Hi! Really need help...

Hey, my name is Ampersand, I'm new here..

I need to know a few things, can anyone out there please help me? I'm in a trivia contest, and I'm stumped on a few of the questions.

1. How long did Aragorn reign after the War of the Ring?

2.What is Elrond's relationship to Galadriel? Are they related or anything?

3. What is Saruman's name in Elvish?

All help would be greatly appreciated.
