A．an indication of a basic change in human nature
B．based on reasonable principles
C．fresh and acceptable to ordinary people
D．more of a transient phenomenon than literature
参考答案D
解析:推断题。通读全文，根据第一段中的With regard to futurist poetry…it can hardly be classed as literature．和最后一段This…can hardly be classed as literature．可知，作者反复声明未来主义诗歌不是文学。最后一句 The whole question is really this：have we essentially changed?作者用反问句形式表达肯定的观点：人们没有变化。由以上分析可推断作者认为未来主义诗歌是一种暂时的现象，并非文学，所以答案应该是D。
