Though even if they understood it as 'using the geocentric model, how long does it take for the sun to go around the earth?' their answer would be wrong. That said the reason to prefer a model where the Earth is stationary but rotating over a model where the Earth is both stationary and non-rotating (but everything else is) is somewhat technical and not something I would expect everyone to get correct (though it's technically high-school level physics). Perhaps the main reason people would answer questions like that wrong is that frankly the most useful model for day to day activities is one where the Earth is completely immobile.
