[单项选择]As summer rolls around, lawmakers in Washington are preparing to vote on a jobs bill that would include $1 billion for summer jobs for teens. Much of the urgency for the program stems from the private-sector plunge in summer jobs for teenagers over the past few years. It’s no secret that the recession walloped teens’ jobs as much as it did their parents. But some economists find the clamor for public jobs programs a little ironic, given last year’s midrecession minimum wage increase, which may have reduced teen employment even beyond the recessionary drop.
Before the minimum wage jumped to $ 7.25 an hour last summer, University of California-Irvine economist David Neumark estimated that it would lead to an additional 300 000 job losses for teens and young adults. The 2009 wage increase was set in motion in a better labor market in May 2007, when Congress voted to boost the minimum from $ 5.15 an hour to $ 7.25 an hour over the course of the next two years.
It’s hard to pa

B. Washington votes on a jobs bill for increasing teenagers’ summer jobs.
C. The increase in teen unemployment rates is attributed to the combination of the recession and other factors.
D. Raising the wage floor contributed to the high teen unemployment rates.

[单项选择]A recent history of the Chicago meat-packing industry and its workers examines how the industry grew from its appearance in the 1830’s through the early 1890’s. Meat-packers, the author argues, had good wages, working conditions, and prospects for advancement within the packinghouses, and did not cooperate with labor agitators since labor relations were so harmonious. Because the history maintains that conditions were above standard for the era, the frequency of labor disputes, especially in the mid-1880’s, is not accounted for. The work ignores the fact that the 1880’s were crucial years in American labor history, and that the packinghouse workers! efforts were part of the national movement for labor reform.
In fact, other historical sources for the late nineteenth century record deteriorating housing and high disease and infant mortality rates in the industrial community, due to low wages and unhealthy working conditions. Additional date from the University of Chicago suggest th
