faith, belief and tradition. With or without s. why?
I suspect that sentence fragment should read like this:
There are new immigrants from all over the world living in the communities.
You should use “s” because all those nouns should be plural. If the immigrants come from different places, that quite likely exposes natives not just to one different faith, belief or tradition but many. All three nouns have uncountable forms; however, I don’t find those uses likely here.
