Given its authoritative coverage of other science topics, the textbook's chapter on genetics is surprisingly tentative, which leads one to doubt the author's scholarship in that particular area.

Can which refer to a clause.??
The original sentence contains several errors. First, the opening modifier "given its authoritative coverage of other science topics" describes the textbook as a whole, yet the subject of the main clause is "the textbook's chapter on genetics." Second, the relative pronoun "which" is used here to modify the entire clause "the textbook's chapter on genetics is surprisingly tentative."
[color=#400000]"Which" must modify the immediately preceding noun only;[/color] it cannot modify the action of an entire clause, as it does here.
In the explanation stated above ( as per the mgmatCATs explanation )
"which" must always refer to a noun preceding it.
I doubt whether this statement is right! There are many other posts in this forum itself, wherein its explicitly stated that for a sentence of the type
X to Y, which... which may refer to X or Y depending on the context..
Pls explain.
