Question

a main reason that the age of revolutions initially failed to achieve widespread change in some nations of europe was because
revolts were poorly organized.
few people supported the revolutions.
liberal reforms were impractical in daily life.
monarchs reasoned with the rebels.

Explanation:

在欧洲革命时代，一些国家革命未能实现广泛变革，主要原因之一是起义组织不善。革命需要有效的组织来协调行动、凝聚力量等，若组织混乱，就难以推动变革。而“few people supported the revolutions”不符合史实，当时有不少人支持革命；“liberal reforms were impractical in daily life”不是主要原因；“monarchs reasoned with the rebels”也不符合当时君主对革命的态度（多是镇压而非理性沟通）。

Answer:

revolts were poorly organized.
