Perry approached Japan in a somewhat threatening manner. He sought after them with a navy vessel at his side and basically told them to open their trade relations or else. =)
The correct answers are:
Buddhism
While this philosophical and spiritual doctrine originated in what today is India and Nepal, it spread largely through China around the 6th century AD. From China, it entered in Korea where it became the main religion and developed its own interpretation and variants.
Confucianism
Confucianism is a set of moral doctrines that emerged in China following the teachings of Kung-Fu-Tzu (Confucius) around the 6th century BCE. This philosophy shaped strongly the social and political life of China and other Eastern Asian peoples, like Korea.
Movable type
The Movable type is a printing technology, and the first known technology of this kind was invented in China in the 11th century AD by the Chinese inventor Bi Sheng. From China, this technology entered in Korea and during the 13th century the Koryo dynasty invented a metallic movable type.
Celadon pottery
Celadon is a kind of ceramic originally from China. Celadon pottery entered into Korea from China and it became very popular and an important cultural feature of this country. Korean celadon pottery was very extended mainly during the 10th and 11th centuries under the Goryeo dynasty, that produced the Goreyo pottery also known as classic Korean ceramic.
C) Reestablished controls on prices, wages, and rents.
In 1946, a joint resolution of Congress extended the price controls enacted during World War II for an extra year past their initially planned end date, in order to help as the country transitioned to a peacetime economy. The government wanted to get away from price controls, but didn't want to do so too abruptly. The joint resolution (passed in July, 1946), included this statement: "It is hereby declared to be the policy of the Congress that the Office of Price Administration, and other agencies of the Government, shall use their price, subsidy, and other powers to promote the earliest practicable balance between production and the demand therefor of commodities under their control, and that the general control of prices and the use of subsidy powers shall, subject to other specific provisions of this Act, be terminated as rapidly as possible consistent with the policies and purposes set forth in this section and in no event later than June 30, 1947, and on that date the Office of Price Administration shall be abolished.
"
So there was a temporary extension of the price control measures, reestablished or extended by the joint resolution of Congress.
