I will give you a sentence describing a pedestrian, and you need to judge the gender of the pedestrian based on the sentence. You can infer from gender nouns or personal pronouns, if there is indeed no corresponding description in the sentence, just answer 'not mentioned'. 
By the way you need to format your answers as {"gender":'man'}, {"gender":'woman'} or {"gender":'nom'} format, and do not mention any other word except the required answer. Understand? Avoid using the following keywords: sentence, format, gender":'nom, pronoun
