World War 1 Practice Test

The immediate effect being tested is the stoppage of a rapid German push into France. The First Battle of the Marne halted the German advance on Paris, forcing a retreat and breaking the momentum of the Schlieffen Plan.

In the short term, this meant no quick German victory and no swift Allied invasion of Germany; instead, it ushered in years of brutal stalemate.
