Answer:
Step-by-step explanation:
Your argument is People should attain the legal rights of adulthood at the age of 18 because that’s when our minds can start developing, especially with more responsibilities and new experiences.
Rebuttal to your argument and support the original argument of People should attain the legal rights of adulthood at the age of 21 or up because they have become mature, physically, and mentally strong:
At the age of 18, the mind just starts developing. With more responsibilities and new experiences, it can be overwhelming and be influenced by others. If the mind is allowed to further develop and become more mature at age of 21, it will be able to better handle the responsibilities and rights of adulthood.
