In this section you will hear ONE interview. The interview will be divided into TWO parts. At the end of each part, five questions will be asked about what was said. Both the interview and the questions will be spoken ONCE ONLY. After each question there will be a ten-second pause. During the pause, you should read the four choices of A, B, C and D, and mark the best answer to each question on ANSWER SHEET TWO.
    You have THIRTY seconds to preview the questions.
     (a thirty-second interval)
    Now listen to Part One of the interview.
A: Not everything about Halloween has to be dark and scary, it can also be green and eco-friendly. Here with some great ideas is Danny Seo, living-green contributor for "Better Homes and Gardens". Hello, Danny! Happy Halloween to you!
B: Same to you.
A: Let’s start with your solar power ghosts.
B: Yeah, can we all have solar lights? And so they are as super energy efficient because they use the power less on the charge-up. So why not just take an old bed sheet? Look what I’m gonna do. You hang it over the solar light, you take a little sharpie, draw on the face of ghost, look, you’ve got an illuminated ghost. So at night, when the sun goes down and solar lights turn on you’ve got these glowing ghosts hanging in the trees.
A: Look at that. Isn’t it beautiful? That’s how it looks like, that’s pretty awesome.
B: And kind of spooky and it uses the power of super energy efficient lights in a very creative way.
A: Can’t beat that. OK, let’s talk about those little ghost lights. These are LED, right?
B: Yes, this is the newest thing in the string right now. LED stands for "light emitting diode". So basically these lights they’re like regular string lights, these are pumpkins. Here is a scary bat. They are gonna last 25, 000 hours if you plug them in.
A: What?
B: So if you do the math like 25,000 ...
A: There must be many Halloweens.
B: Yeah, three and a half years they will stay illuminated. If you plug them in today, three and a half years from now, you have to unplug them because they will finally burn out.
A: That is wonderful.
B: At $9.99, you can’t beat that.
A: I was just gonna say " how did they compare to regular lights?"
B: Yeah, so for the long term it’s great and also if you can feel them, very safe, because they don’t get hot to touch.
