While researching a topic, a student has taken the following notes:
• In World War I, US soldiers who were members of the Choctaw Nation in Oklahoma participated in the Choctaw Code Talkers program.
• The Choctaw Code Talkers were trained to relay coded military information in their native language.
• In World War II, the US Army recruited Navajo (Diné) soldiers to transmit coded messages in their native language.
• These soldiers were known as the Navajo Code Talkers.
The student wants to emphasize a similarity between the Choctaw Code Talkers and the Navajo Code Talkers. Which choice most effectively uses relevant information from the notes to accomplish this goal?
