Passage Two [br] What does the author mean by "unknown unknowns cropping up" in Para. 11?
选项
答案
Unexpected uncertainties suddenly occurring.
解析
根据题干定位至第十一段。第十一段第一句提到,开发环节有很多不可避免的特征(指上文提到的有关成本的估算问题等),加上人们都有认知偏差,因此计划总不可能是完全精确的,第十二段也指出计划只能是一个最佳的可能情况,而不是一个确定的承诺,再结合unknown和crop的字面意思,可知该词组在此处的意思是“意外情况突然出现”,故答案为“Unexpected uncertainties suddenly occurring.”。
