Q: While on one hand the Heian period was an unusually long period of peace, it can also be argued that the period weakened Japan economically and led to poverty for all but a tiny few of its inhabitants. The control of rice fields provided a key source of income for families such as the Fujiwara and were a fundamental base for their power. The aristocratic beneficiaries of Heian culture, the Ryōmin (良民 "Good People") numbered about five thousand in a land of perhaps five million. One reason the samurai were able to take power was that the ruling nobility proved incompetent at managing Japan and its provinces. By the year 1000 the government no longer knew how to issue currency and money was gradually disappearing. Instead of a fully realised system of money circulation, rice was the primary unit of exchange. The lack of a solid medium of economic exchange is implicitly illustrated in novels of the time. For instance, messengers were rewarded with useful objects, e.g., an old silk kimono, rather than paid a fee.

A: What crop was a primary source of income during the Heian period?

Q: In 1953, the Republican Party's Old Guard presented Eisenhower with a dilemma by insisting he disavow the Yalta Agreements as beyond the constitutional authority of the Executive Branch; however, the death of Joseph Stalin in March 1953 made the matter a practical moot point. At this time Eisenhower gave his Chance for Peace speech in which he attempted, unsuccessfully, to forestall the nuclear arms race with the Soviet Union by suggesting multiple opportunities presented by peaceful uses of nuclear materials. Biographer Stephen Ambrose opined that this was the best speech of Eisenhower's presidency.

A: What agreements did the GOP Old Guard want Eisenhower to abandon?
