Answer :
Final answer:
The significance of the message sent by Zimmermann to von Bernstorff was demonstrated through the route chosen for delivery and its content.
Explanation:
The evidence from the excerpt leads to the inference that the message Zimmermann sent was important because:
- The route the telegram was to take, first to Sweden and then to Washington, D.C., demonstrates that the contents of the message were significant.
- Zimmermann's decision to use a U-boat to ensure the message reached von Bernstorff emphasizes the importance of the communication.
- The fact that the message aimed to influence Mexico to aid Germany in the war underscores its significance.
