Problem: Tibet:

Tibet has various festivals that are commonly performed to worship the Buddha[citation needed] throughout the year. Losar is the Tibetan New Year Festival. Preparations for the festive event are manifested by special offerings to family shrine deities, painted doors with religious symbols, and other painstaking jobs done to prepare for the event. Tibetans eat Guthuk (barley noodle soup with filling) on New Year's Eve with their families. The Monlam Prayer Festival follows it in the first month of the Tibetan calendar, falling between the fourth and the eleventh days of the first Tibetan month. It involves dancing and participating in sports events, as well as sharing picnics. The event was established in 1049 by Tsong Khapa, the founder of the Dalai Lama and the Panchen Lama's order.

Problem: The head is enclosed in a hard, heavily sclerotized, unsegmented, exoskeletal head capsule, or epicranium, which contains most of the sensing organs, including the antennae, ocellus or eyes, and the mouthparts. Of all the insect orders, Orthoptera displays the most features found in other insects, including the sutures and sclerites. Here, the vertex, or the apex (dorsal region), is situated between the compound eyes for insects with a hypognathous and opisthognathous head. In prognathous insects, the vertex is not found between the compound eyes, but rather, where the ocelli are normally. This is because the primary axis of the head is rotated 90 to become parallel to the primary axis of the body. In some species, this region is modified and assumes a different name.:13
What is the vertex also known as?

Burke believed that property was essential to human life. Because of his conviction that people desire to be ruled and controlled, the division of property formed the basis for social structure, helping develop control within a property-based hierarchy. He viewed the social changes brought on by property as the natural order of events, which should be taking place as the human race progressed. With the division of property and the class system, he also believed that it kept the monarch in check to the needs of the classes beneath the monarch. Since property largely aligned or defined divisions of social class, class too, was seen as naturalpart of a social agreement that the setting of persons into different classes, is the mutual benefit of all subjects. Concern for property is not Burke's only influence. As Christopher Hitchens summarises, "If modern conservatism can be held to derive from Burke, it is not just because he appealed to property owners in behalf of stability but also because he appealed to an everyday interest in the preservation of the ancestral and the immemorial."
What did Burke believe was against the natural order of events?

Context and question: In the Age of Reason philosophical tracts and speculations on history and human nature integrated literature with social and political developments. The inevitable reaction was the explosion of Romanticism in the later 18th century which reclaimed the imaginative and fantastical bias of old romances and folk-literature and asserted the primacy of individual experience and emotion. But as the 19th-century went on, European fiction evolved towards realism and naturalism, the meticulous documentation of real life and social trends. Much of the output of naturalism was implicitly polemical, and influenced social and political change, but 20th century fiction and drama moved back towards the subjective, emphasising unconscious motivations and social and environmental pressures on the individual. Writers such as Proust, Eliot, Joyce, Kafka and Pirandello exemplify the trend of documenting internal rather than external realities.
What effect did 20th century fiction and tragedy have on the world?
Answer: unanswerable
