Because that's what you're looking down on. You don't move, but you watch the Earth rotate for a year, how many times does it rotate on its axis while you're observing?
Do we also assume for this problem that the earth is a perfect circle/sphere?

Well the Earth is Earth shaped, it's not a perfect sphere as you know. But that shouldn't matter, it still rotates, and if it was a flat-earth it'd still be rotating.

I meant the sun, sorry. After all the earth revolves around the sun, and that revolution might affect the answer, right? Or still irrelevant?

Well of course it matters, we're talking about the real Earth after all, not a theoretical body in space. But In answering that let me also give away the next incorrect answer which 3 out of 10 people so far chose: "It doesn't rotate, it spirals along a cylinder". The earth doesn't spiral at all so that should be a dead give-away that the answer was wrong, but it does travel along a cylindrical path (not a physical cylinder, of course), significant enough that over the course of a human life we travel quite a bit further in that direction compared with our orbit. But with that said, the Earth rotates, it doesn't spiral, and there's no physical cylinder so on every level that is an incorrect answer.

Since I didn't specify, you can choose either so long as you can find an answer that you believe to be correct. You can choose to answer the question of "how many times does the earth rotate on its axis in a year" or "how many times does the earth rotate around the sun in a year".
According to my understanding rotation happens around a central axis within the body doing the rotating, therefore the earth's elliptical path round the sun isn't a rotation.

As I've mentioned, the question is indeed: how many times in 1 year does the Earth rotate on its axis?

In my answer, I assumed the definition of 1 year being the time the earth needs to circle the sun once and return to the previous position as seen from a nonrotating outside observer.

That's not an assumption, that's the definition.
