How were u. s. troops primarily used in world war 1?
a). to launch an offensive to end the war
b). to replace civilian workers in wartime industries
c). to replace wounded allied soldiers not the western front
d). to provide protection for supplies being transported to the front lines

This is a hard one...  but I believe it is either C or D. We know that wounded Allied soldiers were a big issue during the war and a big reason as to why the U.S. joined was to gain land and protect its allies that it related to (mainly being Britain). D is also a reasonable answer, but I highly doubt it is the other options. Double check your history book, but I think the answer is C.

hitler was elected as a strong leader by germans who felt angry following the treaty of versailles.

the correct answer is option d

the economy will face inflation
