Answer

Brief Explanations:

The Zimmermann Telegram, intercepted by Britain in 1917, proposed a German - Mexican alliance against the US. Germany's resumption of unrestricted submarine warfare in 1917 directly threatened US shipping interests. These were key events leading the US to enter WWI. The sinking of the Lusitania was in 1915, Mexico did not attack the US on US soil, and Britain and France asking was not a decisive factor in 1917 for US entry.

Answer:

Britain intercepted the Zimmermann Telegram. Germany resumed unrestricted submarine warfare.
