Man: Hey, Jane! What’s so interesting?
Woman: What? Oh hi, Tom. I’m reading this fascinating article on the societies of the Ice Age during the Pleistocene period.
Man: The Ice Age? There weren’t any societies then – there were just small groups of people living in caves, right?
Woman: That’s what people used to think. But a new exhibit at the American Museum of Natural History shows that Ice Age people were surprisingly advanced.
Man: oh, really? In what ways?
Woman: Well, Ice Age people were the inventors of language, art, and music as we know it. And they didn’t live in caves; they built their own shelters.
Man: What did they use to build them? The cold weather would have killed off most of the trees, so they couldn’t have used wood.
Woman: In some of the warmer climates they did build houses of wood. In other places they used animal bones and skins or lived in natural stone shelters.
Man: How did they stay warm? Animal-skin walls don’t sound very sturdy.
Woman: Well, it says here that in the early Ice Age they often faced their homes toward the south to take advantage of the sun – a primitive sort of solar heating.
Man: Hey, that’s pretty smart.
Woman: Then people in the late Ice Age even insulated their homes by putting heated cobblestones on the floor.
Man: I guess I spoke too soon. Can I read that magazine article after you’re done? I think I’m gonna try to impress my anthropology teacher with my amazing knowledge of Ice Age civilization.
Woman: What a show-off!
31. Narrator: What did the man think about people of the ice Age?
32. Narrator: What does the woman say about the use of wood during the Ice Age?
33. Narrator: How did people in the early Ice Age keep warm?
34. Narrator: What does the man want the woman to do?
Man: I really appreciate your filling me in on yesterday’s lecture.
Woman: No problem, I thought you might want to go over it together. And, anyway, it helps me review. Hope you’re feeling better now.
Man: I am. Thanks. So, you said she talked about squid? Sounds a little strange.
Woman: Well, actually, it was about the evolution of sea life – a continuation from last week. The octopus and the squid descended from earlier creatures with shells. They survived by shedding their shells – somewhere between 200 and 500 million years ago.
Man: That’s a pretty long span of time.
Woman: I know. That’s what she said, though. To be precise: “Exactly when they emerged is uncertain, and why is still unexplained.”
Man: Some squid are really huge. Can you imagine something that big if it still had a shell?
Woman: Actually, it’s because they lost their shells that they could evolve to a bigger size.
Man: Makes sense. I’ve read about fishermen who caught squid that weighed over a ton. Did she talk about how that happens?
Woman: Not really. But she did mention some unusual cases. In 1933 in New Zealand, they caught a giant squid … let’s see here …. it was 20 meters long. Its eyes were almost 46 centimeters across. Can you imagine?
Man: Reminds me of all those stories of sea monsters.
Woman: Professor Simpson thinks there are probably even larger ones that haven’t been found because squid are intelligent and fast – so they can easily get away from humans. Maybe some of those monster stories are true.
35. Narrator: What topic are the man and woman discussing?
