We must agree to disagree! "I beg to differ" and "I disagree" express disagreement.

You need to have in mind these 6 keys to succeed:

1. The writer in his time: social novel/social realism
2. Commitment and resistance
3. Transgression, derision, humor
4. Censoring and censored art
5. Rhetorical skills in famous speeches/debates
6. Political debates (including war literature)

The right answer is: The Enormous Radio by John Cheever and Ken Loach’s movies. But Daniel Defoe’s Moll Flanders and William Hogarth’s paintings and engravings can also exemplify social realism.

The right answer is: The Animal Farm by George Orwell and Elvis Presley’s music. But we can also think of The Loneliness of the Long-distance Runner by Alan Sillitoe or Things Fall Apart by Chichua Achebe.

The right answer is: The Great Dictator by Charlie Chaplin and Waiting for Godot by Samuel Beckett. Mr Bean and the Cohen Brothers’ movies also tackle transgression, derision and humor.

The right answer is: Lady Chatterley’s Lover by D.H. Lawrence and The Catcher in the Rye by J.D. Salinger. But we can also think of "banned books" and "trigger warnings" (exhibitions) and The Picture of Dorian Gray (preface) by Oscar Wilde.

The right answer is: Yes we can by Barack Obama and The Great Debaters by Denzel Washington. But Nelson Mandela’s I am prepared to die and George Cukor’s My Fair Lady can also exemplify rhetorical skills in famous speeches/debates.

The right answer is: Preservation by Raymond Carver and The Sniper by Liam O’Flaherty. We can also mention The Tenth Man by Graham Green.
