Final answer:
Your essay to the mayor on graffiti should be based on the ideas, concepts, and information from the passage set, focusing on the impact of graffiti and using the provided materials to support your argument.
Step-by-step explanation:
In writing a letter to the mayor regarding the maintenance or removal of graffiti in public spaces, your essay should be primarily based on ideas, concepts, and information from the passage set provided. While personal anecdotes and political opinions might provide some context or support your argument, they should not be the foundation of your essay. Scientific experiments, unless directly relevant to the topic of graffiti, are likely less applicable. Instead, focus on the material provided to you, such as the impact of graffiti on communities, official policies, and the cultural significance of street art, to craft a well-reasoned argument that is supportive of the position presented in your materials.
