1. It was forged in the fires of Mount Doom.

2. When someone takes the Ring, the Ring will start to slowly bring the holder into its power, so when Isildur took it, he fell into its power and wasn't able to throw it into the fire where it was forged.

3. The whole kingdom was destroyed, and Aragorn is the only confirmed person to be from Arnor (He is related to Isildur).

4. Boromir is a traveler, and he went to the council to seek counsel.

5. He holds the Broken Sword and is Isildur's heir.

6. Saruman is a wizard who knew about the Rings, as the book said ' he was reached under the lore of the rings', at least I think that's was the book said. He had joined the dark side, and since Gandalf was technically his enemy, it would make sense to capture him, right?

7. I highly doubt that Tom Bombadil will keep the Ring safe, he walks around merrily as if everything is fine, he could easily be surprised by the Black Riders and have the Ring stolen from him.

8. Both of the gifts will help Frodo protect himself, so I think Bilbo just wanted Frodo to be safe.

9. The elves thought that the dwarves started the evil, so they were no longer friends.

10. There was lots of snow that piled up, and they couldn't pass through, I think.
