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 "corvee" 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. Kolmas 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.

who were the Tibetan areas were ruled by?
Answer: the Ming

Problem: In ultra high vacuum systems, some very "odd" leakage paths and outgassing sources must be considered. The water absorption of aluminium and palladium becomes an unacceptable source of outgassing, and even the adsorptivity of hard metals such as stainless steel or titanium must be considered. Some oils and greases will boil off in extreme vacuums. The permeability of the metallic chamber walls may have to be considered, and the grain direction of the metallic flanges should be parallel to the flange face.
What can boil away in extreme vaccum exposure?
The answer is the following: Some oils and greases

In 1348, the Black Death and other disasters sealed a sudden end to the previous period of massive philosophic and scientific development. Yet, the rediscovery of ancient texts was improved after the Fall of Constantinople in 1453, when many Byzantine scholars had to seek refuge in the West. Meanwhile, the introduction of printing was to have great effect on European society. The facilitated dissemination of the printed word democratized learning and allowed a faster propagation of new ideas. New ideas also helped to influence the development of European science at this point: not least the introduction of Algebra. These developments paved the way for the Scientific Revolution, which may also be understood as a resumption of the process of scientific inquiry, halted at the start of the Black Death.
What caused ancient texts to be rediscovered by Byzantine scholars?
the Fall of Constantinople in 1453

Input: Portugal
During the century of internecine struggles for dominance among the Northern Christians kingdoms, the County of Portugal, formed the southern portion of the Kingdom of Galicia. At times the Kingdom of Galicia existed independently for short periods, but usually formed an important part of the Kingdom of Leon. Throughout this period, the people of County of Portugal as Galicians found themselves struggling to maintain the autonomy of Galicia with its distinct language and culture (Galician-Portuguese) from the Leonese culture, whenever the status of the Kingdom of Galicia changed in relation to the Kingdom of Leon. As a result of political division, Galician-Portuguese lost its unity when the County of Portugal separated from the Kingdom of Galicia (a dependent kingdom of Leon) to establish the Kingdom of Portugal. The Galician and Portuguese versions of the language then diverged over time as they followed independent evolutionary paths. This began occurring when the Kingdom of Leon and the Kingdom of Castile united and the Castilian Language (known as Spanish) slowly over the centuries began influencing the Galician Language and then trying to replace it. The same thing happened to Astur-Leonese Language to the point where it is greatly reduced or completely replaced by the Castilian (Spanish Language).

The County of Portugal separated from the Kingdom of Galicia to establish what?
Output: the Kingdom of Portugal

Problem: Please answer a question about the following article about God:
The gender of God may be viewed as either a literal or an allegorical aspect of a deity who, in classical western philosophy, transcends bodily form. Polytheistic religions commonly attribute to each of the gods a gender, allowing each to interact with any of the others, and perhaps with humans, sexually. In most monotheistic religions, God has no counterpart with which to relate sexually. Thus, in classical western philosophy the gender of this one-and-only deity is most likely to be an analogical statement of how humans and God address, and relate to, each other. Namely, God is seen as begetter of the world and revelation which corresponds to the active (as opposed to the receptive) role in sexual intercourse.
How is sex by God handled in a monotheistic religion?
A:
God has no counterpart with which to relate sexually
