Problem: Extract the answer to the question from the following context. Question: How were the Qing Goverment's de facto first-line troops sustained before changing their name? Context: First, the Yongying system signaled the end of Manchu dominance in Qing military establishment. Although the Banners and Green Standard armies lingered on as a drain on resources, henceforth the Yongying corps became the Qing government's de facto first-line troops. Second, the Yongying corps were financed through provincial coffers and were led by regional commanders, weakening central government's grip on the whole country. Finally, the nature of Yongying command structure fostered nepotism and cronyism amongst its commanders, who laid the seeds of regional warlordism in the first half of the 20th century.

Context: In the Colonial America of 1619, John Rolfe used negars in describing the slaves who were captured from West Africa and then shipped to the Virginia colony. Later American English spellings, neger and neggar, prevailed in a northern colony, New York under the Dutch, and in metropolitan Philadelphia's Moravian and Pennsylvania Dutch communities; the African Burial Ground in New York City originally was known by the Dutch name "Begraafplaats van de Neger" (Cemetery of the Negro); an early US occurrence of neger in Rhode Island, dates from 1625. Thomas Jefferson also used the term "black" in his Notes on the State of Virginia in allusion to the slave populations.

input question: Extract the answer to the question from the following context. Question: Who did the SBC wrong? Context: On 20 June 1995, the Southern Baptist Convention voted to adopt a resolution renouncing its racist roots and apologizing for its past defense of slavery. More than 20,000 Southern Baptists registered for the meeting in Atlanta. The resolution declared that messengers, as SBC delegates are called, "unwaveringly denounce racism, in all its forms, as deplorable sin" and "lament and repudiate historic acts of evil such as slavery from which we continue to reap a bitter harvest." It offered an apology to all African-Americans for "condoning and/or perpetuating individual and systemic racism in our lifetime" and repentance for "racism of which we have been guilty, whether consciously or unconsciously." Although Southern Baptists have condemned racism in the past, this was the first time the predominantly white convention had dealt specifically with the issue of slavery.???

Extract the answer to the question from the following context. Question: What was opened with this system? Context: The Nippon Hoso Kyokai (NHK, the Japan Broadcasting Corporation) began conducting research to "unlock the fundamental mechanism of video and sound interactions with the five human senses" in 1964, after the Tokyo Olympics. NHK set out to create an HDTV system that ended up scoring much higher in subjective tests than NTSC's previously dubbed "HDTV". This new system, NHK Color, created in 1972, included 1125 lines, a 5:3 aspect ratio and 60 Hz refresh rate. The Society of Motion Picture and Television Engineers (SMPTE), headed by Charles Ginsburg, became the testing and study authority for HDTV technology in the international theater. SMPTE would test HDTV systems from different companies from every conceivable perspective, but the problem of combining the different formats plagued the technology for many years.
