Expository text gets to the point rather quickly. It is intended as education rather than just narrative text. An example of narrative text is the Excerpt by Charles Dickens which is meant to draw a picture of what this woman was like.
So the last one is out.
The first one talks about volcanoes and how they are classified. That's one of your answers if you are trying for brevety and education.
I think the second one would also be a choice. It is trying to show you the nature of anxiety and what causes it. You learn a lot about symptoms from reading it. It's quick and to the point. Expository? Yes.
I don't think four is exactly expository, but I might be wrong. It sounds too argumentative to be completely expository. It wouldn't be my first choice even though I have read Twain a great deal, beginning in my teens. He always has something pointedly funny to say about the human condition. So it's hard for me not to include him in anything. It's not exactly narrative either. The tough ones are three and four.
Three tries to tell you what it would be like to live in another country. I think it likely is the choice you are looking for.
Answers 1,23. I could be wrong, so if you have a different answer in mind, go with it.
Answer:
a. Craves meat, howls, and becomes increasingly animal-like.
Explanation:
Rudyard Kipling's short story "The Mark of the Beast" tells the story of how a newly arrived landowner from England to India had desecrated the Hindu god Hanuman. His act of branding the image of the god with a cigarette butt with "<em>Mark of the B--beasht</em>" had led to the "Silver Man" to put a curse on him.
After Fleete grind the cigar into the forehead of the temple statue, the naked and leprous man "Silver Man" touched him with his head to Fleete's chest. This started the transformation of Fleete from a civilized Englishman into a beast- his smelling senses grew more refined and he began to crave and eat raw meat. And in a short number of days, he fully leaves behind any form of a human and began howling like a wolf.
Because you should read it again and answer it yourself
