During the battle of the Marne why was Germany forced to take some of its army away from France

b. british workers

according to my research (britannica and quizlet) the first settlements were along the huang river because it could give the crops more fertile soil that really it out. this was due to the yellow slit caused by floods of the river.

i believe the answer is the last option, the magyars preferred to invade by land.

i hope this ! : )
