I can’t decide when to use plural in these expressions.
For example:
What type of tourists go to Bali? – sufers, yoga enthusiasts, sun worshippers
What types of tourists go to Bali? – surfers, yoga enthusiasts, sun worshippers
What type of tourist goes to Bali? – surfers, yoga enthusiasts and sun worshippers
As far as I can see it doesn’t make any difference as it doesn’t change the answer.
