steel plow made farming easier and faster. The
production of food rose dramatically.

I know but what am i supposed to answer?

Do you need any help?

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
