2. Go to the Rewards menu (where you can choose to place awards) and click on the X in the corner to close the menu.
3. Go to the Garbage Management menu (where you buy incinerators and so on) and click on the X in the corner to close the menu.

Tips

Tip: Start out slow, making sure never to expand faster than the
expected tax revenue growth. You're building a city, so slow and
steady wins the race.
Tip: Look to develop neighbor deals early on. Specifically, make
sure you have excess garbage capacity, then contract to handle
another city's garbage. Sure it's smelly, but it brings in
much-needed income.
Tip: SimCity 2000 veterans should read the tutorial. There are
enough subtle changes that invalidate some old strategies. Also,
the garbage dilemma is another new feature that needs to be dealt
with early on.
