Условие.

47 Read the rest of Jeff and Monica's conversation from Ex. 44.

Complete the sentence with the most appropriate option (a–c).

Jeff explains ...

a) what a smart house is.

b) how to build a smart house.

c) how to produce clean energy.

Monica: The project is called Smart House, you said. What is it about?

Jeff: Remember that it wasn't me who started talking about it. I can go on about it for hours.

Monica: OK, let's sit down then.

Jeff: Right. Well ... The idea of a smart house supposes that people living in it have all the possible comfort you can imagine. Also the house is self-independent in terms of energy supply and eco-friendly. The last point is very important. As the house is stuffed with household electronic devices, they should use as little electricity as possible.

Monica: Yes. That's clear.

Jeff: The amount of the energy they consume for heating and cooling, lighting, cooking, vacuum cleaning and washing is electronically controlled.

Monica: That's done to minimize the amount of energy we use, isn't it? The system switches on the devices we need and switches off the devices we don't need at any moment.

Jeff: Exactly. And another feature of a truly smart house is that it uses only 'clean energy'.

Monica: 'Clean energy'? That's the energy of the sun, wind, and water?

Jeff: Right. To produce clean energy we use renewable resources and do not pollute the environment. You know that using gas and oil for domestic needs is old-fashioned. It's a dead end. Only clean technologies should be used in the future.

Monica: Do you think it's possible?

Jeff: I'm sure it is. And there are special engineering and technological solutions to do it.

Monica: OK. Fine. And you also say a smart house should provide lots of comfort, don't you?

Jeff: Yes. A smart house supposes that all the devices communicate with each other. They are put in a network and they are all at your command. You can give a command with your voice, or your smart phone, or tablet, and the system decides by itself how to do the job in the most efficient and economical way. It switches on the devices needed for this and decides in what order they should be switched on.

Monica: Sorry, I can't say I understand. Could you give a practical example?

Jeff: Yes, sure. For example, you give the command "I want the perfect start to my day."

The system understands that it means the following: you want to have your bath filled with water of a certain temperature, you want your breakfast cooked and kept comfortably warm for eating, you want your favourite TV or radio channel to entertain you during your meal.

You can also be informed about the weather forecast, the latest news, the traffic jams, whatever, according to your interests.

Monica: Are you saying a single voice command is enough for all this?

Jeff: Yes.

Monica: Sounds fantastic! But what if... ?

Jeff: What if something goes wrong and the electricity goes out? An accident, a natural disaster, or they just run out of oil?

Monica: Yes. Does this mean the whole system collapses and the house becomes useless?

Jeff: To avoid this situation a smart house should have independent energy supplies — it should have devices that can produce and store energy.

Monica: Look, Jeff, it's very interesting and I would like to learn more about it, but...

Jeff: But not now, right?

Monica: Yes, the thing is...

Jeff: It's fine, Monica. I need to be off too. We'll continue the conversation when we both have time.

Monica: Fine. See you later, then.

Jeff: See you!
