This question actually refers to body parts: otoliths are small structures in your inner ears (in the semicircular canals, so this part is correct) that shift when you move - to help you sense your body position (so this part is also true).
But they're not exactly stones - they are small particles, so that's why the statement is false.
A push factor would be something like war or famine or something. A pull factor would be something like a job or new opportunity, its usually for financial reasons in my opinion. Hope this helped!
