Question

1. which source would be most relevant if researching the history of the public education system in the united states?○ a news article about proposed changes in u.s. education policy○ the local school boards online newsletter○ a wikipedia article about brown vs. board of education○ an interactive timeline of important moments in u.s. public education

Explanation:

The goal is to find a source focused on the history of the entire U.S. public education system. A news article about proposed policy changes covers current, not historical, information. A local school board newsletter only addresses a small, specific area, not national history. A Wikipedia article on Brown vs. Board of Education covers one key historical event, but not the full scope of the system's history. An interactive timeline of important moments in U.S. public education is designed to outline the full historical progression of the national system, making it the most relevant source.

Answer:

an interactive timeline of important moments in U.S. public education
