A、It is easier to clean and repair. B、It is non-fixed and flexible. C、All its units are of the same height. D、Its chopping board

Terry: Well what have we got this morning? The first thing I think is to complete the voice-over for that cutlery commercial.
Joyce: No... I’ m afraid you are mistaken. Instead of completing that.., em... We’ ye got to come up with a selling idea for those kitchens. Remember? The boss will be wanting to see us after lunch...and he’ll be expecting it all to be more or less tied up... parcel-like.
Terry: Wouldn’t it be better to finish one job before beginning another? The boss will understand surely.
Joyce: Forgive me Terry if I keep correcting you.., but remember there are deadlines. And when there’ s a deadline the boss is as immovable as a barnacle.
Terry: So we’ll have to come up with the parcel. Any ideas?
Joyce: Absolutely none. And my usually grasshopper brain is not at its come-up-with-the-ideas best this morning. Let’ s have a look at the details.
Terry: Well... whatever its like we’ ye got to make it a dream. Gleaming perfection...slick.., everything fitted-fitted is a key word isn’t it-Everything to avoid the impression of the inevitable mess that kitchens actually get in.
Joyce: How clear it is, Mr. Hancock, that you are new to the adman’ s business. I’ m afraid you are on the wrong track. There you are making decisions already... Gatsbying about the office.., thinking already that the key works to this ad are going to be... what... "timeless, sophisticated beauty" ... "the haute couture of haute cuisine" ... and you’ve forgotten the adman’ s first rule.
Terry: Which is?
Joyce: Hard deskwork, getting to know the facts. You’ ve got to knead the dough before you can ice the cake. Mm...Now draw up a pew, will you? And we’ll look at the ingredients.
Terry: What makes this kitchen different from any other?
Joyce: Now that’ s a leading question. Mm...Here are some photos. What do you notice?
Terry: They, re all different.., the photos I mean. In fact it’ s different from all the other kitchens on the market-that they’ re all fixed aren’t they? And this is all.., well...non-fixed.
Joyce: All the various units can be moved about. Now that’ s sensible. Because there are times...
Terry: ... there are times arch’ t there when for example you need the chopping-board near the sink...and other times when you need it near the cooker.., and...
Joyce: So you do know something about kitchens.
Terry: Not kitchens exactly. But. cooking... yes... I do some cooking occasionally.
Joyce: Good for you. The nearest I get to it is jig-sawing tins open and tossing the odd frozen meal into the oven. Perhaps that’ s what most women now want a kitchen for. simple. function. made to accommodate the Mute cuisine of the deep-freezer.
Terry: No... I’ m sure you are wrong. Most practical women of the house want a kitchen to be... er... flexible.., er... like kitchen used to be.
Joyce: Well, there’ s one flexible thing at least about this kitchen. What shall we call it? Mobility of units? Anyway the idea’ s there. So there is one thing different about this kitchen.
Terry: Sorry to...er...to correct you Joyce-but there’ s something else you haven’ t noticed.
Joyce: Oh, yes?
Terry: You say there’ s one difference, but in fact there are two. You see most manufacturers of kitchen units produce all the units of the same height.
Joyce: Lot’ s of working surfaces...yes...but...
Terry: But only one height. It makes production cheapen
Joyce: Well, surely that’ s fine. I mean.., there is an ideal working height.
Terry: I beg to differ. You’ re quite wrong you know. Now what are some of the things you need to do in the kitchen?
Joyce: Unwrap sliced bread.., defreeze the stuff from the freezer.., open tins...
Terry: Have you ever, for example, tried.., er... er... frosting cake mixture at the same working height as... well.., as slicing bread? You see you need those different heights. Otherwise sometimes you’ re up on your toes.., some times down on your knees.
Joyce: So it doesn’t look as if we want a nude-in-an-apron-at-an-eye-level-grill sort of picture. Something practical this time. Something with the idea of... let’ s think of some words...
Terry: Mm... Multi-height. multi-mobile...
Joyce: Yes... and a whole series of tiny pictures showing the multi-purpose character of...
Terry: And the old-type kitchen was multi-purpose...
