The Importance of Proper Grammar in Communication** **

** Proper grammar is essential for effective communication. It ensures that the message is clear and understood correctly by the audience. In the sentence "Andrea __ the piano very well," the correct option is "doesn't playb). This choice adheres to the rules of subject-verb agreement and maintains the negative form required by the context. Using incorrect grammar can lead to misunderstandings and misinterpretations. For instance, if we were to use "don't plays" or "doesn't plays," it would violate the subject-verb agreement rules, making the sentence grammatically incorrect. Therefore, it is crucial to use "doesn't play" to convey the intended meaning accurately. In conclusion, proper grammar not only enhances the clarity of communication but also reflects the speaker's credibility and command over the language. Hence, mastering grammar is a vital skill for effective and precise expression.
