Hi There!
Question - Cryptology, the study and use of secret codes, has been an important component of US military strategy since it was first used in the American Revolution to hide sensitive communications from British forces.
How does the author introduce the reader to code talkers?
Answer - by presenting an interesting fact
Why - The reason I say its option A is because the fact that it makes the most sense in a way that, the other options don't make any sense. Option B says telling an entertaining story when its not a story. Option C makes no sense because the first sentence dosen't contain a quotation. Option D makes no sense because the first sentence dosen't ask a question.
Hope This Helps :)
It can identify(if you know who is narrating) to tell you if you are in third person or first person or it can identify who is the narrator if you know what person you are writing in. The second person should never be used in a narrative essay. That would be informal and incorrect. You can also identify when it is taking place in some cases............. I don't know if this helped but I tried
The error is in the first sentence- “shine brightly” should be “shines brightly” because the subject is singular.
