我认为 这里的 serving as a platform to oversee the behavioue of officials.是非限制性 定语
修饰 Microblog 相当于一个非限制性定语从句 属于分隔式 定语
= which serves as a platform.
原句 也可以是 Microblog ,serving as a platform to oversee the behavioue of officials,has made a great difference
知道为什么 不能选B.to serve 了吧?
选B 是目的状语 与前面的句子意思 不符

你是说微博的目的是监督官员的行为??并且前面用的现在完成时,一般来说现在完成时之后不用to do

前面有逗号,表示另一个独立结构。seving as a platform to oversee the behaviour of officials是现在分词作伴随状语。
希望能帮助你,有疑问再追问,满意请点“采纳”

因为只是一个固定短语叫做make a difference in sth在某方面有成就 所以后面可以跟名词 如果是动词必须用ing形式。希望我的回答能帮助到你。
