12. Rising inventories, when unaccompanied correspondingly by increases in sales, can lead to production cutbacks that would hamper economic growth. (A) when unaccompanied correspondingly by increases in sales, can lead (B) when not accompanied by corresponding increases in sales, possibly leads (C) when they were unaccompanied by corresponding sales increases, can lead (D) if not accompanied by correspondingly increased sales, possibly leads (E) if not accompanied by corresponding increases in sales, can lead
A Unaccompanied correspondingly is awkward and ambiguous. B Plural subject inventories does not agree with the singular verb leads. C Wrong tense: past tense were indicates a completed event, but can lead indicates a possibility that continues. D Correspondingly increased sales is awkward and unclear; verb (leads) does not agree with the subject (inventories). E Correct. Not accompanied emphasizes the negative and is preferable to unaccompanied in this usage; corresponding modifi es increases in sales; the modifi er is clear and comprehensible, and there is no subject-verb agreement problem. Th e correct answer is E.
