参考答案

正确答案：B
50.B【精析】该题为推理题。根据第二段第二句和第三句“PresidentBushfailedtoshowanyleadershiponthismatterduringtheNovem-berCongress.Later,hefinallyaskedCongresstoextendtheprogramfortheseworkersandtomakethebenefitseffectivefromDec.28.”可以推断出，布什总统关于失业保险金延期项目的请求滞后了；根据第三段第三句和第四句“UnderMr.Bush'sscheme，federalbenefitswouldbeextendedonlyforthosewhowerealreadyreceiv-ingthemonDec.28.Theextensionwouldnotcoverthejoblessworkerswhowillexhausttheirregularstate-fundedbenefitsafterDec．28…”可以推断出布什总统的计划不全面。综合这两方面的分析，只有B项符合文意。
