Although it seems ______ that there would be a greater risk of serious automobile accidents in densely populated areas, such accidents are more likely to occur in sparsely populated regions.
【正确答案】 B
【答案解析】- 方程等号：although尽管，表示让步转折，句内取反。
- 强词和对应：根据题意，人口密度大的地区有更大的交通事故风险是空格的，而后文提到在人口稀少的地方事故是更加容易发生的。densely populated areas和sparsely populated regions根据although取反，所以likely指向空格，空格填一个不改变句子的逻辑方向的词。paradoxical矛盾的，axiomatic不言自明的，anomalous异常的，irrelevant不重要的，portentous凶兆的。答案选B。
