Which detail from the text supports the idea that the fiction author altered the historical facts?

it is the background information on the characters and setting explained at the beginning of the story. the exposition will often have information about events that happened before the story began. the exposition is often the very first part of the plot.

well basically since ima beginner people will answer any subject "right away"and if you get more points you could ask more questions or if you answer someone's question you get points

i cannot see any of the options        

plagiarism can get you expelled from your course, and college, or university. plagiarism can result in legal action like fines and penalties etc.
