In late 1997, the chambers inside the pyramid of the Pharaoh Menkaure at Giza were closed to visitors for cleaning and repair due to moisture exhaled bv tourists, which raised its humidity to such levels so that salt from the stone was crystallizing and fungus was growing on the walls. (A) due to moisture exhaled by tourists, which raised its humidity to such levels so that salt from the stone was crystallizing (B) due to moisture that tourists had exhaled, thereby raising its humidity to such levels that salt from the stone would crystallize (C) because tourists were exhaling moisture, which had raised the humidity within them to levels such that salt from the stone would crystallize (D) because of moisture that was exhaled by tourists raising the humidity within them to levels so high as to make the salt from the stone crystallize (E) because moisture exhaled by tourists had raised the humidity within them to such levels that salt from the stone was crystallizing 这题OG的解释： 为什么 them 在 D选项 中是指代tourists ，但是在 E选项 中them又是正确地指代了chambers？

请教may老师这道题的思路

老师，逻辑200题这个题，我觉得B是抬扛呀，原文说这个有关系，这个B选项说没关系，这不也是抬扛的一种吗。我选的A，是因为我觉得我当时设想的答案可以就是cliche在这个环境中是没啥作用的，不会影响elect的最终成功与否，这个A选项我觉得就是表达了我这个意思

老师，这是逻辑200题里面的，您在视频课里讲到的一点，这个less cooperative得有比较，也就是看钱和不看钱的得有比较，原文只有看钱的，没说不看钱的，我非常同意，我当时也是这么想的，所以选择了C

例题9， 间接法-4C1* 6C1 是指4对夫妻中的一对，是二个人. 6C1指6人中的1人， 一对夫妻* 1人，单位数量不对，可以相乘？

例17，如何知道剩下6人不符合电脑系，剩下8人不符合数学系？如何知道是哪些人不符合2个部门？假如题目写if none of the rest of candidates 会表意精确些？

例16， 假如数字变大，选出50本，不可能手算的，我的解题思路看右边， 4C1*6C1* 8C3， 为什么不能这么算？

例题16, 因为要求value of K. 1) 怎么变成条件到结论的推导, sufficient or insufficient? 2) 单看条件2，7平方不是K因子. 怎么会条件2成立？ 因为有6 factors.

例题17 好不清楚的点是 2n= a*b*c*d, 1)为什么要假设质因数(prime factor)里面是否有2.因为本来就是2n，而且条件1提到4个不同的质因数. 2)题目是求确切值？还是说sufficient or insufficient ? 问how many

请问这道题该怎么判断

请问这道题D选项和E选项应该怎么判断？
