The charity group Plan International says 600 million Asian children are deprived of one of the seven basic needs used to define poverty, including food, safe water, shelter, health and education. And it says 350 million children, equivalent to the population of the European Union, are deprived of two or more basic needs, classifying them as absolutely poor. The group's executive director, Tom Miller, compares these figures to those of the victims from the earthquake and tsunami that devastated parts of southern Asia eight months ago. "Those numbers are absolutely staggering. The world has focused very much on Asia through the tsunami. But in many ways, what we're talking about is, this is a silent tsunami that is happening every single day." The group, basing its figures on United Nations statistics, says some Asian countries, like China and parts of Southeast Asia, have considerably reduced their numbers of poor children. But it says significant populations of poor people remain in isolated rural areas and among ethnic minorities. According to the news, which of the following is not among the basic needs used to define poverty？ A．food B．health C．education D．freedom

A．settle into B．settle down C．settle D．settle upon
