Liz: Hi Mum. Mother: Hello darling, how are you? Liz: Fine thanks, and you? Mother: Oh, really well thanks. How is your class selection going? Liz: Fine. I met with my school counselor, and he showed me which classes I have to complete by the end of the year, and which ones I can choose as electives. Mother: Anything interesting? (1)Liz: Well, yes. Even though I'm in a psychology program, I can still take an elective or two. (2)History of art really appeals to me; it might even help with my major. Mother: Yes, it'll help you understand how thoughts and attitudes have developed in society. It'll also give you a break from so much heavy thinking! I would certainly do it. You'll probably learn a lot more from it than you realize. Liz: Yes, that's how I feel about it too. I still have a week to make my final choices. I'll let you know once I've made them.  1a.
