Although there is no one person in charge in commission-style city governments, there is one commissioner elected as or to preside over meetings.
A. leader... governor
B. mayor... chairmen
G. president...chairman
D. director...executor

The correct answer is B. Mayor or chairman.

Explanation:

City commission governments are types of political organization in local governments, through which there is no single person in command of the executive power of the city (the typical mayor) but rather this position is exercised jointly and shared by a group of people, usually 7, who decide the political and economic direction of the city through voting. Of these 7 members, however, one of them is usually determined as the greatest or the chairman, but only for representative purposes, since he does not have greater decision-making power than the rest of the members of the commission.

after the civil war, and with the termination of slavery, the south was faced with a big problem; what was supposed to happen and how they were supposed to deal with the freedom and the rights that black people and freed slaves had gained as a result of the north defeating the south and forcing the end of slavery. first, most, if not all, of the workforce of the south came from slaves and they did not have an option to replace the loss of said workforce. second, particularly in the south, people were convinced that black people were lesser, less intelligent, less capable and less smart than whites. this posed a huge problem for them. also, southerners were faced with another issue; freed slaves now had a say in how their lives would be lived and the right to politically choose the way they would be governed. people in the south did not want to accept this, none of this and this opposition and the conflicts that arose from it, not to mention the afereffects of the war, forced the congress of the time to enact and enforce the reconstruction plans that had been proposed by president andrew johnson.
