What did Klara originally want to do her project on? What did Klara’s friend suggest including information on?

Professor: Good morning, Klara. Take a seat. Right, I’ve read your first draft of your project on housing. Well done.
Klara: Thank you. I know it’s only a first draft though, so I’m sure
     you have some suggestions on how it can be improved. I was
     very nervous at first, because it wasn’t my first choice of topic.
     I had wanted to do something on voting patterns, but getting           Q21
     information ... well, it didn’t look possible within the timeframe.
Professor: Don’t worry. I think that you have made a good choice. Yes,
         a comparison of the factors influencing housing prices. Very
         topical!
Klara: Definitely! There seems to be something about housing prices in            Q22
     the newspapers every day. I just wanted to compare the different
     factors—you know, location, the proximity of facilities such as
     schools ...                                                      Q23
Professor: As I said, a good choice of topic. Now, the first part is very welldone. You clearly introduce what you are going to look at, why and how.
Klara: Do you think that I have covered enough points there?
Professor: I think so. Did you have anything else in mind—you know, something else you’d like to cover?
Klara: Well, a friend suggested that I might include crime rates.             Q24
Professor: Actually, that’s a very good idea. You might consider it. It is
         something that many people take into account  consciously or
         otherwise, when choosing a place to live. Nowadays, the police
         are required to keep quite detailed statistics on crime and you can      Q25
         get them fairly easily. I mean, it’s easy enough to ask for them,
         but it might take a while for the police to get them to you.
Klara: OK. I’ll make a note of that—contact police for crime statistics.
Professor: Now, I have to say that I found the middle part more difficult to
         get through.
Klara: Oh! I thought I had done that rather well.
Professor: Don’t worry—it’s not awful. It’s just that ... well, try to take a
         uniform approach. Use one for each criteria people use when        Q26
         choosing housing. That way, you’re comparing like with like,
         rather than different things.
Klara: Ah, I see. So, I should stick with one as far as possible. Yes, that does seem logical. So, I don’t really need to get more data or write much more? Instead, I need to change ... I’ve got it.
Professor: It just makes it a lot easier to read—that’s the main thing.
Klara: Yes, of course. How about the conclusion?
Professor: Based on the information you’ve provided, I think that you’ve done very well. You’ll have to see if the new information you include changes your conclusion at all. It probably won’t make a big difference, but you might see variations in some areas.
Klara: OK. Do you think that I used appropriate headings? And is the bibliography OK? I know that a lot of professors look long and hard at that, whilst most students think it unimportant.
Professor: Yes, professors find the bibliography very useful—it tells us
         where you are getting your information from and whether those
         sources are appropriate. Your bibliography is fine, but you might
         consider changing the format. Here’s a printout of the most      Q27
         widely accepted format. You can keep that.
Klara: Thank you. And the headings?
Professor: I made a few notes. Here are some suggestions. Don’t feel that
          you have to use them—I won’t be offended! But some of your
         headings are long-winded whereas others are relatively short—as        Q28
         they should be.
Klara: Thank you. I’ll take a look at these later.
Professor: How long did you work on the whole thing?
Klara: Well, two months. Perhaps an average of three hours a day—not more than that. Probably, oh, 150 hours.
Professor: That’s about what I would recommend. Anything less than 120
         hours is going to be detrimental to the project. You’ll probably
         need another 50 hours work on it in total, you’ve still got a             Q29
         month, so you should manage it easily.
Klara: Yes, a couple of hours a day. Easy!
Professor: I’d suggest that you come back to see me in ... oh, about, let’s
       say, three weeks time? Then you should be virtually finished and
       I can have another look before you do your final proofreading
       before handing it in.                                       Q30
Klara: OK. I’ll see you after one of the seminars to make an appointment. Is that OK?
Professor: Certainly. Thanks, Klara.
Klara:    Thank you, professor.
