The problem: Answer a question about this article:
St. Barthélemy has a small airport known as Gustaf III Airport on the north coast of the island that is served by small regional commercial aircraft and charters. The nearest airport with a runway length sufficient to land a typical commercial jet airliner is on the neighboring island of Sint Maarten: Princess Juliana International Airport, which acts as a hub, providing connecting flights with regional carriers to St. Barthélemy. Several international airlines and domestic Caribbean airlines operate in this sector.
Where is the airport located on the island?
****
The answer: the north coast


Problem: Please answer a question about the following article about Protestantism:
In the course of this religious upheaval, the German Peasants' War of 1524–25 swept through the Bavarian, Thuringian and Swabian principalities. After the Eighty Years' War in the Low Countries and the French Wars of Religion, the confessional division of the states of the Holy Roman Empire eventually erupted in the Thirty Years' War between 1618 and 1648. It devastated much of Germany, killing between 25% and 40% of its population. The main tenets of the Peace of Westphalia, which ended the Thirty Years' War, were:
What war was waged from 1618 to 1648?
A: the Thirty Years' War


Question: Read this and answer the question

Van Praag states that the Ming court established diplomatic delegations with Tibet merely to secure urgently needed horses. Wang and Nyima argue that these were not diplomatic delegations at all, that Tibetan areas were ruled by the Ming since Tibetan leaders were granted positions as Ming officials, that horses were collected from Tibet as a mandatory "corvée" tax, and therefore Tibetans were "undertaking domestic affairs, not foreign diplomacy". Sperling writes that the Ming simultaneously bought horses in the Kham region while fighting Tibetan tribes in Amdo and receiving Tibetan embassies in Nanjing. He also argues that the embassies of Tibetan lamas visiting the Ming court were for the most part efforts to promote commercial transactions between the lamas' large, wealthy entourage and Ming Chinese merchants and officials. Kolmaš writes that while the Ming maintained a laissez-faire policy towards Tibet and limited the numbers of the Tibetan retinues, the Tibetans sought to maintain a tributary relationship with the Ming because imperial patronage provided them with wealth and power. Laird writes that Tibetans eagerly sought Ming court invitations since the gifts the Tibetans received for bringing tribute were much greater in value than the latter. As for the Yongle Emperor's gifts to his Tibetan and Nepalese vassals such as silver wares, Buddha relics, utensils for Buddhist temples and religious ceremonies, and gowns and robes for monks, Tsai writes "in his effort to draw neighboring states to the Ming orbit so that he could bask in glory, the Yongle Emperor was quite willing to pay a small price". The Information Office of the State Council of the PRC lists the Tibetan tribute items as oxen, horses, camels, sheep, fur products, medical herbs, Tibetan incenses, thangkas (painted scrolls), and handicrafts; while the Ming awarded Tibetan tribute-bearers an equal value of gold, silver, satin and brocade, bolts of cloth, grains, and tea leaves. Silk workshops during the Ming also catered specifically to the Tibetan market with silk clothes and furnishings featuring Tibetan Buddhist iconography.

Why does Van Praag believe the Ming court set up a diplomatic delegation with Tibet?
Answer: to secure urgently needed horses


Problem: During childhood, siblings are a source of conflict and frustration as well as a support system. Adolescence may affect this relationship differently, depending on sibling gender. In same-sex sibling pairs, intimacy increases during early adolescence, then remains stable. Mixed-sex siblings pairs act differently; siblings drift apart during early adolescent years, but experience an increase in intimacy starting at middle adolescence. Sibling interactions are children's first relational experiences, the ones that shape their social and self-understanding for life. Sustaining positive sibling relations can assist adolescents in a number of ways. Siblings are able to act as peers, and may increase one another's sociability and feelings of self-worth. Older siblings can give guidance to younger siblings, although the impact of this can be either positive or negative depending on the activity of the older sibling.
At what stage to mixed-sex siblings generally experience an increase in intimacy?
The answer is the following: middle adolescence


The deliberate or accidental hybridising of two or more species of closely related animals through captive breeding is a human activity which has been in existence for millennia and has grown in recent times for economic purposes. The number of successful interspecific mammalian hybrids is relatively small, although it has come to be known that there is a significant number of naturally occurring hybrids between forms or regional varieties of a single species.[citation needed] These may form zones of gradation known as clines. Indeed, the distinction between some hitherto distinct species can become clouded once it can be shown that they may not only breed but produce fertile offspring. Some hybrid animals exhibit greater strength and resilience than either parent. This is known as hybrid vigor. The existence of the mule (donkey sire; horse dam) being used widely as a hardy draught animal throughout ancient and modern history is testament to this. Other well known examples are the lion/tiger hybrid, the liger, which is by far the largest big cat and sometimes used in circuses; and cattle hybrids such as between European and Indian domestic cattle or between domestic cattle and American bison, which are used in the meat industry and marketed as Beefalo. There is some speculation that the donkey itself may be the result of an ancient hybridisation between two wild ass species or sub-species. Hybrid animals are normally infertile partly because their parents usually have slightly different numbers of chromosomes, resulting in unpaired chromosomes in their cells, which prevents division of sex cells and the gonads from operating correctly, particularly in males. There are exceptions to this rule, especially if the speciation process was relatively recent or incomplete as is the case with many cattle and dog species. Normally behavior traits, natural hostility, natural ranges and breeding cycle differences maintain the separateness of closely related species and prevent natural hybridisation. However, the widespread disturbances to natural animal behaviours and range caused by human activity, cities, dumping grounds with food, agriculture, fencing, roads and so on do force animals together which would not normally breed. Clear examples exist between the various sub-species of grey wolf, coyote and domestic dog in North America. As many birds and mammals imprint on their mother and immediate family from infancy, a practice used by animal hybridizers is to foster a planned parent in a hybridization program with the same species as the one with which they are planned to mate.
What is the name given when zones of gradation exits?
clines


Here is a question about this article: At Princeton, the physicist Robert R. Wilson encouraged Feynman to participate in the Manhattan Project—the wartime U.S. Army project at Los Alamos developing the atomic bomb. Feynman said he was persuaded to join this effort to build it before Nazi Germany developed their own bomb. He was assigned to Hans Bethe's theoretical division and impressed Bethe enough to be made a group leader. He and Bethe developed the Bethe–Feynman formula for calculating the yield of a fission bomb, which built upon previous work by Robert Serber.
What is the answer to this question: What did Feynman produce with the help of Bethe?
****
So...
Bethe–Feynman formula
