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.
What is the only minimal pair that shows g is a separate phoneme?
A: unanswerable

The historical study of Cubism began in the late 1920s, drawing at first from sources of limited data, namely the opinions of Guillaume Apollinaire. It came to rely heavily on Daniel-Henry Kahnweiler's book Der Weg zum Kubismus (published in 1920), which centered on the developments of Picasso, Braque, Leger, and Gris. The terms "analytical" and "synthetic" which subsequently emerged have been widely accepted since the mid-1930s. Both terms are historical impositions that occurred after the facts they identify. Neither phase was designated as such at the time corresponding works were created. "If Kahnweiler considers Cubism as Picasso and Braque," wrote Daniel Robbins, "our only fault is in subjecting other Cubists' works to the rigors of that limited definition."
When did the historical study of Cubism begin?
A: in the late 1920s

Efforts by local kings to fight the invaders led to the formation of new political entities. In Anglo-Saxon England, King Alfred the Great (r. 871899) came to an agreement with the Viking invaders in the late 9th century, resulting in Danish settlements in Northumbria, Mercia, and parts of East Anglia. By the middle of the 10th century, Alfred's successors had conquered Northumbria, and restored English control over most of the southern part of Great Britain. In northern Britain, Kenneth MacAlpin (d. c. 860) united the Picts and the Scots into the Kingdom of Alba. In the early 10th century, the Ottonian dynasty had established itself in Germany, and was engaged in driving back the Magyars. Its efforts culminated in the coronation in 962 of Otto I (r. 936973) as Holy Roman Emperor. In 972, he secured recognition of his title by the Byzantine Empire, which he sealed with the marriage of his son Otto II (r. 967983) to Theophanu (d. 991), daughter of an earlier Byzantine Emperor Romanos II (r. 959963). By the late 10th century Italy had been drawn into the Ottonian sphere after a period of instability; Otto III (r. 9961002) spent much of his later reign in the kingdom. The western Frankish kingdom was more fragmented, and although kings remained nominally in charge, much of the political power devolved to the local lords.
In what year did Otto I become Holy Roman Emperor?
A: 962

Thermal conductivity gauges rely on the fact that the ability of a gas to conduct heat decreases with pressure. In this type of gauge, a wire filament is heated by running current through it. A thermocouple or Resistance Temperature Detector (RTD) can then be used to measure the temperature of the filament. This temperature is dependent on the rate at which the filament loses heat to the surrounding gas, and therefore on the thermal conductivity. A common variant is the Pirani gauge which uses a single platinum filament as both the heated element and RTD. These gauges are accurate from 10 torr to 103 torr, but they are sensitive to the chemical composition of the gases being measured.
How do thermal conductivity gauges use a single platinum filament as?
