'This event was the base of all problems that Romeo and Juliet soon face, one of them being Juliet’s unwanted marriage with Paris.'
I realise the sentence is ungrammatical, but I didn't write it.
1) What is 'being' in this sentence? It could be replaced by 'is', so I assume it is a present particple?
2) If it is a present participle, then I assume the italicised words are a non-finite clause? And, therefore, the the comma there is fine; that is, it is not a run-on sentence?
3) Is this correct? If a past participle is the only verb in a sentence, then it is, in fact, a verb in the past form, and it is therefore a finite verb....
4) Is this correct? A present participle can never be a finite verb; it needs to have an auxiliary verb....
Thanks a lot in advance.
