Question

Although American Indian soldiers had effectively used their languages to create and transmit secret messages during World War I, military leaders were reluctant to use the code a second time, fearing that it would no longer be effective. The Japanese and German governments had sent students to the United States specifically to learn certain American Indian languages. The Navajo language, however, was so complex that few people outside the Navajo Nation itself could speak it. In 1942, it was estimated that only thirty non-Navajos spoke the language worldwide.
Which questions would improve the reader’s ability to understand the military leaders’ fear that the code would no longer be effective? Check all that apply.

How many people spoke Navajo before World War I?
Was the US government able to figure out other countries’ codes?
Why did the Navajos try to prevent outsiders from learning their language?
Did any of the Japanese or German students learn to speak Navajo?
What kind of code did the American Indians use during World War I?

Answer 1

Answer:

The answers are options C and D.

Explanation:

If the intention is to improve reader's ability to understand the military leaders' fear that the Navajo code would no longer be effective it is necessary to know if anny Japanese or German student learn the language; if they did so, it wouldn't have been possible to use it again; also, it would be logical to ask what kind of code was used by the American Indians during World War I; this way, the readers would know if enough precautions were taken by the military leaders about the new codes.
