<em>A. Congress was denied power to regulate trade.</em>
Explanation:
The Articles of Confederation had many weaknesses, it did not give proper power to the national government, so they could not regulate trade, enforce laws, or tax citizens. Colonists were scared that if enough power got into the hands of the government, the same thing would happen with what happened with Great Britain. Although the national government had no judicial branch, would also be correct in this case, as the national government did not have enough power or resources to do so, the question states "mercantile laws", which have to do with trade. Congress did not have any power to regulate trade under the Articles of Confederation, as they hated how the British used to enforce laws on them about what they can and cannot trade, and who they can and cannot trade with.
Military and diplomatic tensions diminished between 1972 and 1980 as the two superpowers engaged in dialogue, frecuent contacts and agreed to reduce their nuclear stockpiles (SALT Treaty) and to boost bilateral trade. US president Richard Nixon and Soviet secretary-general Leonid Brezhnev met at three summits between 1972 and 1974.
It's a one party system because they got rid of all the other parties and they get full rain of the country and get to do whatever they want. Also fascists believe that great nations show their greatness by conquering and ruling other weak nations. Fascists think the state can survive only if it successfully proves its military superiority in war.
