be enough to do的语法分析

Photographs taken by roadside cameras will soon be enough to prosecute drivers for speeding.

问题一：enough是做代词吗？to prosecute drivers for speeding修饰enough?

能不能理解为enough是形容词，后面to do是做形容词宾语做补充说明呢？

问题二：被for sb to do sth不定式复合结构修饰表示结果这句话是什么意思？

摘自老师曾经对我问题的回答：

enough可以是副词、代词或形容词/限定词。

当enough直接作主语、宾语、表语或宾补时，通常enough被认为是代词。

网友的下述句子中，enough就是代词作宾补，enough本身又被more than前置修饰表示程度，被for sb to do sth不定式复合结构修饰表示结果。句子分析如下：

This（主语）, and the good archbishop's impressively prominent nose（插入语）, might be thought（被动语态谓语） more than enough for his peers to have nicknamed him 'nosy Parker'.（主语补足语，中心词为代词enough）

这个句子改为主动语态，基本结构为：

People (主语）might think（谓语） this（宾语） enough for his peers to have nicknamed him "nosy Parker".（宾语补足语）
