Problem: MP3:

There is no scale factor band 21 (sfb21) for frequencies above approx 16 kHz, forcing the encoder to choose between less accurate representation in band 21 or less efficient storage in all bands below band 21, the latter resulting in wasted bitrate in VBR encoding.

What can scale factor band 21 be shortened to?
---
A: sfb21

Problem: Czech has one of the most phonemic orthographies of all European languages. Its thirty-one graphemes represent thirty sounds (in most dialects, i and y have the same sound), and it contains only one digraph: ch, which follows h in the alphabet. As a result, some of its characters have been used by phonologists to denote corresponding sounds in other languages. The characters q, w and x appear only in foreign words. The hacek () is used with certain letters to form new characters: s, z, and c, as well as n, e, r, t, and d (the latter five uncommon outside Czech). The last two letters are sometimes written with a comma above (', an abbreviated hacek) because of their height. The character o exists only in loanwords and onomatopoeia.
What letters are common in loanwords?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Yet the most impressive aesthetic works were done among the scholars and urban elite. Calligraphy and painting remained a central interest to both court painters and scholar-gentry who considered the Four Arts part of their cultural identity and social standing. The painting of the early years of the dynasty included such painters as the orthodox Four Wangs and the individualists Bada Shanren (16261705) and Shitao (16411707). The nineteenth century saw such innovations as the Shanghai School and the Lingnan School which used the technical skills of tradition to set the stage for modern painting.
What two schools of art were created in the 19th century?
A: Shanghai School and the Lingnan School

Context and question: Some of Nasser's liberal and Islamist critics in Egypt, including the founding members of the New Wafd Party and writer Jamal Badawi, dismissed Nasser's popular appeal with the Egyptian masses during his presidency as being the product of successful manipulation and demagoguery. Egyptian political scientist Alaa al-Din Desouki blamed the 1952 revolution's shortcomings on Nasser's concentration of power, and Egypt's lack of democracy on Nasser's political style and his government's limitations on freedom of expression and political participation.
To what did critics attribute Nasser's popular appeal?
Answer: successful manipulation and demagoguery

Question: A later literary standard, dating from the later 10th century, arose under the influence of Bishop thelwold of Winchester, and was followed by such writers as the prolific lfric of Eynsham ("the Grammarian"). This form of the language is known as the "Winchester standard", or more commonly as Late West Saxon. It is considered to represent the "classical" form of Old English. It retained its position of prestige until the time of the Norman Conquest, after which English ceased for a time to be of importance as a literary language.
Is there an answer to this question: What writer helped develop the Winchester standard?

Answer: unanswerable

Question: Russian is notable for its distinction based on palatalization of most of the consonants. While /k/, //, /x/ do have palatalized allophones [k, , x], only /k/ might be considered a phoneme, though it is marginal and generally not considered distinctive (the only native minimal pair which argues for /k/ to be a separate phoneme is " " ([t tkt], 'it weaves')/" " ([tt kot], 'this cat')). Palatalization means that the center of the tongue is raised during and after the articulation of the consonant. In the case of /t/ and /d/, the tongue is raised enough to produce slight frication (affricate sounds). These sounds: /t, d, ts, s, z, n and r/ are dental, that is pronounced with the tip of the tongue against the teeth rather than against the alveolar ridge.
Is there an answer to this question: How are 'dental' sounds pronounced?

Answer:
with the tip of the tongue against the teeth rather than against the alveolar ridge
