- The film provides a deep（）into a wide range of human qualities and feelings.
- 科学不是宗教，宗教都主张信仰，所以主张信仰都不科学。 以下哪项最能说明上述推理不成立（）。
- 即使在古代，规模生产谷物的农场，也只有依靠大规模的农产品市场才能生存，而这种大规模的农产品市场意味着有相当人口的城市存在。因为中国历史上只有一家一户的小农经济，从来没有出现过农场这种规模生产的农业模式，因此，现在考古所发现的中国古代城市，很可能不是人口密集的城市，而只是为举行某种仪式的人群临时的聚集地。 以下哪项最为恰当地指出了上文论证的漏洞（）。
- 帕金森病是一种严重危害大脑的疾病。那些在体内不能生成细胞色素P405的人，和那些体内能生成这种细胞色素的人相比，在他们进入中老年后，患帕金森病的可能性要大三倍。因为细胞色素P405具有使大脑免受有毒化学物质侵害的功能，所以有害化学物质很可能是造成帕金森病的重要原因。 以下哪项如果为真，最能加强上述论证（）。
- 书最早是以昂贵的手稿复制品出售的，印刷机问世后，书就便宜多了。在印刷机问世的最初几年里，市场上对书的需求量成倍增长。这说明，印刷品书籍的出现刺激了人们的阅读兴趣，大大增加了购书者的数量。 以下哪项如果为真，最能质疑上述论证（）。
- 由于含糖饮料的卡路里含量高，容易导致肥胖，因此无糖饮料开始流行。经过一段时期的调查，李教授认为：无糖饮料尽管卡路里含量低，但并不意味它不会导致体重增加。因为无糖饮料可能导致人们对于甜食的高度偏爱，这意味着可能食用更多的含糖类食物。而且无糖饮料几乎没什么营养，喝得过多就限制了其他健康饮品的摄入，比如茶和果汁等。 以下哪项如果为真，最能支持李教授的观点（）。
- 自然数n满足（） （1）自然数n加上2后是一个完全平方数 （2）自然数n减去1后是一个完全平方数
