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？

原文我读到：不诚实就难达成政治compromise，结论是不诚实可以说明运作良好。 最后我剩下了A和C两个选项，A的意思是“达成Compromise不一定说明运作良好”；C的意思是“选民有其他判断标准”。 当时我的反应是“C中说到选民，跟原文意思关系较近”。 想听听老师的解题思路，以及我思路的问题。 谢谢老师。
