[考点] 词义辨析
本题要求考生判断空格处应填入的适当的动词，使句子连贯。本句解释集市日城市变得更加拥挤的原因——方圆24公里或更远处的农民赶来贸易。from within a (2) of 24 or more kilometers这个介宾短语在修饰农民，这个短语中空格处确是名词，这个名词既能与within搭配，又能和后面的表示距离的修饰成分搭配，表示“24公里或更远的……”，只有C选项能同时符合这双重判断标准，填入后表示“来自方圆24公里或更远处的……”，因此C选项正确。
[干扰项分析] A选项词义差别较大，属于形近词干扰；B选项与距离无关，虽然extent有“(大片)区域”的意思，但往往用square kilometers(平方公里)来修饰限定；D选项也用square kilometers来修饰限定。
