Question

[SCENE-A steamer's life raft rising and falling slowly on the long ground swell of a glassy tropic sea. The sky above is pitilessly clear, of a steel-blue color merginginto black shadow on the horizon's rim. The sun glares down from straight overhead like a great angry eye... The heat is terrific. Writhing, fantastic heat waves risefrom the white deck of the raft. Here and there on the still surface of the sea the fins of sharks may be seen slowly cutting the surface of the water in lazy circles. Two men and a woman are onthe raft. What kind of exposition does the playwright use in this instance?
