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

In many ways, the Paleocene continued processes that had begun during the late Cretaceous Period. During the Paleocene, the continents continued to drift toward their present positions. Supercontinent Laurasia had not yet separated into three continents. Europe and Greenland were still connected. North America and Asia were still intermittently joined by a land bridge, while Greenland and North America were beginning to separate. The Laramide orogeny of the late Cretaceous continued to uplift the Rocky Mountains in the American west, which ended in the succeeding epoch. South and North America remained separated by equatorial seas (they joined during the Neogene); the components of the former southern supercontinent Gondwana continued to split apart, with Africa, South America, Antarctica and Australia pulling away from each other. Africa was heading north toward Europe, slowly closing the Tethys Ocean, and India began its migration to Asia that would lead to a tectonic collision and the formation of the Himalayas.
What mountain chain in the Cretaceous was lifted as a result of the Laramide oregeny?
the Rocky Mountains

Input: Memory
In contrast, procedural memory (or implicit memory) is not based on the conscious recall of information, but on implicit learning. It can best be summarized as remember how to do something. Procedural memory is primarily employed in learning motor skills and should be considered a subset of implicit memory. It is revealed when one does better in a given task due only to repetition - no new explicit memories have been formed, but one is unconsciously accessing aspects of those previous experiences. Procedural memory involved in motor learning depends on the cerebellum and basal ganglia.

What set of skills is reliant on procedural memory?
Output: motor skills

Input: Article: UNFPA works in partnership with governments, along with other United Nations agencies, communities, NGOs, foundations and the private sector, to raise awareness and mobilize the support and resources needed to achieve its mission to promote the rights and health of women and young people.

Now answer this question: In addition to mobilizing support and resources, what does UNFPA do with its partners?

Output: raise awareness

Article: In Kazakhstan on June 19, 1989, young men carrying guns, firebombs, iron bars and stones rioted in Zhanaozen, causing a number of deaths. The youths tried to seize a police station and a water-supply station. They brought public transportation to a halt and shut down various shops and industries. By June 25, the rioting had spread to five other towns near the Caspian Sea. A mob of about 150 people armed with sticks, stones and metal rods attacked the police station in Mangishlak, about 90 miles from Zhanaozen, before they were dispersed by government troops flown in by helicopters. Mobs of young people also rampaged through Yeraliev, Shepke, Fort-Shevchenko and Kulsary, where they poured flammable liquid on trains housing temporary workers and set them on fire.

Question: Who were the rioters?
Ans: young men

Input: FC Barcelona
In 1980, when the stadium was in need of redesign to meet UEFA criteria, the club raised money by offering supporters the opportunity to inscribe their name on the bricks for a small fee. The idea was popular with supporters, and thousands of people paid the fee. Later this became the centre of controversy when media in Madrid picked up reports that one of the stones was inscribed with the name of long-time Real Madrid chairman and Franco supporter Santiago Bernabeu. In preparation for the 1992 Summer Olympics two tiers of seating were installed above the previous roofline. It has a current capacity of 99,354 making it the largest stadium in Europe.

What is the capacity of the Barcelona stadium?
Output:
99,354
