同学你好，
第三题定位词是concept/physical objects对应的是第五段:abstract idea/particular objects/independent of
我们看到第五段第一句话说....see that a number is really an abstract idea....最后一句说，...independent of the object being referenced, the inidividual is....from there, to arithmetic
题干中concepts和physical objectss互为近义词，所以正确答案是C
