CR-Refrigerators

by gmat009 » Sun Sep 28, 2008 1:28 pm
The reason much refrigerated food spoils is that it ends up out of sight at the back of the shelf. So why not have round shelves that rotate? Because such rotating shelves would have just the same sort of drawback, since things would fall off the shelves’ edges into the rear corners.
Which of the following is presupposed in the argument against introducing rotating shelves?
(A) Refrigerators would not be made so that their interior space is cylindrical.
(B) Refrigerators would not be made to have a window in front for easy viewing of their contents without opening the door.
(C) The problem of spoilage of refrigerated food is not amenable to any solution based on design changes.
(D) Refrigerators are so well designed that there are bound to be drawbacks to any design change.
(E) Rotating shelves would be designed to rotate only while the refrigerator door was open.

claim: refrigerated food spoils bc (a) out of sight (b) back of shelf
alternative: rotate shelves? nope food still rots bc it falls off in the rear corners ie back of shelf and out of sight

The question you need to ask yourself is - How to identify the assumptions and underlying assumptions?

In this you want to focus your attn on the alternative which was rotating shelves and the fact that the argument tells you that it wont work bc stuff falls off of it and into the back. This means that there is something wrong with the actual design of the shelves within the confines of the fridge.

Start with choices that highlight designs of the shelves within the fridge - A and E, and eliminate the rest. B is out bc you dont care about the windows. C is out bc it doesnt narrow design to the shelves themselves and its basically saying that food doesn't respond to design changes - which doesnt make sense. D is out bc it doesnt talk about the shelves. So that leaves E and A. Start with E, what significance does it have to the statement that food still rots bc it falls off in the rear corners ie back of shelf and out of sight? Not sure, move to A. Since A talks about the design and gives you an underlying assumption of the circular design of a rotating shelf and food falling off of it bc of a square box design of the fridge, it is the better answer.

In my opinion A is the most logical one.
