核战争将导致漫长的“核冬季”包围地球，这种预测是不可相信的。大气科学家和天气专家无法可靠而准确地预测明天的天气。而核爆炸对本地和世界范围大气情况的影响一定遵循那些控制着日常天气变化的规律。如果天气无法用目前知识预测，那么“核冬季”这一假设用目前的知识也不能预测。
下面哪个，如果正确，将严重削弱上述论断：如果科学家无法准确地预测日常天气，他们对“核冬季”的预测也不可相信

A．核冬季的理论使用的是那些预报日常天气的人可以得到的数据。
B．科学家对核冬季的预测只能是凭空构想的，因为这些预测无法通过不造成伤害的实验加以证实。
C．气象预报人员通常不坚持说他们的预报不会出错。
D．对灾难性自然事件，如火山爆发、地震所做的科学预测比日常天气预报的可信度要低。
E．核冬季这一理论与剧烈的天气变化而非日常天气变化相关。

Archaeologists have found wheeled ceramic toys made by the Toltec, twelfth-century inhabitants of what is now Veracruz. Although there is no archaeological 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 vehicles 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．(E) Some of the wheeled ceramic toys were found near the remains of monumental structures.
