Not sure why my answer is incorrect. Is 'body' not the name of the tag?

I know that document.getElementsByTagName returns an HTML collection to the body variable listed. I put 'body' as the tag to grab, but it is saying my answer is incorrect.

You're right, body is a tag name - the key here is the hint on the question, which says that getElementsByTagName returns a collection. There might only be one body, but if you selected another element tag like h1, there could very well be multiple, which is why a collection is returned, even if there's only one match.

It should pass if you add [0] to indicate the item at index 0 - document.getElementsByTagName('body')[0]

document.getElementsByTagName('body') returns an array.

document.getElementsByTagName('body')[0] returns the body html.

Play around with it in the Chrome Developer Tools console!
