Could someone help me with the following:

"Explain why your age can affect the hours you work or the type of
work you are allowed to do."

Many thanks.

Mihilism,
Your four questions look very much like homework of some kind,
something G-A doesn't like to have answered here (see the FAQs).  If I
were you, I wouldn't wait for someone to try to answer your questions.
Good luck, Myoarin
