The article you mean is "Repressed Brits, evil Mexicans, Arab villains: why are Hollywood's animated movies full of racist stereotypes?" in The Guardian.
One example of the racial stereotyping is that the characters in the movie which are there for comic relief (so not given roles with a "serious" message) are voiced predominantly by black actors, which replicates the pattern of placing black characters in roles of providing amusement, but which are not treated seriously.
Answer: Free verse
Explanation: Free verse doesn't have any specific pattern. They can be any way the poet wants.
An easy example can be Hamlet. Some directors of the play put him in the setting where the ghost is real and played by another actor. Others put him in a setting where the ghost is played by the Hamlet actor giving off the impression that he is insane. These are two different settings for the same character and create completely different images. Use this paragraph as a starting point for your essay.
B. Sketching a setting. It is a stage in which you have to answer questions about the main character. Sometimes you can answer questions about other characters, but take into account that they have to be relevant questions.
