no ur answer is correct but it may be
because they are poor and they didnt have enough land to cultivate or they do not hve sufficient money to cultivate their land and no any money lender allowed to give them money thats only many families of farmers cultivate small plots of land
Many families of farmers cultivate such small plots of land because
