## Why these answers are right

**21. C.** The question asks what entrants must do. John says saving energy was last year's focus, and this year they must take an innovative approach to existing technology, using it in a way not thought of before. That matches C, a new use for current technology.

**22. A.** John explains why he picked the dishwasher. He says most are pretty boring and almost identical, and some people will pay a little extra for one that looks different. Wanting a machine that looks better than the dull ones points to A, more appealing.

**23. B.** The professor asks whether the stone is just for decoration. John says it does have a function: instead of pushing a button, you turn the stone, and the professor sums this up as a novel way of starting the dishwasher, which is B.

## Transcript

**Announcer:** Section 3.

**Announcer:** You will hear a student called John talking to a professor about a design competition he is entering.

**Announcer:** First, you have some time to look at questions 21 to 25.

**Announcer:** Now listen carefully and answer questions 21 to 25.

**John:** Um, hello, professor.

**John:** I'm John Wishart.

**John:** I'm working on my entry for the global design competition.

**John:** My tutor said you might be able to help me with it.

**Professor:** Oh, yes.

**Professor:** I got a copy of your drawings.

**Professor:** Uh. Come in and tell me about it.

**Professor:** What sort of competition is it?

**John:** Well, it's an international design competition, and we have to come up with a new design for a typical domestic kitchen appliance.

**Professor:** I see.

**Professor:** And are there any special conditions? Does it have to save energy for example?

**John:** Actually that was the focus in last year's competition.

**John:** This year is different, we have to adopt an innovative approach to existing technology, using it in a way that hasn't been thought of before.

**Professor:** I see, that sounds tricky.

**Professor:** And what kitchen appliance have you chosen?

**John:** Well, I decided to choose the dishwasher.

**Professor:** Interesting.

**Professor:** What made you choose that?

**John:** Well, they're an everyday kitchen appliance in most Australian houses, but they're all pretty boring, and almost identical to each other.

**John:** I think some people will be prepared to pay a little extra for something that looks different.

**Professor:** It's a nice idea.

**Professor:** I see you've called your design 'The Rockpool'.

**Professor:** Hmm. Why is that?

**John:** Basically because it looks like the rock pools you find on a beach.

**John:** The top is made of glass, so that you can look down into it.

**Professor:** And there's a stone at the bottom.

**Professor:** Is that just for decoration?

**John:** Actually it does have a function. Instead of pushing a button, you turn the stone.

**Professor:** So it's really just a novel way of starting the dishwasher.

**John:** That's right.

**Professor:** It's a really nice design, but what makes it innovative?

**John:** Well, I decided to make a dishwasher that uses carbon dioxide.

**Professor:** In place of water and detergent?

**Professor:** How will you manage that?

**John:** The idea is to pressurize the carbon dioxide so that it becomes a liquid.

**John:** The fluid is then released into the dishwasher where it cleans the dishes all by itself.

**Professor:** Sounds like a brilliant idea.

**Professor:** Your system will totally do away with the need for strong detergents.

**Professor:** So what happens once the dishes are clean?

**John:** Well, uh, to allow them to dry, the liquid carbon dioxide and the waste materials all go to an area called the holding chamber.

**John:** That's where the liquid is depressurized, and so it reverts to a gas.

**John:** Then the oil and grease are separated out and sent to the waste system.

**Professor:** It sounds like you've thought it all out very thoroughly.

**Professor:** So what happens to the carbon dioxide once the process is complete?

**Professor:** Not wasted, I hope.

**John:** Actually, that's where the real savings are made.

**John:** The carbon dioxide is sent back to the cylinder, and can be used again and again.

**Professor:** What a terrific idea.

**Professor:** Do you think it will ever be built?

**John:** Hmm. Probably not, but that's OK.

**Professor:** Well, I'm sure a lot of positive things will come out of your design.

**Announcer:** Before you hear the rest of the discussion, you have some time to look at questions 26 to 30.

**Announcer:** Now listen and answer questions 26 to 30.

**Professor:** Now you seem to have thought about everything, so what exactly did you need me to help you with?

**John:** Well, my design has made it to the final stage of the competition, and in a few months' time, I have to give a presentation.

**John:** And that's the part I was hoping you could help me with.

**Professor:** Right, well that should be easy enough.

**Professor:** What have you managed to do so far?

**John:** Well, I've got detailed drawings to show how it will work, and I've also written a 500-word paper on it.

**Professor:** I see.

**Professor:** Well, if you want to stand a good chance of winning, you really need a model of the machine.

**John:** Yes, I thought I might, but I'm having a few problems.

**Professor:** What's the main difficulty so far?

**Professor:** Let me guess, is it the materials?

**John:** Yes, I want it to look professional, but everything that's top quality is also very expensive.

**Professor:** Look, projects like this are very important to us.

**Professor:** They really help lift our profile.

**Professor:** So why don't you talk to the university about a grant?

**Professor:** Oh, I can help you fill out the application forms if you like.

**John:** Oh, that would be great.

**Professor:** You'd better show me this paper you've written as well, for a global competition such as this.

**Professor:** You need to make sure the technical details you've given are accurate and thorough.

**John:** Oh, that would be a great help.

**Professor:** Is there anything else I can do?

**John:** Well, I'm really...

**Announcer:** That is the end of section 3.

**Announcer:** You now have half a minute to check your answers.
