110. It has been estimated that the annual cost to the United States of illiteracy in lost industrial output and tax revenues is at least $20 billion a year.
(A) the annual cost to the United States of illiteracy in lost industrial output and tax revenues is at least $20 billion a year
(B) the annual cost of illiteracy to the United States is at least $20 billion a year because of lost industrial output and tax revenues
(C) illiteracy costs the United States at least $20 billion a year in lost industrial output and tax revenues
(D) $20 billion a year in lost industrial output and tax revenues is the annual cost to the United States of illiteracy
(E)lost industrial output and tax revenues cost the United States at least $20 billion a year because of illiteracyIn choices A, B, and D, the combined use of annual and a year is redundant.Choices A, D, and E are awkward and confused because other constructions intrude within the phrase cost... of illiteracy: for greatest clarity, cost should be followed immediately by a phrase (e.g., of illiteracy ) that identifies the nature of the cost. Choice E is particularly garbled in reversing cause and effect, saying that it is lost output and revenues rather than illiteracy that costs the United States over $20 billion a year. Choice B is wordy and awkward, and idiom requires in rather than because of to introduce a phrase identifying the constituents of the $20 billion loss. Concise, logically worded, and idiomatic, choice C is best.
这题的B答案，如果没有前面的annual是不是就对了？
