问题 Kunz gave up software engineering mainly because he earned less than those in law or business field did. [br] American high school students sink almost to the bottom in a survey of math and science literacy because too many of the high school ______ in America are not qualified.
选项
答案 science and math teachers。
解析 根据题干中的信息词math and science literacy和qualified定位到第二个小标题下的第二、三段，可知在2003年一项国际数学和理科水平调查中，美国四年级学生表现良好，但高中生却几乎排在最后，问题不在于学校的预算，而在于美国高中有许多数学和理科教师不够资格，由此可得答案。
