例：在关于交通法规的一篇文章中写到Trucks are not allowed to run on this road. 问题是: Cars are prohibited on this road. 答案应为：F。但不少考生会误选NG，问题在于考生没有做进一步的`简单推理，没能看出文中说的卡车禁行是针对其它机动车辆不禁行而言。当文中或题目涉及到对立的概念时，如：多与少、生与死、战争与和平等，尽管作者可能仅提到其中的一个方面，但其另一个方面则是不言而喻的。如果不是对立或对应的两者, 而是多种可能, 应为NG。这种推理是考生做出正确判断的重要方法。这样的考题有时颇有一定难度，考生容易误作NG来理解。又例：
In times of peace, the Olympic Games have taken place at four-yearly intervals since its inception in 1896.
Q: The Games have taken place every four years since it was revived in 1896.
