Justinian I.
Explanation:
The Roman have had their own unique set of laws that they implement on all new territories that they have conquered. Everyone had to obey these laws and respect them. The problem was that as the society was becoming more and more developed the Roman laws started to gradually lose sense or to be badly formatted for the changed circumstances, thus creating lot of confusion.
Justinian I decided to change this. He took the Roman laws, sorted them out properly and in accordance to the needs of the people and the state. He then changed some and also implemented some new ones. All in all, Justinian managed to create a better organized, more developed, practical, and modern set of laws. He created the Justinian Code.
Answer: B. US troops would gradually withdraw from Vietnam.
Context/detail:
Richard Nixon came into office as President in January, 1969. By that time the war in Vietnam involved hundreds of thousands of American troops and over 30,000 American lives had already been lost in the war. The war had become increasingly unpopular with the American people. In November, 1969, President Nixon gave a speech which announced his Vietnamization policy, which emphasized that the United States must empower South Vietnamese forces to assume more combat duties.
By the time the US was shifting emphasis to this sort of policy, it was too late to stave off the victory of the North Vietnamese and Viet Cong forces. The US eventually withdrew its forces from Vietnam in 1973, and by 1975, Saigon (in South Vietnam) fell to the North Vietnamese communist forces.
