First assign a variable to your Choice List. For example

<select id="listHomeCountry1" ng-model="homeCounrty">

Then simply use ng-show (doc)

<div id="div2" ng-show="homeCountry">

The above is also equivalent to:

<div id="div2" ng-show="homeCountry != null">

`ng-model="homeCountry"` will simply create a variable called `homeCountry` and bind it to the value of the SELECT. Read [this](https://docs.angularjs.org/api/ng/directive/ngModel) for more info. – SDekov Jul 13 '15 at 08:07
