Ten questions

Q:Are there more goblins living in different mountains?

A: I think there might be, because not every goblin in the world would be in one mountain, and taking orders from one person.

Q:Why did gandalf bring bilbo and his friends to the wolves territory?

A:I think that gandalf might have been testing their skills and teamwork.

Q:Why does Beorn not have any silver/gold and very little metal?

A:Maybe it effects his bear/human body or he just can't get any.

Q:Why does Gandalf keep Beorn’s horse but make the dwarves send back the ponies?
A:maybe gandalfs journey was more intense and needed help to travel faster and farther.

Q:How big were the spiders and how many were there?

A: I think a few feet or so horizontally and vertically and i think a whole swarm of them.

Q:Are the elves and goblins enemies?

A:I think that they are because the goblins don't seem to be very friendly.

Q:Why could the villagers see the water dripping off bilbo when he is wearing the ring but they can't see if he is holding an object.

A:I am guessing that since the water is falling off of him and not touching him it is visible again.

Q:Why would Gandalf leave the dwarves on their own?

A:I assume that he had to be places and was testing the dwarves and he believes in them.

Q:What would the elves do with the dwarves if they had not escaped?

A:I think they would have just kept them as prisoners for their lives.

Q:Will Gandalf come back to help them on part of their journey?

A:I think that he will come back at least to help when they reach the dragon.
