Problem: Karlheinz Brandenburg used a CD recording of Suzanne Vega's song "Tom's Diner" to assess and refine the MP3 compression algorithm. This song was chosen because of its nearly monophonic nature and wide spectral content, making it easier to hear imperfections in the compression format during playbacks. Some refer to Suzanne Vega as "The mother of MP3". This particular track has an interesting property in that the two channels are almost, but not completely, the same, leading to a case where Binaural Masking Level Depression causes spatial unmasking of noise artifacts unless the encoder properly recognizes the situation and applies corrections similar to those detailed in the MPEG-2 AAC psychoacoustic model. Some more critical audio excerpts (glockenspiel, triangle, accordion, etc.) were taken from the EBU V3/SQAM reference compact disc and have been used by professional sound engineers to assess the subjective quality of the MPEG Audio formats.
Excerpts were taken from which reference compact disc to assess the subjective quality of the MPEG audio formats?
The answer is the following: EBU V3/SQAM

Problem: The early Qing military was rooted in the Eight Banners first developed by Nurhaci to organize Jurchen society beyond petty clan affiliations. There were eight banners in all, differentiated by color. The yellow, bordered yellow, and white banners were known as the "Upper Three Banners" and were under the direct command of the emperor. Only Manchus belonging to the Upper Three Banners, and selected Han Chinese who had passed the highest level of martial exams could serve as the emperor's personal bodyguards. The remaining Banners were known as the "Lower Five Banners." They were commanded by hereditary Manchu princes descended from Nurhachi's immediate family, known informally as the "Iron cap princes". Together they formed the ruling council of the Manchu nation as well as high command of the army. Nurhachi's son Hong Taiji expanded the system to include mirrored Mongol and Han Banners. After capturing Beijing in 1644, the relatively small Banner armies were further augmented by the Green Standard Army, made up of those Ming troops who had surrendered to the Qing, which eventually outnumbered Banner troops three to one. They maintained their Ming era organization and were led by a mix of Banner and Green Standard officers.[citation needed]
What ethnicity made up the Upper Three Banners?
The answer is the following: Manchus
