“A ship lost at sea for many days suddenly sighted a friendly vessel. From the mast of the unfortunate vessel was seen a signal, “Water, water; we die of thirst!” The answer from the friendly vessel at once came back, “Cast down your bucket where you are.” A second time the signal, “Water, water; send us water!” ran up from the distressed vessel, and was answered, “Cast down your bucket where you are.” And a third and fourth signal for water was answered, “Cast down your bucket where you are.” The captain of the distressed vessel, at last heeding the injunction, cast down his bucket, and it came up full of fresh, sparkling water from the mouth of the Amazon River. To those of my race who depend on bettering their condition in a foreign land or who underestimate the importance of cultivating friendly relations with the Southern white man, who is their next-door neighbor, I would say: “Cast down your bucket where you are”— cast it down in making friends in every manly way of the people of all races by whom we are surrounded.” Booker T. Washington, 1895 In this passage, Washington is urging African Americans to A) start a new life in South America. B) work more closely with whites in the South.

There is a public debate between the three candidates for the U.S. Senate. During the debate, the topics of oil and energy are addressed. Each candidate expressed their view on the issue: Edgar Eisenhower: “We need to cut our dependence on foreign oil. Instead, let’s use the natural world around us. Think about the sun, wind, water, the heat of the earth, and the crops in our fields. These will make for affordable energy in the 21st century. We should fund research in those areas. Let us also increase tax credits for private investment in clean, renewable sources of energy.” Rebecca Roosevelt: “We need to cut our dependence on foreign oil and develop a national energy strategy. We should provide tax incentives for producing energy in the U.S. Let’s increase U.S. supplies of coal, oil, and natural gas. We should promote environmentally responsible exploration and development of oil and gas reserves. That includes federal land like Alaska’s National Wildlife Refuge. Let’s also advance clean coal technology.” Terrance Taft: “Looking at our energy supply is one thing—how we’re using it is another. We can drive smaller, more fuel efficient cars. We can invest in more efficient technology for our homes and businesses. These things add up and make a big difference. In fact, in several new buildings associated with Taft Inc., we address our energy needs with locally produced renewable energy. That wouldn’t be possible if we were using outdated, energy guzzling technology.” Often politicians will agree that something is a priority, but have very different recommendations on how to best address it. What would be the best example of this from the previous section? 1. Both Terrance Taft and Edgar Eisenhower agree that inefficiency is bad, but disagree on how to make things more efficient. 2. Both Rebecca Roosevelt and Edgar Eisenhower agree that we need to reduce our dependence on foreign oil, but disagree on the best way of doing so. 3. Both Terrance Taft and Rebecca Roosevelt agree that alternative energy is important, but disagree about which form would be the best to invest in. 4. Both Rebecca Roosevelt and Terrance Taft agree that developing alternative energy sources is important, but differ on the best way of doing so.
