Conversation A
Greg sees his sister, Maggie, reading.
Greg: What are you reading? Do you have your nose in a science fiction book again?
Maggie: Actually, I’m reading a magazine that’s talking about life on Mars.
Greg: I know that’s a popular theme for science fiction movies, but people can’t really live there, can they?
Maggie: Not yet. But humans might be able to live there someday.
Conversation BGreg: People are preparing for the end of the world, huh? So how could people possibly live on Mars? Isn’t it really cold there?
Maggie: Yeah, it’s cold. But it’s the planet with a climate closest to Earth’s. We’d have to change some things before people could live there.
Greg: Like what?
Maggie: We’d have to make Mars warmer. That would also melt5 the ice there, so we could drink the water.
