Modal verbs are a unique subset of English verbs that express necessity, possibility, permission, ability, and obligation. They are often used to modify other verbs, and each has its own nuances and rules for usage. Modal verbs can be complex because their meanings can change based on context, and they don't usually inflect for tense or person. Consider the following examples: 'You should study harder for the exams.' ('Should' implies a recommendation or advice.) 'She can play the piano.' ('Can' reflects ability.) 'Students may not leave the classroom until the bell rings.' ('May' expresses permission or possibility.) Based on your understanding of modal verbs, analyze the role and meaning of two different modal verbs in the sentences provided. Explain how changing the modal verb in each sentence might alter the meaning or appropriateness in a given context.
