Answer:
C. an attempt to overthrow communist rule in Hungary
Explanation:
The Hungarian flag was bearing the Rakosi coat of arms, reflecting the communist rule in Hungary. The Hungarians though despised the Soviets and being under their control, so they made a revolution. The Hungarian Revolution had its own flag, and the flag was totally the same, apart from the Rakosi coat of arms being cut off from it, thus having a white gap in he center. The meaning of this feature on the flag was that the Hungarians want to overthrow the communist rule in the country, and that the communism and the Soviet rule doesn't have place in their society.
<u> B. It gives specific powers to the federal government.</u>
The United States Constitution grants specific powers and rights to the federal government, called "delegated powers", if it is not outlined in it, then the government should not do it. Furthermore, the Tenth Amendment establishes that all powers that aren't listed in the Constitution are granted to the people or the states. This way, it prevents conflict between federal and state government, and also prevents the government from abusing of its power.
The first one is the correct answer because if the sign if somethings goes from negative to a positive or positive to a negative, everything in the equation switches.
