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.　（Ｂ）
  (E) Some of the wheeled ceramic toys were found
   near the remains of monumental structures.

这题我选错了．我选Ａ．发现是对问题的理解错了．问题说是：哪个选项可以帮助人类学家解释证据的缺失．是解释为什么没有证据．所以，Ｂ很好的解释了．木头容易腐烂，所以实际交通工具中的轮子都腐烂了．

而我选Ａ，是错误的认为题目是问：哪个可以help人类学家的推测．
