2. 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.

答案是A， 可我觉得是E，

5. Archaeologists have found wheeled ceramic toys

  made by the Toltec, twelfth-century inhabitants of

  what is now Veracruz. Although there is no archaeo-

  logical evidence that the Toltec used wheels for

  anything but toys, some anthropologists hypothesize

  that wheeled utility vehicles were used to carry

  materials needed for the monumental structures the

  Toltec produced.

  Which of the following, if true, would most help the

  anthropologists explain the lack of evidence noted above?

  (A) The Toltec sometimes incorporated into their

      toys representations of utensils or other

      devices that served some practical purpose.

  (B) Any wheeled utility vehicies used by the Toltec

      could have been made entirely of wood, and

      unlike ceramic, wood decays rapidly in the

      humid climate of Veracruz.

  (C) Carvings in monument walls suggest that the

      Toltec’s wheeled ceramic toys sometimes had

      ritual uses in addition to being used by both

      children and adults as decorations and playthings.

  (D) Wheeled utility vehicles were used during the

      twelfth century in many areas of the world,

      but during this time wheeled toys were not

      very common in areas outside Veracruz.

  (E) Some of the wheeled ceramic toys were found

      near the remains of monumental structures.

答案是B， 我认为是C

for question #5:

B is right b/c it indicates that the wheeled ceramic toys  may have been copies of the wood wheeled utility vehicles that those people used to carry object a long time ago. The only problem (as B says) is that now the wood ones have all decayed and are no where to be found.

C is out of scope
