Problem: Heian period:

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 Ryomin ( "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.

Currency gradually disappeared around what year?

A: 1000

Problem: The Bronx has also become home to a peculiar poetic tribute, in the form of the Heinrich Heine Memorial, better known as the Lorelei Fountain from one of Heine's best-known works (1838). After Heine's German birthplace of Dusseldorf had rejected, allegedly for anti-Semitic motives, a centennial monument to the radical German-Jewish poet (17971856), his incensed German-American admirers, including Carl Schurz, started a movement to place one instead in Midtown Manhattan, at Fifth Avenue and 59th Street. However, this intention was thwarted by a combination of ethnic antagonism, aesthetic controversy and political struggles over the institutional control of public art.
When was Heine born?

Context and question: By 1957, pan-Arabism was the dominant ideology of the Arab world, and the average Arab citizen considered Nasser his undisputed leader. Historian Adeed Dawisha credited Nasser's status to his "charisma, bolstered by his perceived victory in the Suez Crisis". The Cairo-based Voice of the Arabs radio station spread Nasser's ideas of united Arab action throughout the Arabic-speaking world and historian Eugene Rogan wrote, "Nasser conquered the Arab world by radio." Lebanese sympathizers of Nasser and the Egyptian embassy in Beirutthe press center of the Arab worldbought out Lebanese media outlets to further disseminate Nasser's ideals. Nasser also enjoyed the support of Arab nationalist organizations, both civilian and paramilitary, throughout the region. His followers were numerous and well-funded, but lacked any permanent structure and organization. They called themselves "Nasserites", despite Nasser's objection to the label (he preferred the term "Arab nationalists").
What did the admirers of Nasser lack?
Answer: structure and organization
