W: Dr Manning, do you have a few minutes? I’d like to ask you about this fossil I found.
M: Sure. What have you got there?
W: Well, it’s some kind of shellfish. I thought it might be a brachiopod, but I am not sure. I found it when I went out hiking last weekend.
M: I think you might be right. It certainly appears to be a brachiopod. But it’s easy to confuse them with the bivalve mollusks. Superficially they resemble one another. Both have two shells for example.
W: How can you tell them apart then?
M: Well, there are some minor differences in the shell. A lot of brachiopods have ridge shells like this one. There are other distinctions of course. Internally they are quite different. Mollusks and brachiopods belong to different animal groups, and they had been in competition with one another millions of years ago.
W: How old do you think this one is?
M: It’s hard to tell. The earliest brachiopods were from the Paleozoic era, 300 to 500 million years ago. They were quite successful then in terms of the number of species. It’s not out of the question that your fossil could be that old.
W: Wow, that’s amazing. It makes paleontology seem more interesting when you can hold it in your hand.
M: You know, that gives me an idea. Would you mind bringing this to our next class? The others might find it interesting too.
W: Well, I could. But if you don’t already have one in your collection, I thought you might as well keep it.
M: That’s very kind of you.

答案
B
解析
[听力原文]
What does the professor say about the age of the fossil?
信息明示题。男士说最早的腕足类动物化石年代为三亿到五亿年,女士的化石的年代也可能那么久远,故选B。 out of the question意为“不可能的”,与question相关的短语还有:bring sth.into question对某事提出疑问;call sth.in/into question对某事物表示怀疑;there is some/no question of...有/没有…的可能性,如:There was some question of selling the business.有可能将公司转让。
