Draw an E$-$R diagram for the following situation $($underline Primary Keys$)$:

This is a simplified model for reserving baseball tickets.

There are teams, which are identified by the team name. Teams are also located in a city.

Teams play each other in games, which occur on a particular date at a particular time. Games are

identified by a game ID$,$ and each game has exactly two teams that play in it$.$

A game is played in exactly one stadium.

A stadium is identified by its name, and is also located in a city.

Stadiums have seats, which have a section number, a row number, and a seat number.

Ticket holders reserve seats for a game. Ticket holders are identified by their name.

Some ticket holders are students $($students get discounts, but we are not including that in the model$).$
