The 151memeber governments of the World Bank are expected to increase the bank's funding by $175billion, though some United States legislators cite an obstacle to congressional passage being the concern that the bank's loans will help foreign producers compete with American business.

请问下E这个选项具体的错误在哪呢

the problem with (e) is "it". it's not ambiguous, though; it actually doesn't refer to anything at all. there's no noun in there, anywhere, to which "it" can refer.

("Ambiguous", in reference to pronouns, is used to refer to a pronoun that has 2 or more possible antecedents, not to refer to a noun that has no possible antecedent.)
