A compound sentence joins two or more independent clauses with a coordinator such as and, for, but, or a semi-colon. Independent clauses are made up of two phrases that can stand alone as a complete thought. They are not dependent upon one another, but they put together similar ideas. What is more, they contain three things: a subject, an action, and a complete thought (take 1).
1) I like reading, and I'm buying a new book on Friday
In the sentence above, you can see that the comma is placed after the independent clause (I like reading) and before the coordinating conjunction (and).
It is obvious the first question would be what is the text about,what does the author try to convey and how does he presents the facts to manage his goals.
