The article identifies a ''tacit racial hierarchy'' in the animated film, Rio 2, which replicates parttens in racial stereotyping throughout movie history. Based on the examples given in the film, discuss what is meant by this and why this invokes the author's criticism?

The article you mean is "Repressed Brits, evil Mexicans, Arab villains: why are Hollywood's animated movies full of racist stereotypes?" in The Guardian.
