Name one way Norway and Sweden are similar and one way in which they are different?

The languages spoken in Norway and Sweden are very similar,
although English is so widely used in Scandanavia (Norway, Sweden, Finland, Iceland and Denmark)
that Scandanvians often use it with each other.

Norway is a member
of the North Atlantic Treaty Organization (NATO), Sweden is not. Sweden is one of 27 members of
the European Union, Norway is not.
