"what's the rankings based on?"
and what's the difference between "me too" and "I'm also" ?
hmm and which is better: "you need to go there" or "you must go there"
#1 There is no agreement in number between subject and verb - "What is" is singular, "rankings" is plural.
#2 me, too = objective; I am, also = subjective. Essentially the same in meaning. The first is more colloquial than the second. [nb, note the comma]
I am happy with that answer.
Me, too // I am, also
But: I am also happy with that answer [note, no comma]
#3 "You need to" = there is a reason why you should do something.
"You must" = it is necessary to do something
