Homeostasis-when your body try's to maintain stability (stable condition)
To understand an author's purpose for writing, a reader must consider (you can choose more than one option if you think they apply):
1. The name of the text. The title of their work usually give us an idea of what is the author focusing on. The choice of words is a very important decision.
2. The author's use of language. With this, the reader can understand which is the author's believe about the subject and what he or she is trying to tell us.
3. The author's approach to discussing the topic. He or she will probably focus in some determined aspect of the topic, and this will tell much about his or her purpose for writing the piece.
