选项 A、thorough
B、scientific
C、individual
D、ridiculous
答案 B
解析 篇章题。上下文理解题。thorough意为“全面的，彻底的，完全的”，如：He made athorough search for his subject books．他彻底地查找了有关自己学术专业的书籍。scientific“科学(上)的，科学性的，合乎科学的”，如：scientific management科学的管理方法。individual意为“独特的，特别的，特有的”，如：Each variety of melon has itsindividual flavor and texture．每一种瓜都有自己独特的味道和口感。ridiculous意为“可笑的，滑稽的，荒谬的”，如：He eventook that ridiculous suggestion．他甚至采纳了那个可笑的建议。既然前面交待了温室气体对气候的影响不是通过常用的观察而得，那么这个结论的可信度有可能受到质疑，因此，非常有必要指出这个结论的来源具有科学合理性，因此，选项scientific为最佳答案。thorough(全面的，彻底的)也说得通，但没有“符合科学”更具说服力。individual(独特的)在表可信度上没有说服力，而ridiculous更是表对这种来源的否定态度，与题意相抵触。
