Question

The Marquis de Lafayette helped George Washington during the American Revolution by sending supplies to Valley Forge. volunteering to join the British army as a spy. refusing to participate in the siege of Yorktown. convincing France to send 6,000 soldiers.

Answer 1

A French Marquis would make a rotten spy in the British Army. Refusing to fight in the most important victory of the American Army wouldn't help Washington. So you are down to two left.
Are you supposed to choose one or two?
