Explanation:

1. Oil and natural gas are not exhausted (A is wrong); biofuels can have environmental impacts but this is not a reason to invest in alternatives (B is wrong); renewable energy infrastructure has upfront costs (D is wrong). Governments and private entities invest in alternative energy to develop and profit from emerging green technologies.
2. Foreign aid is typically resources given to nations in need, while trade agreements are formal contracts for mutual trade of goods/services. Option A misdefines trade agreements; B mixes up the nature of the two; C incorrectly labels foreign aid as unofficial trading.
3. After WWI, the US pursued isolationism, rejecting the League of Nations to avoid being drawn into foreign conflicts. By WWII, US leaders recognized isolationism was no longer viable, as global interdependence and the threat of future wars made UN membership necessary for US interests and global stability. Option A is incorrect (US did not see UN as enforcer initially); C is wrong (UN was larger than the League); D misrepresents the League's core purpose (it was focused on peace, not militarism).

Answer:

1. C. They want to make money on new technologies.
2. D. Foreign aid is the offering of various resources to countries in need; trade agreements are contracts made between two countries that want to trade goods.
3. B. In 1919 the United States wanted to protect its independence and return to a policy of isolationism, but by 1945 US leaders realized that isolationism was no longer in the country's best interests.
