In all arguments, there will be certain ideas taken for granted by writer. typically, these ideas will not be staterd. you will have to find them by reading between the lines. these ideas are important invisible links in the reasoning structure, the glue that holds the entire argument together. until you supply these links, you cannot truly understand the argument
