What does this question want?

It just asks how I'd select it and I've tried several ways of answering first with these 3

document.getElementsByClassName('body'); document.getElementsByClassName('body') 'body'

Hi Zack,

document.getElementsByTagName returns an HTMLCollection — basically, something that resembles an Array. So, if you wanted to assign <body> — an HTMLElement — to a variable body, you'd have to first get the initial element out of the HTMLCollection returned by document.getElementsByTagName. Let me know if that doesn't clear it up.
