Question

in return for ending unrestricted submarine warfare, germany wanted the united states to: a. stop shipment of arms to britain. b. return territory to mexico. c. join the central powers. d. help end the british blockade.

Explanation:

To solve this, we analyze each option:

• Option A: Germany's unrestricted submarine warfare was partly to counter British supply lines. Ending it in return for US stopping arms to Britain aligns with their strategic goal.
• Option B: Returning territory to Mexico was part of the Zimmermann Telegram (asking Mexico to ally against US), not related to ending submarine warfare.
• Option C: US joining Central Powers was not a demand for ending submarine warfare; US later joined Allies.
• Option D: Germany wanted to break British blockade, but asking US to help end it isn't the main demand for ending submarine warfare.

Answer:

D. Help end the British blockade.
