Concept:Arranging conversational exchanges in a logical and coherent sequence to form a meaningful dialogue.Explanation:To create a meaningful conversation, we need to follow a natural flow of interaction. Typically, a greeting is followed by an inquiry about well-being. The response to the inquiry then prompts further questions or comments. Let's trace the given options:1. The conversation starts with a greeting: (c) "Hi George! How have you been?"2. George's response to the greeting: (a) "Not, too well." This indicates something is wrong.3. The friend's reaction to George's state: (d) "How come? What’s the matter?" This is a natural follow-up question.4. George explains the reason for his unhappiness: (b) "I’m beginning to hate my job." This answers "What's the matter?".5. The friend expresses surprise, recalling George's previous feelings: (e) "I thought you quite liked it." This shows a contrast to George's current statement.This sequence (c, a, d, b, e) creates a complete and sensible conversation.Answer:c, a, d, b, e
