[Q]: Passage: Meanwhile, with the advent and popularity of Internet-based distribution of files in lossily-compressed audio formats such as MP3, sales of CDs began to decline in the 2000s. For example, between 2000 - 2008, despite overall growth in music sales and one anomalous year of increase, major-label CD sales declined overall by 20%, although independent and DIY music sales may be tracking better according to figures released 30 March 2009, and CDs still continue to sell greatly. As of 2012, CDs and DVDs made up only 34 percent of music sales in the United States. In Japan, however, over 80 percent of music was bought on CDs and other physical formats as of 2015. Question: What portion of music sales did CDs and DVDs account for in the United States as of 2012?
[A]: 34 percent

[Q]: Passage: Glass remained a luxury material, and the disasters that overtook Late Bronze Age civilizations seem to have brought glass-making to a halt. Indigenous development of glass technology in South Asia may have begun in 1730 BCE. In ancient China, though, glassmaking seems to have a late start, compared to ceramics and metal work. The term glass developed in the late Roman Empire. It was in the Roman glassmaking center at Trier, now in modern Germany, that the late-Latin term glesum originated, probably from a Germanic word for a transparent, lustrous substance. Glass objects have been recovered across the Roman empire in domestic, industrial and funerary contexts.[citation needed] Question: In what year did glassmaking begin in Asia?
[A]: 1730 BCE

[Q]: Passage: During the Second Sino-Japanese War, which led into World War II, much of Zhejiang was occupied by Japan and placed under the control of the Japanese puppet state known as the Reorganized National Government of China. Following the Doolittle Raid, most of the B-25 American crews that came down in China eventually made it to safety with the help of Chinese civilians and soldiers. The Chinese people who helped them, however, paid dearly for sheltering the Americans. The Imperial Japanese Army began the Zhejiang-Jiangxi Campaign to intimidate the Chinese out of helping downed American airmen. The Japanese killed an estimated 250,000 civilians while searching for Doolittle's men. Question: How many estimated civilians were killed by the Japanese searching for Doolittle's men?
[A]:
250,000
