Problem: A more sophisticated MP3 encoder can produce variable bitrate audio. MPEG audio may use bitrate switching on a per-frame basis, but only layer III decoders must support it. VBR is used when the goal is to achieve a fixed level of quality. The final file size of a VBR encoding is less predictable than with constant bitrate. Average bitrate is VBR implemented as a compromise between the two: the bitrate is allowed to vary for more consistent quality, but is controlled to remain near an average value chosen by the user, for predictable file sizes. Although an MP3 decoder must support VBR to be standards compliant, historically some decoders have bugs with VBR decoding, particularly before VBR encoders became widespread.
What kind of audio can a sophisticated MP3 encoder produce?
The answer is the following: variable bitrate audio


For Germany, because an autarkic economic approach or an alliance with Britain were impossible, closer relations with the Soviet Union to obtain raw materials became necessary, if not just for economic reasons alone. Moreover, an expected British blockade in the event of war would create massive shortages for Germany in a number of key raw materials. After the Munich agreement, the resulting increase in German military supply needs and Soviet demands for military machinery, talks between the two countries occurred from late 1938 to March 1939. The third Soviet Five Year Plan required new infusions of technology and industrial equipment.[clarification needed] German war planners had estimated serious shortfalls of raw materials if Germany entered a war without Soviet supply.
Who believed they needed a supply line from the Soviet Union to sustain another war? 
Germany


Input: Korean War
A major consideration was the possible Soviet reaction in the event that the US intervened. The Truman administration was fretful that a war in Korea was a diversionary assault that would escalate to a general war in Europe once the United States committed in Korea. At the same time, "[t]here was no suggestion from anyone that the United Nations or the United States could back away from [the conflict]". Yugoslavia–a possible Soviet target because of the Tito-Stalin Split—was vital to the defense of Italy and Greece, and the country was first on the list of the National Security Council's post-North Korea invasion list of "chief danger spots". Truman believed if aggression went unchecked a chain reaction would be initiated that would marginalize the United Nations and encourage Communist aggression elsewhere. The UN Security Council approved the use of force to help the South Koreans and the US immediately began using what air and naval forces that were in the area to that end. The Administration still refrained from committing on the ground because some advisers believed the North Koreans could be stopped by air and naval power alone.

What agency approved the use of force in South Korea?
Output: The UN Security Council


Input: Article: In July 2015, Eton accidentally sent emails to 400 prospective students, offering them conditional entrance to the school in September 2017. The email was intended for nine students, but an IT glitch caused the email to be sent to 400 additional families, who didn't necessarily have a place. In response, the school issued the following statement: "This error was discovered within minutes and each family was immediately contacted to notify them that it should be disregarded and to apologise. We take this type of incident very seriously indeed and so a thorough investigation, overseen by the headmaster Tony Little and led by the tutor for admissions, is being carried out to find out exactly what went wrong and ensure it cannot happen again. Eton College offers its sincere apologies to those boys concerned and their families. We deeply regret the confusion and upset this must have caused."

Now answer this question: When was an accidental email sent to potential students of Eton that warranted a personal apology to each family?

Output: July 2015


Article: Home-based manufacturing operations were active year round. Families willingly deployed their children in these income generating home enterprises. In many cases, men worked from home. In France, over 58 percent of garment workers operated out of their homes; in Germany, the number of full-time home operations nearly doubled between 1882 and 1907; and in the United States, millions of families operated out of home seven days a week, year round to produce garments, shoes, artificial flowers, feathers, match boxes, toys, umbrellas and other products. Children aged 5–14 worked alongside the parents. Home-based operations and child labour in Australia, Britain, Austria and other parts of the world was common. Rural areas similarly saw families deploying their children in agriculture. In 1946, Frieda Miller - then Director of United States Department of Labour - told the International Labour Organisation that these home-based operations offered, "low wages, long hours, child labour, unhealthy and insanitary working conditions."

Question: In 1946 who was the Director of the United States Department of Labour?
Ans: Frieda Miller
