Question:
In this exercise, you used an onclick event handler to call
each function. Research the addEventListener() method, and
explain how you would use it instead of an onclick event
handler to call the functions.

Answer:
To use addEventListener(), I would replace the HTML onclick
attributes with ID attributes. I could then use addEventListener()
in combination with document.getElementById() to run a specific
function depending on which HTML paragraph is clicked.

HTML:
<main>
	<div id="questions">
		<p id="q1">How can I determine if a baby animal
		is an orphan?</p>
		<p id="q2">How can I tell if an animal has
		rabies?</p>
		<p id="q3">I found a baby bird that fell from
		its nest. Will the parents orphan it if I touch it?</p>
		<p id="q4">How can I volunteer?</p>
	</div>
	<div id="answer">
		<h2>Answer:</h2>
		<p></p>
	</div>
</main>

JS:
var q1 = document.getElementById("q1");
q1.addEventListener("click",ans1);
var q2 = document.getElementById("q2");
q2.addEventListener("click",ans2);
var q3 = document.getElementById("q3");
q3.addEventListener("click",ans3);
var q4 = document.getElementById("q4");
q4.addEventListener("click",ans4);
