Information is a non-countable noun (you can't have 4 informations), so it is neither singular nor plural. The correct usage is "information" without the 's'. More info here: https://english.stackexchange.com/questions/117552/why-does-information-not-have-a-plural-form So actually, neither one of your sentences is correct. You can't have two informations; it doesn't make any sense. Maybe you mean "two pieces of information"?
