Explanation:

The text mentions "special shells" that explode silently, have no smell, and cause symptoms like dizziness, foaming at the mouth, skin discoloration, and death. These are characteristics of chemical warfare. Chemical weapons were used in World War I, and soldiers were supposed to wear masks to protect against them. The mention of a mask and the symptoms described align with chemical warfare.
For the second question, the Zimmermann Note proposed an alliance between Germany and Mexico. Germany hoped that if the United States entered the war, Mexico would attack the U.S. in return for territorial gains (such as Texas, New Mexico, and Arizona).

Answer:

First question: chemical warfare
Second question: an alliance between Germany and Mexico
