Please answer this: Question: "Why might a bird preen in front of another one?" Context: "Birds sometimes use plumage to assess and assert social dominance, to display breeding condition in sexually selected species, or to make threatening displays, as in the sunbittern's mimicry of a large predator to ward off hawks and protect young chicks. Variation in plumage also allows for the identification of birds, particularly between species. Visual communication among birds may also involve ritualised displays, which have developed from non-signalling actions such as preening, the adjustments of feather position, pecking, or other behaviour. These displays may signal aggression or submission or may contribute to the formation of pair-bonds. The most elaborate displays occur during courtship, where "dances" are often formed from complex combinations of many possible component movements; males' breeding success may depend on the quality of such displays."

Answer: Visual communication among birds

Please answer this: Question: "Who were his intimates who shared his interests directly?" Context: "Four boarders at his parents' apartments became Chopin's intimates: Tytus Woyciechowski, Jan Nepomucen Biaobocki, Jan Matuszynski and Julian Fontana; the latter two would become part of his Paris milieu. He was friendly with members of Warsaw's young artistic and intellectual world, including Fontana, Jozef Bohdan Zaleski and Stefan Witwicki. He was also attracted to the singing student Konstancja Gadkowska. In letters to Woyciechowski, he indicated which of his works, and even which of their passages, were influenced by his fascination with her; his letter of 15 May 1830 revealed that the slow movement (Larghetto) of his Piano Concerto No. 1 (in E minor) was secretly dedicated to her "It should be like dreaming in beautiful springtime by moonlight." His final Conservatory report (July 1829) read: "Chopin F., third-year student, exceptional talent, musical genius."" Answer:
++++++++
Answer: Fontana, Jozef Bohdan Zaleski and Stefan Witwicki

Please answer this: Question: "The term Far East grew out of what?" Context: "In the 20th century after decades of intense warfare and political turmoil terms such as "Near East", "Far East" and "Middle East" were relegated to the experts, especially in the new field of political science. The new wave of diplomats often came from those programs. Archaeology on the international scene, although very much of intellectual interest to the major universities, fell into the shadow of international relations. Their domain became the Ancient Near East, which could no longer be relied upon to be the Near East. The Ottoman Empire was gone, along with all the other empires of the 19th century, replaced with independent republics. Someone had to reconcile the present with the past. This duty was inherited by various specialized agencies that were formed to handle specific aspects of international relations, now so complex as to be beyond the scope and abilities of a diplomatic corps in the former sense. The ancient Near East is frozen in time. The living Near East is primarily what the agencies say it is. In most cases this single term is inadequate to describe the geographical range of their operations. The result is multiple definitions." Answer:
++++++++
Answer:
intense warfare and political turmoil
