An HTML div element contains lists of endangered species grouped by continent and the species population status.
<div>
<ul data-continent="North America">
<li data-species="California condor">Critically Endangered</li>
<li data-species="American bison">Near Threatened</li>
</ul>
<ul data-continent="Europe">
<li data-species="Cave bear">Extinct</li>
</ul>
</div>
Write a function that returns how endangered a species is on a particular continent. For example endangeredSpecies('North America', 'American bison') would return 'Near Threatened'.
