单选题A quality education is the ultimate liberator. It can free people from poverty, giving them the power to greatly improve their lives and take a productive place in society. It can also free communities and countries, allowing them to leap forward into periods of wealth and social unity that otherwise would not be possible. For this reason, the international community has committed itself to getting all the world’s children into primary school by 2015, a commitment known as Education for All. Can education for all be achieved by 2015? The answer is definitely “yes”, although it is a difficult task. If we now measure the goal in terms of children successfully completing a minimum of five years of primary school, instead of just enrolling for classes, which used to be the measuring stick for reducation, then the challenge becomes even more difficult. Only 32 countries were formerly believed to be at risk of not achieving education for all on the basis of enrollment rates. The number rises to 88 if completion rates are used as the criterion. Still, the goal is achievable with the right policies and the right support from the international community. 59 of the 88 countries at risk can reach universal primary completion by 2015 if they bring the efficiency and quality of their education systems into line with standards observed in higher-performing systems. They also need significant increases in external financing and technical support. The 29 countries lagging farthest behind will not reach the goal without unprecedented rates of progress. But this is attainable with creative solution, including use of information technologies, flexible and targeted foreign aid, and fewer people living in poverty. A key lesson of experience about what makes development effective is that a country’s capacity to use aid well depends heavily on its policies, institutions and management. Where a country scores well on these criteria, foreign assistance can be highly effective. In the first paragraph, the author suggests that a quality education can______.
