and more.
Reading this highly interesting article prevents from asking questions like those asked in this thread at start - provided that one understands what is written.
I am to lazy to
- explain why the questions have been not on the point
- explain how the right questions would have looked like
- and to answer these questions .
Not for someone with this special attitude. :)
Would be wasted time anyways.
