Final answer:
Marie Antoinette's education focused on religious and moral principles to instill traditional values, prepare her for her royal role, and limit her influence.
Step-by-step explanation:
Marie Antoinette's education mainly focused on religious and moral principles rather than academic subjects like her brothers because it served multiple purposes. Firstly, it aimed to instill traditional values in her, as the future queen, to ensure she adhered to the norms and expectations of her role. Secondly, it aimed to prepare her for her royal role by emphasizing the importance of her duties and responsibilities as a monarch. Lastly, it may have been a deliberate strategy to limit her influence and discourage her from engaging in intellectual pursuits that could challenge the existing power structures.
