Given the following code:

function big$()\{$

function sub$1()\{$ var x $=7$; $\}$

function sub$2()\{$ var y $=$ x; $\}$

var x $=3$;

$\}$

If the language employed

dynamic

scope rules for its variables, then the value of the variable y in sub$2$ would be defined by the spacial relationship and would result in the value of

$[$ Select $]$

$.$ If the language employed

dynamic

scope rules, then the value of the variable y would depend on the order of calls: if sub$2$ were called from big, then it would be

$[$ Select $]$

$,$ if sub$2$ were called from sub$1,$ it would be
