Here is a question about this article: Historians trace the earliest Baptist church back to 1609 in Amsterdam, with John Smyth as its pastor. Three years earlier, while a Fellow of Christ's College, Cambridge, he had broken his ties with the Church of England. Reared in the Church of England, he became "Puritan, English Separatist, and then a Baptist Separatist," and ended his days working with the Mennonites. He began meeting in England with 6070 English Separatists, in the face of "great danger." The persecution of religious nonconformists in England led Smyth to go into exile in Amsterdam with fellow Separatists from the congregation he had gathered in Lincolnshire, separate from the established church (Anglican). Smyth and his lay supporter, Thomas Helwys, together with those they led, broke with the other English exiles because Smyth and Helwys were convinced they should be baptized as believers. In 1609 Smyth first baptized himself and then baptized the others.
What is the answer to this question: Historians trace the earliest Baptist church back to when?
****
So... 1609

The problem: Answer a question about this article:
Patricia Ebrey writes that Tibet, like Joseon Korea and other neighboring states to the Ming, settled for its tributary status while there were no troops or governors of Ming China stationed in its territory. Laird writes that "after the Mongol troops left Tibet, no Ming troops replaced them." Wang and Nyima state that, despite the fact that the Ming refrained from sending troops to subdue Tibet and refrained from garrisoning Ming troops there, these measures were unnecessary so long as the Ming court upheld close ties with Tibetan vassals and their forces. However, there were instances in the 14th century when the Hongwu Emperor did use military force to quell unrest in Tibet. John D. Langlois writes that there was unrest in Tibet and western Sichuan, which the Marquis Mu Ying () was commissioned to quell in November 1378 after he established a Taozhou garrison in Gansu. Langlois notes that by October 1379, Mu Ying had allegedly captured 30,000 Tibetan prisoners and 200,000 domesticated animals. Yet invasion went both ways; the Ming general Qu Neng, under the command of Lan Yu, was ordered to repel a Tibetan assault into Sichuan in 1390.
When was the Marquis Mu Ying commissioned to quell?
****
The answer: November 1378

Problem: Please answer a question about the following article about Karl Popper:
Popper died of "complications of cancer, pneumonia and kidney failure" in Kenley at the age of 92 on 17 September 1994. He had been working continuously on his philosophy until two weeks before, when he suddenly fell terminally ill. After cremation, his ashes were taken to Vienna and buried at Lainzer cemetery adjacent to the ORF Centre, where his wife Josefine Anna Popper (called 'Hennie') had already been buried. Popper's estate is managed by his secretary and personal assistant Melitta Mew and her husband Raymond. Popper's manuscripts went to the Hoover Institution at Stanford University, partly during his lifetime and partly as supplementary material after his death. Klagenfurt University possesses Popper's library, including his precious bibliophilia, as well as hard copies of the original Hoover material and microfilms of the supplementary material. The remaining parts of the estate were mostly transferred to The Karl Popper Charitable Trust. In October 2008 Klagenfurt University acquired the copyrights from the estate.
How old was Popper when he died?
A: 92

In March 2001, 40 multi-national pharmaceutical companies brought litigation against South Africa for its Medicines Act, which allowed the generic production of antiretroviral drugs (ARVs) for treating HIV, despite the fact that these drugs were on-patent. HIV was and is an epidemic in South Africa, and ARVs at the time cost between 10,000 and 15,000 USD per patient per year. This was unaffordable for most South African citizens, and so the South African government committed to providing ARVs at prices closer to what people could afford. To do so, they would need to ignore the patents on drugs and produce generics within the country (using a compulsory license), or import them from abroad. After international protest in favour of public health rights (including the collection of 250,000 signatures by MSF), the governments of several developed countries (including The Netherlands, Germany, France, and later the US) backed the South African government, and the case was dropped in April of that year.

How much did ARV drugs cost patients yearly?
Answer: between 10,000 and 15,000 USD

The Hashimiyya movement (a sub-sect of the Kaysanites Shia), led by the Abbasid family, overthrew the Umayyad caliphate. The Abbasids were members of the Hashim clan, rivals of the Umayyads, but the word "Hashimiyya" seems to refer specifically to Abu Hashim, a grandson of Ali and son of Muhammad ibn al-Hanafiyya. According to certain traditions, Abu Hashim died in 717 in Humeima in the house of Muhammad ibn Ali, the head of the Abbasid family, and before dying named Muhammad ibn Ali as his successor. This tradition allowed the Abbasids to rally the supporters of the failed revolt of Mukhtar, who had represented themselves as the supporters of Muhammad ibn al-Hanafiyya.
Who led the Hashimiyya movement?
Abbasid family
