(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？
