[{"id":5765,"question":"Quelle est la formule de l'aire d'un triangle ?","option_a":"A = base × hauteur","option_b":"A = (base × hauteur) \/ 2","option_c":"A = π × rayon²","option_d":"A = côté × côté","option_e":"","option_f":"","bonne_reponse":"B","explication":"La formule correcte de l'aire d'un triangle est A = (base × hauteur) \/ 2. C'est une notion fondamentale en géométrie.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":5766,"question":"Vrai ou Faux ? La photosynthèse se produit uniquement la nuit.","option_a":"Vrai","option_b":"Faux","option_c":"","option_d":"","option_e":"","option_f":"","bonne_reponse":"B","explication":"La photosynthèse nécessite la lumière du soleil, elle se produit donc principalement le jour.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":5767,"question":"Quel est le résultat de 3 × (4 + 2) ?","option_a":"18","option_b":"24","option_c":"14","option_d":"9","option_e":"","option_f":"","bonne_reponse":"A","explication":"En appliquant la règle des priorités, on calcule d'abord la parenthèse : 4 + 2 = 6, puis 3 × 6 = 18.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":5768,"question":"Vrai ou Faux ?
