How should the AI adapt the complexity of its answers based on grade level?

The AI should adapt complexity as follows:

• 1-4 grades: maximally simple words, absence of complex terms.
• 5-9 grades: basic school level, using terminology from the current curriculum.
• 10-11 grades: advanced level, preparation for ЕГЭ/ОГЭ, using specialized terminology.
• Extracurricular: general popular science style for a wide audience.
