[{"id":90001,"question":"Quel est le résultat de l'opération 45 + 27 ?","option_a":"62","option_b":"72","option_c":"82","option_d":"52","option_e":"","option_f":"","bonne_reponse":"b","explication":"45 + 27 = 72. Additionnez les unités (5 + 7 = 12) puis les dizaines (40 + 20 = 60), puis additionnez les résultats : 60 + 12 = 72.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0,"_debug_answer_data_type":"string","_debug_answer_data_preview":"{\"correct\": \"b\", \"options\": {\"a\": \"62\", \"b\": \"72\", \"c\": \"82\", \"d\": \"52\"}}","_debug_options_count":4},{"id":90002,"question":"La multiplication est une opération commutative.","option_a":"Vrai","option_b":"Faux","option_c":"","option_d":"","option_e":"","option_f":"","bonne_reponse":"a","explication":"Vrai. La multiplication est commutative, ce qui signifie que a × b = b × a.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0,"_debug_answer_data_type":"string","_debug_answer_data_preview":"{\"correct\": \"a\", \"options\": {\"a\": \"Vrai\", \"b\": \"Faux\", \"c\": \"\", \"d\": \"\"}}","_debug_options_count":4},{"id":90003,"question":"Quel est le résultat de 120 ÷ 4 ?","option_a":"20","option_b":"30","option_c":"40","option_d":"50","option_e":"","option_f":"","bonne_reponse":"b","explication":"120 ÷ 4 = 30.
