Explanation:

• "Swiss invasion of Belgium" is incorrect as Switzerland was neutral and it was Germany that invaded Belgium.
• "to demand reparations from Germany" was a post - war (WWI) action, not a reason for U.S. entry into the war.
• "British Sinking of the Lusitania" is incorrect; it was a German U - boat that sank the Lusitania.
• The Zimmermann Telegram, where Germany proposed an alliance with Mexico against the U.S., was a key reason for the U.S. to enter World War I.
