The transition from hunting and gathering to agriculture is not necessarily a one way process. It has been argued that hunting and gathering represents an adaptive strategy, which may still be exploited, if necessary, when environmental change causes extreme food stress for agriculturalists. In fact, it is sometimes difficult to draw a clear line between agricultural and hunter-gatherer societies, especially since the widespread adoption of agriculture and resulting cultural diffusion that has occurred in the last 10,000 years.[citation needed] This anthropological view has remained unchanged since the 1960s.[clarification needed][citation needed]
What situation can cause food stresses that make hunting-gathering necessary?
environmental change


Input: Greece
Meanwhile, Andreas Papandreou founded the Panhellenic Socialist Movement (PASOK) in response to Karamanlis's conservative New Democracy party, with the two political formations alternating in government ever since. Greece rejoined NATO in 1980. Greece became the tenth member of the European Communities (subsequently subsumed by the European Union) on 1 January 1981, ushering in a period of sustained growth. Widespread investments in industrial enterprises and heavy infrastructure, as well as funds from the European Union and growing revenues from tourism, shipping and a fast-growing service sector raised the country's standard of living to unprecedented levels. Traditionally strained relations with neighbouring Turkey improved when successive earthquakes hit both nations in 1999, leading to the lifting of the Greek veto against Turkey's bid for EU membership.

In what year did Greece rejoin NATO?
Output: 1980


Input: Article: From early 1944 until the days leading up to the invasion, Kuribayashi transformed the island into a massive network of bunkers, hidden guns, and 11 mi (18 km) of underground tunnels. The heavy American naval and air bombardment did little but drive the Japanese further underground, making their positions impervious to enemy fire. Their pillboxes and bunkers were all connected so that if one was knocked out, it could be reoccupied again. The network of bunkers and pillboxes greatly favored the defender.

Now answer this question: Who transformed the island into a fortress?

Output: Kuribayashi


Article: When World War II started in 1939, it divided the world into two alliances—the Allies (the United Kingdom and France at first in Europe, China in Asia since 1937, followed in 1941 by the Soviet Union, the United States); and the Axis powers consisting of Germany, Italy and Japan.[nb 1] During World War II, the United States, United Kingdom, and Soviet Union controlled Allied policy and emerged as the "Big Three". The Republic of China and the Big Three were referred as a "trusteeship of the powerful"  and were recognized as the Allied "Big Four" in Declaration by United Nations in 1942. These four countries were referred as the "Four Policemen" of the Allies and considered as the primary victors of World War II. The importance of France was acknowledged by their inclusion, along with the other four, in the group of countries allotted permanent seats in the United Nations Security Council.

Question: Who made up the Axis powers?
Ans: Germany, Italy and Japan


Here is a question about this article: A band of Middle Devonian limestone runs west to east from Cremyll to Plymstock including the Hoe. Local limestone may be seen in numerous buildings, walls and pavements throughout Plymouth. To the north and north east of the city is the granite mass of Dartmoor; the granite was mined and exported via Plymouth. Rocks brought down the Tamar from Dartmoor include ores containing tin, copper, tungsten, lead and other minerals. There is evidence that the middle Devonian limestone belt at the south edge of Plymouth and in Plymstock was quarried at West Hoe, Cattedown and Radford.
What is the answer to this question: What river was used to ferry granite from Dartmoor to Plymouth?
****
So... Tamar


Article: New Haven has a long tradition of urban planning and a purposeful design for the city's layout. The city could be argued to have some of the first preconceived layouts in the country. Upon founding, New Haven was laid out in a grid plan of nine square blocks; the central square was left open, in the tradition of many New England towns, as the city green (a commons area). The city also instituted the first public tree planting program in America. As in other cities, many of the elms that gave New Haven the nickname "Elm City" perished in the mid-20th century due to Dutch Elm disease, although many have since been replanted. The New Haven Green is currently home to three separate historic churches which speak to the original theocratic nature of the city. The Green remains the social center of the city today. It was named a National Historic Landmark in 1970.

Question: On what type of city plan was New Haven laid out upon the founding of the area?
Ans:
grid plan of nine square blocks
