Problem: MP3:

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?

A: variable bitrate audio

Problem: On the second day, U.S. reconnaissance planes located Ozawa's fleet, 275 miles (443 km)[citation needed] away, and submarines sank two Japanese carriers. Mitscher launched 230 torpedo planes and dive bombers. He then discovered the enemy was actually another 60 miles (97 km)[citation needed] further off, out of aircraft range (based on a roundtrip flight). Mitscher decided this chance to destroy the Japanese fleet was worth the risk of aircraft losses due to running out of fuel on the return flight. Overall, the U.S. lost 130 planes and 76 aircrew; however, Japan lost 450 planes, three carriers, and 445 aircrew. The Imperial Japanese Navy's carrier force was effectively destroyed.
How many U.S. aircrews were lost?

Answer: 76

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Some organisms have multiple copies of chromosomes: diploid, triploid, tetraploid and so on. In classical genetics, in a sexually reproducing organism (typically eukarya) the gamete has half the number of chromosomes of the somatic cell and the genome is a full set of chromosomes in a diploid cell. The halving of the genetic material in gametes is accomplished by the segregation of homologous chromosomes during meiosis. In haploid organisms, including cells of bacteria, archaea, and in organelles including mitochondria and chloroplasts, or viruses, that similarly contain genes, the single or set of circular or linear chains of DNA (or RNA for some viruses), likewise constitute the genome. The term genome can be applied specifically to mean what is stored on a complete set of nuclear DNA (i.e., the "nuclear genome") but can also be applied to what is stored within organelles that contain their own DNA, as with the "mitochondrial genome" or the "chloroplast genome". Additionally, the genome can comprise non-chromosomal genetic elements such as viruses, plasmids, and transposable elements.
A gamate has how many chromosomes relative to a somatic cell?
A: half

Context and question: Insects (from Latin insectum, a calque of Greek [entomon], "cut into sections") are a class of invertebrates within the arthropod phylum that have a chitinous exoskeleton, a three-part body (head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. They are the most diverse group of animals on the planet, including more than a million described species and representing more than half of all known living organisms. The number of extant species is estimated at between six and ten million, and potentially represent over 90% of the differing animal life forms on Earth. Insects may be found in nearly all environments, although only a small number of species reside in the oceans, a habitat dominated by another arthropod group, crustaceans.
What type of exoskeleton do insects have?
Answer: chitinous

Question: There is confusion currently as to the name of the eldest Vinaccia luthier who first ran the shop. His name has been put forth as Gennaro Vinaccia (active c. 1710 to c. 1788) and Nic. Vinaccia. His son Antonio Vinaccia was active c. 1734 to c. 1796. An early extant example of a mandolin is one built by Antonio Vinaccia in 1759, which resides at the University of Edinburgh. Another is by Giuseppe Vinaccia, built in 1893, is also at the University of Edinburgh. The earliest extant mandolin was built in 1744 by Antonio's son, Gaetano Vinaccia. It resides in the Conservatoire Royal de Musique in Brussels, Belgium.
Is there an answer to this question: Who built an early mandolin in 1795?

Answer: unanswerable

Question: Burke believed that property was essential to human life. Because of his conviction that people desire to be ruled and controlled, the division of property formed the basis for social structure, helping develop control within a property-based hierarchy. He viewed the social changes brought on by property as the natural order of events, which should be taking place as the human race progressed. With the division of property and the class system, he also believed that it kept the monarch in check to the needs of the classes beneath the monarch. Since property largely aligned or defined divisions of social class, class too, was seen as naturalpart of a social agreement that the setting of persons into different classes, is the mutual benefit of all subjects. Concern for property is not Burke's only influence. As Christopher Hitchens summarises, "If modern conservatism can be held to derive from Burke, it is not just because he appealed to property owners in behalf of stability but also because he appealed to an everyday interest in the preservation of the ancestral and the immemorial."
Is there an answer to this question: What did Burke think a social hierarchy should be based on?

Answer:
property
