Example Input: From 1974 (the creation of the British colony of Tuvalu) until independence, the legislative body of Tuvalu was called the House of the Assembly or Fale I Fono. Following independence in October 1978 the House of the Assembly was renamed the Parliament of Tuvalu or Palamene o Tuvalu. The unicameral Parliament has 15 members with elections held every four years. The members of parliament select the Prime Minister (who is the head of government) and the Speaker of Parliament. The ministers that form the Cabinet are appointed by the Governor General on the advice of the Prime Minister.
Example Output: When did Tuvalu acquire independence?

Example Input: 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.
Example Output: What crop was a primary source of income during the Heian period?
