Suppose we want to develop software for an alarm clock. The clock shows the time of day. Using buttons, the user can set the hours and minutes fields individually, and choose between $12$ and $24-$hour display. It is possible to set one or two alarms. When an alarm fires, it will sound some noise. The user can turn it off, or choose to $$snooze$.$ If the user does not respond at all, the alarm will turn off itself after $2$ minutes. $$Snoozing$$ means to turn off the sound, but the alarm will fire again after some minutes of delay. This $$snoozing time$$ is pre$-$adjustable.

$1.$Draw the use case diagram for the scenario.

$2.$Write the use case description of the following use case $($Schedule Event$)$based on the above scenario.
