Problem: Orientation behaviour studies have been traditionally carried out using variants of a setup known as the Emlen funnel, which consists of a circular cage with the top covered by glass or wire-screen so that either the sky is visible or the setup is placed in a planetarium or with other controls on environmental cues. The orientation behaviour of the bird inside the cage is studied quantitatively using the distribution of marks that the bird leaves on the walls of the cage. Other approaches used in pigeon homing studies make use of the direction in which the bird vanishes on the horizon.
How are orientation behavior studies traditionally carried out?
The answer is the following: the Emlen funnel

For the anthropologists Lieberman and Jackson (1995), however, there are more profound methodological and conceptual problems with using cladistics to support concepts of race. They claim that "the molecular and biochemical proponents of this model explicitly use racial categories in their initial grouping of samples". For example, the large and highly diverse macroethnic groups of East Indians, North Africans, and Europeans are presumptively grouped as Caucasians prior to the analysis of their DNA variation. This is claimed to limit and skew interpretations, obscure other lineage relationships, deemphasize the impact of more immediate clinal environmental factors on genomic diversity, and can cloud our understanding of the true patterns of affinity. They argue that however significant the empirical research, these studies use the term race in conceptually imprecise and careless ways. They suggest that the authors of these studies find support for racial distinctions only because they began by assuming the validity of race. "For empirical reasons we prefer to place emphasis on clinal variation, which recognizes the existence of adaptive human hereditary variation and simultaneously stresses that such variation is not found in packages that can be labeled races."
What is variation found in that can be labeled as races?
packages

Input: Classical music
Given the wide range of styles in classical music, from Medieval plainchant sung by monks to Classical and Romantic symphonies for orchestra from the 1700s and 1800s to avant-garde atonal compositions for solo piano from the 1900s, it is difficult to list characteristics that can be attributed to all works of that type. However, there are characteristics that classical music contains that few or no other genres of music contain, such as the use of a printed score and the performance of very complex instrumental works (e.g., the fugue). As well, although the symphony did not exist through the entire classical music period, from the mid-1700s to the 2000s the symphony ensembleand the works written for ithave become a defining feature of classical music.

Who sang medieval plainchant?
Output: monks

Input: Article: In Iberia, the Christian states, which had been confined to the north-western part of the peninsula, began to push back against the Islamic states in the south, a period known as the Reconquista. By about 1150, the Christian north had coalesced into the five major kingdoms of Leon, Castile, Aragon, Navarre, and Portugal. Southern Iberia remained under control of Islamic states, initially under the Caliphate of Cordoba, which broke up in 1031 into a shifting number of petty states known as taifas, who fought with the Christians until the Almohad Caliphate re-established centralised rule over Southern Iberia in the 1170s. Christian forces advanced again in the early 13th century, culminating in the capture of Seville in 1248.

Now answer this question: What Islamic state controlled southern Iberia in the 1170s?

Output: the Almohad Caliphate

Article: For the remainder of the Korean War the UN Command and the PVA fought, but exchanged little territory; the stalemate held. Large-scale bombing of North Korea continued, and protracted armistice negotiations began 10 July 1951 at Kaesong. On the Chinese side, Zhou Enlai directed peace talks, and Li Kenong and Qiao Guanghua headed the negotiation team. Combat continued while the belligerents negotiated; the UN Command forces' goal was to recapture all of South Korea and to avoid losing territory. The PVA and the KPA attempted similar operations, and later effected military and psychological operations in order to test the UN Command's resolve to continue the war.

Question: Where did armistice negotiations occur?
Ans: Kaesong

Marine mammals are many, such as the dolphins, porpoises and whales, which are seen here during the migration period from December till May. Turtles are a common sight along the coastline of the island. They are a protected species and in the endangered list. It is stated that it will take 1550 years for this species to attain reproductive age. Though they live in the sea, the females come to the shore to lay eggs and are protected by private societies. Three species of turtles are particularly notable. These are: The leatherback sea turtles which have leather skin instead of a shell and are the largest of the type found here, some times measuring a much as 3 m (average is about 1.5 m) and weighing about 450 kg (jellyfish is their favourite diet); the hawksbill turtles, which have hawk-like beaks and found near reefs, generally about 90 cm in diameter and weigh about 60 kg and their diet consists of crabs and snails; and the green turtles, herbivores which have rounded heads, generally about 90 cm in diameter and live amidst tall sea grasses.

What is the favorite prey of leatherback sea turtles?
Output:
jellyfish
