This was Horace Mann. He helped create and design the first educational system in the United States, he was the Massachusetts' Secretary of the Board of Education and he started the "Mann's Six Principles", which were his thoughts of how he would choose decisions. He did a lot for schooling and shaped it how it really is today.
Letter B is wrong I took the unit test on E-2020 the correct answer to the question is A.
The congress are voted for by the people. If someone wants to run for Congress, they run against other people. The people choose who they want, and vote for them when the time comes.
Hope it helps ❤️
