Final answer:
Major General Smedley Butler and Gunnery Sergeant Daniel Daly are the only two Marines to be awarded two Medals of Honor for their heroic actions during separate military interventions.
Step-by-step explanation:
The only two Marines to be awarded two Medals of Honor are Major General Smedley Butler and Gunnery Sergeant Daniel Daly. Neither John Basilone, Lewis Burwell Puller, James Williams, Thomas Baker, Jason Dunham, nor Dakota Meyer have received the Medal of Honor twice. Smedley Butler received his Medals of Honor for actions during the occupation of Veracruz in 1914 and the Haiti Occupation in 1915. Daniel Daly received his first Medal of Honor for his actions during the Chinese Boxer Rebellion in 1900 and his second for his actions in Haiti in 1915. Therefore, the correct answer to the student's question is: (b) Daniel Daly and Lewis Burwell Puller.
