Diary and artifact.
Primary Sources come from the original time or event. A diary represents a first-hand account of something by the original person. An artifact does virtually the same thing, being from that time period. All the other choices are incorrect because they are often told in a way that changes the original story or event.
Economic reforms introducing market principles began in 1978 and were carried out in two stages. The first stage, in the late 1970s and early 1980s, involved the decollectivization of agriculture, the opening up of the country to foreign investment, and permission for entrepreneurs to start businesses.
Hitler pledged to restore prosperity, create civil order (by crushing industrial strikes and street demonstrations by communists and socialists), eliminate the influence of Jewish financiers, and make the fatherland once again a world power.
The Truman Doctrine definitely represents the policy of containment. Containment is the idea that America wants to stop the spread of communism to other nations. America is fearful that if they fail to stop communism from spreading to one country, that it will lead to several countries becoming communist (known as the domino effect).
In order to stop the spread of communism, the US government tries to give financial assistance to countries that are susceptible to falling under Soviet control. Two of these countries in particular are Turkey and Greece (due to their geographical location near the Soviet Union). This is why President Harry Truman proposes $400 million worth of aid to these countries, so that they may stabilize their economy and become allies with the United States. This shows containment, as without these funds the countries could have very well been taken over by the Soviet Union and the system of communism.
