美国田纳西州的

That's what our Founding Fathers did after winning independence, when they tied together the economies of the thirteen states and created the American market. That's what Lincoln did in the midst of the Civil War, when he pushed for a transcontinental railroad, incorporated our National Academy of Sciences, passed the Homestead Act, and created our system of land grant colleges. That's what FDR did in confronting capitalism's gravest crisis, when he forged the social safety net, built the Hoover Dam, created the Tennessee Valley Authority, and invested in an Arsenal of Democracy. And that's what Kennedy did in the dark days of the Cold War, when he called us to a new frontier, created the Apollo program, and put us on a pathway to the moon.

我们的开国元勋们在赢得独立后就是这么做的，他们把13个州的经济结合起来，开创了美国市场；林肯在南北战争期间就是这么做的，他推动修建横贯大陆的铁路，成立了国家科学院，通过了《宅地法》，创立了由政府赠地的州立学院体系；富兰克林·德拉诺·罗斯福就是这么做的，面对最严重的资本主义危机，他打造了社会保障&安全网&，修建了胡佛大坝，创建了田纳西州河谷管理局，投资兴办了&民主兵工厂&；肯尼迪在冷战期间也是这么做的，他号召我们奔赴&新边疆&，制订阿波罗计划，引领我们奔向月球。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
