一、这些题目是LSAT的。
二、doris：你的问题我跟坛主问一下，因为我也不知道为什么。咱们论坛是不删贴的！
三、现在对这题只有一个字---恨！哈哈！这题的答案最难确定之处在于：B与D，但D与政客的言论有写一致；B主要是没有驳斥什么雪茄的论点，但与政客的论点相斥；另外，A可是与政客的观点不矛盾，实际上政客的观点是A的延伸。

斑竹，实在不好意思。A 选项，其实是P 观点的否命题，也就是说和P 不 consistent, /为何不选呢？


另外，请问这些是GMAT 题还是LSAT题，

谢了

关于第一题的解答请看：celeste的。

1、如果错的是那些----下面与上面犯的错误是一样---等类型的、GMAT一般不考的题，问题不大
2、你的作题时间是多少？是不是作题时阅读理解跟不上？

我也作LSAT，很郁闷啊，错误率一直都很高，50%左右，现在已经作了大概5套了，10个SECTION了，还错这么多，请问有什么好办法能提高一下吗？
我9月考，请问现在花时间做LSAT是不是不明智啊？
