单选题 The school shooting triggered a barrage of transparently irrelevant proposed solutions, tossed out without regard to their relevance to the events that supposedly ______ the proposals.
【正确答案】 A
【答案解析】[解析] occasion意为“引起，惹起”，concern意为“涉及，关心到”，illuminate意为“阐明，说明”，ensue意为“跟着发生，追求”。根据题意，与proposal构成合理搭配的词是occasion，即“引起议案”。句中a barrage of意为“大量的，接二连三的”。正确答案为A。
