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 by 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 Agreement; Parallelism Th e plural subject chambers requires plural pronouns. Th e sentence explains a causal sequence: visitors’ breath introduced moisture that caused salt to crystallize, which caused the chambers to be closed for cleaning and repair. Th e phrase due to makes this causal sequence somewhat ambiguous, seeming to suggest that the repairs were due to humidity from visitors’ breath. A Due to is an imprecise expression of the causal connection between the tourists’ breath and the closing of the museum for cleaning; the singular pronoun its does not agree with the plural antecedent chambers. B It is not at all clear what the reference is for the pronoun its; fungus was growing should be parallel to salt … was crystallizing (not would crystallize) because it is another eff ect of the humidity. C Th e pronoun them seems to refer to tourists, which is nonsensical; the entire construction is awkward and wordy; would crystallize is not parallel to was growing. D Once again, them seems to refer to tourists; the entire construction is awkward, wordy, and ambiguous; crystallize is not parallel to was growing. E Correct. Th e causal sequence is clear, and them clearly refers to chambers. Th e correct answer is E.
问题1.听说due to 只能做表语，也就是说只能跟在BE后，否则错。本题AB都是DUE TO 可以这样就排除吗？为什么OG没有说这一点呢？
问题2.原句中，WHICH能修饰到moisture吗？，也就是说能不能跳过exhauled by tourists.
问题3.为什么B项中GMAC老头说its指代不清呢？怎么不清了？“ It is not at all clear what the reference is for the pronoun its”
