What the title says. Consider this example:
"There are a lot to visit when going sightseeing. One of them being tourist attractions."
Is "One of them being tourist attractions." a complete sentence?
My teacher says it isn't as it is lacking a verb. In my opinion, it is complete with the verb "being" but I can't seem to dissect the underlying grammar behind this. Best I can do is "being tourist attractions" is a participle phrase headed by "being" and is modifying the word "them", which is in turn replacing "a lot to visit". Any help would be greatly appreciated! Thanks a lot in advance!
