Answer:
C. cause and Affect
Explanation:
actcion would be the cause and affect would be the consequence
The word prodigious means Immense.
The word desponding means Hopeless.
The correct answers would be questions D " Did any of the Japanese or German students learn to speak Navajo" and E " What kind of code did the American Indians use during World War I". These are the questions that could help the reader understand the military leader's fear, since if the answers are yes they did learn to speak it, and a simple code, (respectively) then it would be perfectly sane to feel apprehension at using the same code again. Options A, B and C are not relevant because they do not contribute to the subject, for example, it doesn't matter how many people spoke Navajo before World War I, what is important is how many can learn it.
Tips on writing essays:
-Don't be wordy. Use clear sentences, and write down the points you want to make beforehand so you know exactly what you need to write about.
-Don't be afraid to edit! Write a full story if you need to, and then clean it up when you're done writing to make it legible and precise.
-Don't focus on how many words/letters you've written so far. Write as much as you can, and then after you're done with the editing process add more if needed.
-Don't include sentences that don't support your main topic, that could get your grade lowered.
-Don't rush yourself, even if you're in a hurry. Your writing will come out sloppy and it'll be very transparent you just started working on it.
