听力原文：W: Hi, Bill, how is it going？
M: Oh, hi, Jane. I'm OK. How about you？
W: You can probably tell just by looking at me. I'm really busy. Hey, What are you reading？
M: A pretty interesting article. My biology professor assigned it, and I thought I would just look it over. But I got really involved in it. It's about endangered species.
W: That sounds pretty interesting. I'm getting frustrated with the two research papers I'm struggling with.
M: Oh？
W: And can you believe they are both due on the same day？
M: That's tough.
W: I'll get through it. So what's this you are reading？
M: Well, it's basically about the choices conservationists are faced with. You know, these days when funding is so hard to come by.
W: Wait a minute. Does it focus on biology or economics？
M: Both. Conservationists don't have enough funding to save every endangered species in the world, so they have to decide based on what would be lost if a species became extinct.
W: Can you give me an example of what you mean？
M: Take for instance, two animals, the spotted owl and the tailed toad. The article says the toad is unique. It has no relatives. But there are a lot of varieties of owls.
W: So, if that toad became extinct, we'd lose an important link in the chain of evolution, right？
M: Exactly. But that isn't so for the owl. So for conservationists, it might be a clear choice which animal to save.
W: I see. I am glad I don't have to make that kind of decision. Aren't you？
