原文：
Yet the critical campaign I pondered did not take place, partly because of external hindrances, but also because of my intervening doubt. In fact, the Head Juries were rather well suited to the most recent cultural viewpoints and interrelationships of human activities. There could have been no other plan devised for the general Industrial Exhibitions of 1851.

參考答案：

然而我所認為的關鍵性措施并未被采取，部分是由于客觀原因，但部分也是由于我在兩者間的猶豫。事實上，“首席評審委員會原則”更符合最近的文化觀點以及人類活動的相互影響。再也找不到為了1851年這種綜合性工業博覽會而設計的其它計劃了。
