Context and question: Russian is notable for its distinction based on palatalization of most of the consonants. While /k/, /ɡ/, /x/ do have palatalized allophones [kʲ, ɡʲ, xʲ], only /kʲ/ might be considered a phoneme, though it is marginal and generally not considered distinctive (the only native minimal pair which argues for /kʲ/ to be a separate phoneme is "это ткёт" ([ˈɛtə tkʲɵt], 'it weaves')/"этот кот" ([ˈɛtət 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 /tʲ/ and /dʲ/, the tongue is raised enough to produce slight frication (affricate sounds). These sounds: /t, d, ts, s, z, n and rʲ/ are dental, that is pronounced with the tip of the tongue against the teeth rather than against the alveolar ridge.
How are 'dental' sounds pronounced?
Answer: with the tip of the tongue against the teeth rather than against the alveolar ridge
Context and question: The ancient-Chamorro society had four classes: chamorri (chiefs), matua (upper class), achaot (middle class), and mana'chang (lower class).:20–21 The matua were located in the coastal villages, which meant they had the best access to fishing grounds, whereas the mana'chang were located in the interior of the island. Matua and mana'chang rarely communicated with each other, and matua often used achaot as intermediaries. There were also "makåhna" (similar to shamans), skilled in healing and medicine. Belief in spirits of ancient Chamorros called "Taotao mo'na" still persists as a remnant of pre-European culture. Their society was organized along matrilineal clans.:21
Where did the chamorri live?
Answer: unanswerable
Context and question: The logical format of an audio CD (officially Compact Disc Digital Audio or CD-DA) is described in a document produced in 1980 by the format's joint creators, Sony and Philips. The document is known colloquially as the Red Book CD-DA after the colour of its cover. The format is a two-channel 16-bit PCM encoding at a 44.1 kHz sampling rate per channel. Four-channel sound was to be an allowable option within the Red Book format, but has never been implemented. Monaural audio has no existing standard on a Red Book CD; thus, mono source material is usually presented as two identical channels in a standard Red Book stereo track (i.e., mirrored mono); an MP3 CD, however, can have audio file formats with mono sound.
Do CDs have a two or four channel format?
Answer:
two-channel
