The passage says that all the other options could be the meanings of Human Obligations. According to the passage, human obligations include acquiring knowledge ('to be able to think clearly and objectively so that false doctrines cannot gain ground', 'to see through nonsense'), behaving in a disciplined manner ('to observe restraint'), thinking clearly ('to be able to think clearly'). It does not include 'making other feel that you are always right' as it includes 'duty to resist'.
