Hello. You have not informed the type of letter or the subject that the letter will deal with. This makes it impossible for me to answer your question. However, to help you out I'm going to tell you the types of structures you can use in your letter. Hope this is helpful for you.
First, it is important that you know that structure is how the information in your letter will be presented. This structure can be of the Chronological type, if in the letter, you are talking about an order of events that happened in a sequence of different dates or times. The structure can also be of the Comparison/Contrast type, if the letter is shown the similarities and differences between elements. The letter may also present the Problem-Solution structure, if it is showing how certain problems and ways to solve them, or how those problems are solved.
In addition, the card may have the structure called Cause and Effect, which occurs when the letter features certain elements that exist because they were caused by other elements. Finally, the letter can have a structure called Descriptive, which occurs when the letter is describing something or someone.
Answer:
In a flashback, Dana describes the first time she met Kevin, at which time she was working various low-wage jobs during the day and writing her novel at night. The irony of referring to these jobs as a "slave market" is both verbal and situational. Verbal irony is when words are used to convey the opposite of the literal meaning. Dana and her coworkers refer to their jobs as a "slave market" to express their discontent with the physical nature of the work and the low wages. However, the fact that they are paid for their work supports the opposite fact—this is far from slavery. Even Dana says, "Actually, it was just the opposite of slavery. The people who ran it couldn't have cared less whether or not you showed up to do the work they offered." Situational irony is when there is a disconnect between what a person expects to happen and what actually does happen. The situational irony is that Dana, a free, modern black woman, expects to remain as such. When she is cast back in time and forced to survive real slavery, she witnesses the slave market in its full meaning.
