the author of \code talkers\ supports the idea that the code talkers were essential to americas war effort by\n○ illustrating why the code talkers chose to help the us by creating a code.\n○ highlighting the complexity of the navajo language the code talkers used.\n○ highlighting the bravery of the soldiers the code talkers worked with.\n○ illustrating how the code talkers provided a specific service in a major battle.
Answer
Brief Explanations:
The most direct way to show code - talkers' essentiality is by demonstrating their specific service in a major battle. Illustrating why they chose to help doesn't directly show their importance to the war effort. Highlighting language complexity doesn't prove their necessity in the war. Highlighting soldiers' bravery doesn't relate to code - talkers' essentiality.
Answer:
D. illustrating how the code talkers provided a specific service in a major battle.
