参考答案

正确答案：C
解析：这是一道细节理解题。根据原文第四段中萨姆森博土所言“I think the artists knew very well that the etchings would hardly be visible except early in the morning．We can therefore deduce that the chamber wasu sed for rituals involving animal worship，and that they were conducted just after dawn as a preliminary to the day's hunting．”(我认为艺术家深谙这样一个道理，那就是蚀刻画只有在清晨才清晰可见。因而我们可以推断，该洞穴用于举行动物崇拜仪式，这些仪式总是在清晨举行，之后就开始一整天的狩猎活动。)deduce等于infer，可以说deduce sth from sth，意即演绎，推断，例如：Detectives deduced from the clues who had committed the crime．(侦探根据所掌握的线索推断出作案者。)而选项C“The images were intended for early morning rituals．”(这些图画是为清晨仪式而画的。)与原文符合，故选C。
