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. 我选A，答案为B，不明白。
这道题最初我也选A但仔细分析后觉得应选B. 关键是对所问问题的理解。Which of the following, if true, would most help the anthropologists explain the lack of evidence noted above? 下面的选项，如果正确，将能帮助人类学家解释上述证据的缺乏？（注意不是问used wheels for anything but toys现象解释，也不是support or strengthen，而是问为什么证据的缺乏，请给出一种解释） B的答案， 任何被Toltec使用的轮状的交通工具完全可以用木头制造，并且不像陶瓷，木头在Veracruz潮湿的气候下毁坏更快。（因为腐烂了，所以没有证据） A可解释为什么wheeled ceramic toys made by the Toltec 这一现象。 指教。
个人观点：A的错误在于：representations of utensils or other devices that served some practical purpose里面的东东，未必就一定包括wheeled utility vehicles，如该选项改为The Toltec sometimes incorporated into their toys representations of wheeled utility vehicles that served some practical purpose.应该为正确答案！供讨论！
