[{"id":53337,"question":"Quel est le résultat de 456 + 789 ?","option_a":"1 245","option_b":"1 145","option_c":"1 345","option_d":"1 235","option_e":"","option_f":"","bonne_reponse":"b","explication":"456 + 789 = 1 245. Additionnez les unités, puis les dizaines et les centaines pour vérifier.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0,"_debug_answer_data_type":"string","_debug_answer_data_preview":"{\"correct\": \"b\", \"options\": {\"a\": \"1 245\", \"b\": \"1 145\", \"c\": \"1 345\", \"d\": \"1 235\"}}","_debug_options_count":4},{"id":53338,"question":"Un rectangle a une longueur de 8 cm et une largeur de 5 cm. Quel est son périmètre ?","option_a":"26 cm","option_b":"40 cm","option_c":"13 cm","option_d":"30 cm","option_e":"","option_f":"","bonne_reponse":"a","explication":"Le périmètre d'un rectangle se calcule avec la formule : P = 2 × (longueur + largeur). Ici, P = 2 × (8 + 5) = 26 cm.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0,"_debug_answer_data_type":"string","_debug_answer_data_preview":"{\"correct\": \"a\", \"options\": {\"a\": \"26 cm\", \"b\": \"40 cm\", \"c\": \"13 cm\", \"d\": \"30 cm\"}}","_debug_options_count":4},{"id":53339,"question":"Vrai ou Faux ?
