[单项选择]
With a new Congress drawing near, Democrats and Republicans are busily designing competing economic stimulus packages. The Republicans are sure to offer tax cuts, the Democrats -- among other things -- financial relief for the states. There is one measure, however, that would provide not only an immediate boost to the economy but also immediate relief to those most in need: a carefully crafted extension of the federal unemployment insurance program.
