Final answer:
Marie Antoinette kept busy at Versailles by indulging in her fondness for roses, as reflected in the garden with over two thousand roses and the painting 'Marie-Antoinette with the Rose' by Élisabeth Louise Vigée-Le Brun.
Step-by-step explanation:
Marie Antoinette spent her time at Versailles engaging in various activities that reflected her royal status. Despite facing widespread criticism for her opulent lifestyle, she found solace in her love for roses, having planted over two thousand roses in one of the gardens.
The artist Élisabeth Louise Vigée-Le Brun, who painted numerous portraits of the queen, such as Marie-Antoinette with the Rose, depicted her adorned with elegant silk clothing, a powdered wig, and a feathered hat, standing out against the darker garden backdrop. Marie Antoinette's portrayal with a rose symbolized her appreciation for the flower and represented her affinity for luxury and nature amid turbulent times leading up to the French Revolution.
