Question

Before World War I, France and Russia had a military alliance. This meant that
each country promised to support the other in the event of war. In 1914,
Germany declared war on Russia. By the end of the year, both French and
Russian troops were battling the German military. Which of the following, if
true, would suggest that the military alliance was the cause of France
entering the war with Germany?

Answer 1

If France and Russia formed an alliance it would mean that either one of them would join any battle that either country was facing so it would only make sense for France to enter the war with Germany.

Answer 2

France did not declare war on germany until germany attacked france.
