Step-by-step explanation:
The author F. Scott Fitzgerald employed the use of irony and sarcasm in several instances to convey his point of view about society during Gatsby’s time in the story. Note, Irony is a literary device that employs using expressions or actions whose true meanings are actually opposite of what is said or done.
For example, if we could remember from chapter 2 that Myrtle Wilson who is married to a man who isn't affluent, just an auto-mechanic, tries to paint herself as a woman of wealth, saying how it had been difficult to find "suitable help". This is an irony because she doesn't fit such a personality.
