Assume you are running the following code in the Python interpreter:

class Account:

num$\_$of$\_$accounts $=0$

def $\_\_$init$\_\_($self$,$ id$)$:

self.id $=$ id

Account.num$\_$of$\_$accounts $+=1$

def register$($self$,$ student$)$:

self.student $=$ student

return f'Registered: $\{$student$\}\text{'}$

Without using the Python interpreter, what is the output of the following statements when the code is executed?

$>>>$ x $=$ Account$("$AT$5")$

$>>>$ x$.$register$("$Peter Pan"$)$

$[$Answer $1]$

$>>>$ Account.register$($self$,$ "Jane Doe"$)$

$[$Answer $2]$

$>>>$ Account.register$($x$,$ "Jane Doe"$)$

$[$Answer $3]$

$>>>$ Account.register$("$Alex Matthews"$)$

$[$Answer $4]$

$>>>$ w $=$ Account$("$LP$9")$

$>>>$ w$.$register$("$Lily Smith"$)$

$[$Answer $5]$

$>>>$ z $=$ Account$("$EY$7")$

$>>>$ w$.$register $=$ z$.$register

$>>>$ w$.$register$("$Harry Potter"$)$

$[$Answer $6]$

$>>>$ w$.$student

$[$Answer $7]$

$>>>$ z$.$student

$[$Answer $8]$
