遇到不懂的问题可以先查字典哦~~

verb
[V]
1
~ (in/among sth)
普遍存在；盛行；流行
to exist or be very common at a particular time or in a particular place

地方监狱的普遍状况让我们震惊。

这些信念在某些社会群体中仍很盛行。
2
~ (against/over sth)
(formal) (of ideas, opinions, etc. 思想、观点等) 被接受；战胜；压倒
to be accepted, especially after a struggle or an argument
同义词： triumph

正义必将战胜暴虐。
Fortunately, common sense prevailed.

3
[V] ~ (against/over sb)
(formal) （尤指长时间斗争后）战胜，挫败

所以这里的意思应该是“某观点很流行”~~~作为不及物动词放在句尾
希望有所帮助
