1) One of the characters, H, has been repeatedly and severely beaten, with quite a few blows landing on his head. What I want to know is if this could possibly result in permanent hearing loss. If not, how long does head injury related hearing loss usually last?
2) H is also choked with a belt on several occasions. Would it be plausible for permanent loss of voice to occur from this? If not, what sort of injuries could cause permanent voice loss?
3) Because of the above reasons, H needs to learn sign language in order to communicate. How long would it take a reasonably intelligent 15/16 year old to learn sign language?
4) Is it possible to enter a Surrey primary school without a birth certificate? I found the website for that local authority, but the file was a PDF, which isn't supported by either my FireFox or my Vista so I can't read it.
