问题 Specific direction is characterized by ______.
Market incentives are useful in that they help ______.
选项 A、raise commodity prices to give government a bigger revenue
B、the government encourage more researchers to make technological innovations
C、raise oil prices to cut gasoline consumption and protect our environment
D、the government give allowances to private enterprises to build more advanced highways
答案B
解析 由题干中的Market incentives定位到原文第三段首句Market incentives are the deliberate manipulation of the market by the government to control how a particularly technology is distributed and used．[精析] 推理判断题[考频：66]。原文第三段在讲市场激励机制的作用，其中提到通过收税的方式把钱分配出去，其中之一就是给予私人研究人员补贴并加强知识产权法的力度，给技术开发者更多激励。由此推知给他们激励实际上就是鼓励他们进行更多的技术革新。故B)正确。[避错] 原文例子虽然提及提高汽油税，但目的是对公路的改善予以补贴帮助，并没有提及“提高商品价格以使政府获得更高回报”，可排除A)；原文只提及提高汽油税，并没有提及“帮助提高石油价格以降低其消耗并保护环境”，排除C)；原文虽提及“给予私人研究人员补贴”，但“帮助政府付给私企补贴以修建更多的高级高速路”并没有在原文出现，排除D)。
