Answer :
Final answer:
The importance of the message sent by Zimmermann is indicated by its route and method of delivery.
Explanation:
The evidence from the excerpt indicating the importance of the message sent by Zimmermann is:
- The route the telegram was supposed to take, first to Sweden and then to Washington, D.C., supports the idea that the contents of the message were important.
- Because the message was crucial and needed to reach von Bernstorff, Zimmermann opted for it to be carried across the ocean in a U-boat.
The destination and the method of delivery emphasize the significance of the message in attempting to involve Mexico in supporting Germany during the war.
