问题 ______several hypotheses have been advanced for the disappearance of the dinosaur, no conclusive evidence supports any of them.

选项 A、Despite
B、In spite of
C、Although
D、In spite of the fact

答案 C

解析题干：尽管关于恐龙灭绝的原因人们已经提出了几种假设，但是没有一种有确切的证据。本题测试词组。although是连词，引导让步状语从句。despite和in spite of为介词和介词短语，不能接句子。in spite of the fact后如果接同位语从句必须有that，不能省略。故选C。
