Problem: Sino-Tibetan relations during the Ming dynasty:

During his travels beginning in 1403, Deshin Shekpa was induced by further exhortations by the Ming court to visit Nanjing by April 10, 1407. Norbu writes that the Yongle Emperor, following the tradition of Mongol emperors and their reverence for the Sakya lamas, showed an enormous amount of deference towards Deshin Shekpa. The Yongle Emperor came out of the palace in Nanjing to greet the Karmapa and did not require him to kowtow like a tributary vassal. According to Karma Thinley, the emperor gave the Karmapa the place of honor at his left, and on a higher throne than his own. Rossabi and others describe a similar arrangement made by Kublai Khan and the Sakya Phagpa lama, writing that Kublai would "sit on a lower platform than the Tibetan cleric" when receiving religious instructions from him.

When did Deshin Shekpa travels start?

A: 1403


Problem: In the late 1960s, the term heavy metal was used interchangeably with hard rock, but gradually began to be used to describe music played with even more volume and intensity. While hard rock maintained a bluesy rock and roll identity, including some swing in the back beat and riffs that tended to outline chord progressions in their hooks, heavy metal's riffs often functioned as stand-alone melodies and had no swing in them. Heavy metal took on "darker" characteristics after Black Sabbath's breakthrough at the beginning of the 1970s. In the 1980s it developed a number of subgenres, often termed extreme metal, some of which were influenced by hardcore punk, and which further differentiated the two styles. Despite this differentiation, hard rock and heavy metal have existed side by side, with bands frequently standing on the boundary of, or crossing between, the genres.
What band had a 1960s break through with an emphasis on darker themes?

On July 22, 2008, in the aftermath of the Southwest Airlines inspection scandal, a bill was unanimously approved in the House to tighten regulations concerning airplane maintenance procedures, including the establishment of a whistleblower office and a two-year "cooling off" period that FAA inspectors or supervisors of inspectors must wait before they can work for those they regulated. The bill also required rotation of principal maintenance inspectors and stipulated that the word "customer" properly applies to the flying public, not those entities regulated by the FAA. The bill died in a Senate committee that year.
how long was the "cooling off" period that the FAA inspectors or supervisers of inspectors must wait before they can work for those they regulate?
A: two-year

Question: In 1899 the state legislature passed a new constitution, with requirements for poll taxes and literacy tests for voter registration which disfranchised most black Americans in the state. Exclusion from voting had wide effects: it meant that black Americans could not serve on juries or in any local office. After a decade of white supremacy, many people forgot that North Carolina had ever had thriving middle-class black Americans. Black citizens had no political voice in the state until after the federal Civil Rights Act of 1964 and Voting Rights Act of 1965 were passed to enforce their constitutional rights. It was not until 1992 that another African American was elected as a US Representative from North Carolina.
Is there an answer to this question: Being excluded from doing what, made it so that black people could not serve on juries or in public office?

Answer: voting

In the United States, federal government policy promotes the use of racially categorized data to identify and address health disparities between racial or ethnic groups. In clinical settings, race has sometimes been considered in the diagnosis and treatment of medical conditions. Doctors have noted that some medical conditions are more prevalent in certain racial or ethnic groups than in others, without being sure of the cause of those differences. Recent interest in race-based medicine, or race-targeted pharmacogenomics, has been fueled by the proliferation of human genetic data which followed the decoding of the human genome in the first decade of the twenty-first century. There is an active debate among biomedical researchers about the meaning and importance of race in their research. Proponents of the use of racial categories in biomedicine argue that continued use of racial categorizations in biomedical research and clinical practice makes possible the application of new genetic findings, and provides a clue to diagnosis.
What do proponents of the use of racial categories in biomedicine think it makes possible?
A:
application of new genetic findings,
