Howard is probably ______. [originaltext]Lisa: Hi, Howard. What are you working

Lisa: Hi, Howard. What are you working on?
Howard: Hi, Lisa. (5[D]) I’ve just finished a piece of background music.
Lisa: Background music? Oh, like the music they’re playing here now.
Howard: Yes. You hear it everywhere — in restaurants, airports, supermarkets...
Lisa: In banks too. I noticed it while at the bank today.
Howard: You’re not supposed to notice it. (8[D]) It’s just in the background. It’ supposed to put you in the right mood.
Lisa: I’m not sure I like that idea.
Howard: Well, it seems to work. Companies pay millions of dollars every year for background music. (6[A])Wssupposed to give you a better feeling about yourself and the people around you. Factories use it a lot.It makes the workers happy, and they work better that way. In one factory, music increased roduction 4.5 percent.
Lisa: Now that I think about it, I can’t remember when there wasn’t background music in restaurants and stores.
Howard: Yeah, I know that hamburger places play fast music. When they started playing faster music, they found that a customer spent only seventeen minutes eating. The time was twenty-two minutes before that.
Lisa: (7[C]) So they have more people coming in and out to buy hamburgers.
Howard: Exactly. And that’s good for business. You can see why music has become so popular. In Los Angeles, for instance, thirty different companies are selling background music services.
Lisa: I still think there’s something about it that I don’t quite like.
Howard: I know what you mean, but lots of people would not agree with you.
