None are normal. They may not be a perfect reversal, but, none are a perfect normal.

Flipping is the measure of whether the thing is reversed. If it has to be flipped (and then possibly rotated also) for it to appear normal then it is reversed. If it can simply be rotated within the two dimensions that it is presented in then it is normal. So when she says, “no flipping”, it is almost an entrenched joke because it is a limitation on how many dimensions you are allowed to manipulate in order to solve the problem. Personally it is easier for me to flip than it is to rotate so I solve it by flipping (unless the letter is oriented just right, then it is easier to rotate). Rotation works fine and is a two dimensional solution. I think that the inclusion of flipping makes it more interesting as long as you watch yourself rotating or flipping and notice your minds tendency to take the path of least resistance, but I have always thought that watching the problem solver solve the problem is vastly more interesting than the problem itself.
(Just thoughts, enjoy!)

We had assumed readers would see Pascale’s correction in the Comments section…but clearly that didn’t do the trick, so we have corrected the answer itself. Thank you.

So…when is the website going to be fixed to reflect the correct answer? This has been going on since March. It’s now November. ;^)

The 5 in the first row is reversed. The 5 in the second row is normal. Compare the both and find the answer.

BOTH the 4 and 5 are reversed in the first row. The 7 is okay. This must be a test to see how many people are paying attention.

I agree with a lot of you, the 5 in the first row is reversed… You can check it copying it in a paper and then turning it around…

Sammy, indeed, physical and mental exercise go best together
