Answer:
Mexico is a federal presidential representative democratic republic wherein the President is both the head of state and head of government
Explanation:
First off, the controversy of this had led to an imbalance in congress among the number of free states and slave states. So this rules out our first option. Due to it not being all of the above, that's our fourth answer ruled out as well. The Webster speech did not happen for 10 more years so it is very unlikely that this is what led to that speech. Even without the process of elimination, it would be B because the Missouri Compromise admitted Missouri as a slave state and Maine as a free state in order to preserve the balance of power in congress. Also, Henry Clay (the Great Compromiser) drafted this.
Oh now i get it.
Well the answer should be in a general election, each state has officials who count and CERTIFY votes.
The officials have to make sure that the people who give their vote have the credibility and rights to voice their vote, to avoid any sort of Election fraud that may negatively effect one candidate.
