Use the passage below to answer the question On April 22, 1915, the Germans launched their first and only offensive of the year. Now
referred to as the Second Battle of Ypres, the offensive began with the usual artillery
bombardment of the enemy's line. When the shelling died down, the Allied defenders
waited for the first wave of German attack troops but instead were thrown into panic
when chlorine gas wafted across no-man's land and down into their trenches. The
Germans targeted four miles of the front with the wind-blown poison gas, decimating
two divisions of French and Algerian colonial troops. The Germans, perhaps as shocked
as the Allies by the devastating effects of the poison gas, failed to take full advantage,
and the Allies managed to hold most of their positions.
What technological advancement gave Germany the advantage during the battle
described above?
A
Artillary bombardment
B
German attack troops
C.
Chrorine Gas
D
An infrantry assault
