    That's what we all want.
    Maybe you should apply more care in at least copying the question correctly. These are not sensible questions yet alone sentences. Maybe you try again asking what you don't understand and please show some effort you have put into answering these questions yourself (Linking to wikipedia is not quite enough.)
