Can someone help me understand this theatre essay question a little better?

Question

"Discuss the characterisation of the two couples in Ken Duncum's 'Cherish' and how each character contributes to your interpretation of the meaning of the play. Relate your discussion to the course theme of cultural encounters.

*Cherish is the name of the play we have been reading.
I basically want to understand the characterisation part a little clearer and any ideas on how to approach this one are welcome. Its an essay for a second year Bachelor of Arts Theatre paper. Thanks!

Answer 1

Compare and contrast the two couples, their personalities, interaction between the couples, and how their characteristic traits relate to the theme of the play.
