Problem: Estonian language:

It should be noted that Estonian words and names quoted in international publications from Soviet sources are often back-transliterations from the Russian transliteration. Examples are the use of "ya" for "a" (e.g. Pyarnu instead of Parnu), "y" instead of "o" (e.g., Pylva instead of Polva) and "yu" instead of "u" (e.g., Pyussi instead of Pussi). Even in the Encyclopdia Britannica one can find "ostrov Khiuma", where "ostrov" means "island" in Russian and "Khiuma" is back-transliteration from Russian instead of "Hiiumaa" (Hiiumaa > () > Khiuma).

What famous encyclopedia contains a Estonian back-transliteration of Russian?

Problem: Longer works are often divided into self-contained pieces, called movements, often with contrasting characters or moods. For instance, symphonies written during the Classical period are usually divided into four movements: (1) an opening Allegro in sonata form, (2) a slow movement, (3) a minuet or scherzo, and (4) a final Allegro. These movements can then be further broken down into a hierarchy of smaller units: first sections, then periods, and finally phrases.
A movement broken up further is called what?
---
Answer: sections

The traditional Charleston accent has long been noted in the state and throughout the South. It is typically heard in wealthy white families who trace their families back generations in the city. It has ingliding or monophthongal long mid-vowels, raises ay and aw in certain environments, and is nonrhotic. Sylvester Primer of the College of Charleston wrote about aspects of the local dialect in his late 19th-century works: "Charleston Provincialisms" (1887) and "The Huguenot Element in Charleston's Provincialisms", published in a German journal. He believed the accent was based on the English as it was spoken by the earliest settlers, therefore derived from Elizabethan England and preserved with modifications by Charleston speakers. The rapidly disappearing "Charleston accent" is still noted in the local pronunciation of the city's name. Some elderly (and usually upper-class) Charleston natives ignore the 'r' and elongate the first vowel, pronouncing the name as "Chah-l-ston". Some observers attribute these unique features of Charleston's speech to its early settlement by French Huguenots and Sephardic Jews (who were primarily English speakers from London), both of whom played influential roles in Charleston's early development and history.[citation needed]
To which three early cultures are the unique characteristics of Charleston's accent attributed to?

Context and question: One way to decrease stigma may be through the promotion of "TB clubs", where those infected may share experiences and offer support, or through counseling. Some studies have shown TB education programs to be effective in decreasing stigma, and may thus be effective in increasing treatment adherence. Despite this, studies on relationship between reduced stigma and mortality are lacking as of 2010, and similar efforts to decrease stigma surrounding AIDS have been minimally effective. Some have claimed the stigma to be worse than the disease, and healthcare providers may unintentionally reinforce stigma, as those with TB are often perceived as difficult or otherwise undesirable. A greater understanding of the social and cultural dimensions of tuberculosis may also help with stigma reduction.
Education about TB seems to decrease the stigma of the disease and lead to what other positive effect?
Answer: increasing treatment adherence

Question: The MC controls the conferencing while it is active on the signaling plane, which is simply where the system manages conferencing creation, endpoint signaling and in-conferencing controls. This component negotiates parameters with every endpoint in the network and controls conferencing resources. While the MC controls resources and signaling negotiations, the MP operates on the media plane and receives media from each endpoint. The MP generates output streams from each endpoint and redirects the information to other endpoints in the conference.
Is there an answer to this question: On what plane does the MC operate?

Answer: the media plane
