The book was boring, and as stupid as the last one, punctuated by silly mistakes.
Is it unambiguous? Is it grammatical?
I'm asking if it's grammatical because I want to know whether you can offset a participle phrase at the end of a sentence like that, as it does not immediately follow the main clause. Is it ambiguous as to whether both books have silly mistakes?
I can't post the actual sentence I'm thinking about, sorry.
