Why was Claire in the hut? - She was brought there by her daddy, Christian Shephard (so yes, it was him) he appeared to her in episode 10, she left the baby, and followed him.
How the hell are they gonna move the island? - Honestly, I have no idea, it could be something with magnetism but óne thing is certain: they are not gonna push it away.
What was the thing strapped around that guy Martins arm? - Again, no idea, first I thought it was a bomb, but that's unlikely, maybe something to prevent him from getting sick?
How come de dead doctor body turned up at the island before he was killed? - Because of the time difference, it's hard to tell how much exactly because I don't know if the island is moving or not, so it could be a constant difference or not.
I hope I could help!
