Hi,

the answers to these questions are pretty standard and should be present in your school's notes or commercial notes. So there's no point for me to regurgitate everything from the notes.

Do check your notes.

As for (4), I don't understand what you mean. The centre portion of this article might help:

Finally, do not open multiple threads. One thread will do.

Thanks :)
