参考答案
正确答案：B
解析：推理题。根据最后一段中的“…，but it cannot replace our public school systems because most parents are simply not available to provide home schooling．”可知，选项C和D可以排除。本题的关键还在于理解“are not available to provide”的含义，即它是指父母没时间还是指父母没时间?根据文中的第一句“Home schooling appears to be a great success for middle—class and wealthy families when oneparent is home most of the time．”可知，“Home schooling”需要两个条件，即父母需有钱和时间，而第三、五、六段陈述了随着“course materials and tutoring systems”的提升，“Home schooling”会变得很便宜，因而“are not available to provide”是指父母没有时间。故正确答案为B。
