The system automatically selected that answer for use as a review audit because it was deleted after being flagged as spam or rude or abusive. I know this because 10k users can view deleted posts, but posts that get one or more "red flags" before being deleted have their bodies hidden until one clicks through to the revision history:
In this case, the flag ...
The new review icon (which only appears when you have 500 reputation or more) looks like this:
or in context (ooh look a tooltip!)
it's been suggested that it looks kinda like a stapler... This icon may be getting changed soon, but it's going to be in the same place and it's not going to have any text saying "review" :(
When you click the button, you get ...
It's a weakness in the audit system. One of many. Don't worry about it, these audits are only there to catch people who are clicking blindly to get badges. Failing one every now and then is not an issue, just shake your head at the stupidity of all automated systems and move on to the next review item.
So to do this (I just found) is actually really easy, and I'm glad I didn't post the question :)
Up at the top is a button that says rendered output, click that and it automagically changes to the rendered html.

There are two options.
To leave the question closed, since it is still not clear.
To reopen the question and add the OP's answer as a community wiki answer.
I vote for the second option, because this answer may have some value for someone who meets the same problem. It is unlikely though.
I normally click the back button and access the problem post directly (it will be linked), the perform the necessary actions on the question outside the review queue.
Also, don't worry about a mistake - it isn't binding, it needs (3?) more wrong votes to keep it open. (And I've just flagged etc. that one!)
But, as Seth says - do go back!

The question, and the answer content:
Try using a live distro to edit or remove your /root/.bashrc.
The answer is correct, but it's far from being a good answer. The question already knows it's a broken /root/.bashrc file so the answer might as well just say:
The OP figured that out and restored the file from /etc/skel/ in the end. They ...
There are two ways to see the review queues:
through the drop-down menu at the top right of pages
the "all queues" page, which can be accessed by clicking "all queues" in the drop-down menu
the drop-down menu shows only the queues you have access to
the "all queues" page shows all queues and greys out the queues you don't have access to
The threshold, being the queue currently bigger than 1K, "has been increased" to 40 already; this is clear just by looking at the daily late answers review stats, however: How come my vote cap for "First Posts" is lower than others?;
Also, it will shrink: since when I asked about why the queue increased yesterday, it shrunk by ~800 questions ...
Once you pass the 10k reputation mark and unlock the moderator tools privilege, the number will stop showing only the suggested edits, but instead show the - almost - total number of all available possible reviews.
For more details, you can check the following question/answers: What does the number next to the review link in the top bar actually mean?
As one goal of our edit reviews is to educate people to make better edits I tend to "accept and improve" only rather small omissions.
When someone suggests an edit where only the easy (spottable or doable) part has been done I rather use "reject and improve".
It's an audit.
It's actually based on a question that was deleted a while ago so no, you can't do anything to it. Just mark it for closure (because it was a bad question with no detail and no updates) and you'd have passed.
