Why does the woman tell the man the story? [br]
W: I see you are having the fish for lunch.
M: That’s right. Fish sticks and tomato soup, my favorites.
W: I bet they were frozen.
M: What?
W: The fish sticks.
M: Of course they were frozen. We are hundreds of miles from the ocean. The cafeteria can’t afford to fly in fresh fish.
W: I just mentioned it because an anecdote Professor Chambers told me in my American social history class this morning.
M: He talked about fish sticks?
W: Not exactly. But he did talk about frozen fish. OK, this is back in 1912, right? It’s 20 degrees below zero. And this guy Clarence Birdseye’s out ice-fishing.
M: Where is this, Antarctica?
W: No. Massachusetts I think. Anyway he catches a fish and drops it beside him on the ice and it freezes solid.
M: So?
W: So, (3)later at home he thaws out the fish in a bucket of water and it’s alive. Of course Birdseye is amazed. But he eventually figures out that the fish froze so fast that no large ice crystals formed.
M: What do you mean?
W:(2)Look, usually when a plant or animal cell freezes, large ice crystals form inside and eventually tear the cell walls. That’s what kills the frozen plant or animal. And also what changes the taste of something that’s been frozen. But if you freeze something quickly, only very small ice crystals form. So Birdseye invented the process of quick freezing food.
M: And that was the beginning of frozen foods?
W: Right.
