[Q]: Extract the answer to the question from the following context. Question: The meaning of what word shows the relationship of the surviving witnesses? Context: Stemmatics, stemmology or stemmatology is a rigorous approach to textual criticism. Karl Lachmann (17931851) greatly contributed to making this method famous, even though he did not invent it. The method takes its name from the word stemma. The Ancient Greek word and its loanword in classical Latin stemmata may refer to "family trees". This specific meaning shows the relationships of the surviving witnesses (the first known example of such a stemma, albeit with the name, dates from 1827). The family tree is also referred to as a cladogram. The method works from the principle that "community of error implies community of origin." That is, if two witnesses have a number of errors in common, it may be presumed that they were derived from a common intermediate source, called a hyparchetype. Relations between the lost intermediates are determined by the same process, placing all extant manuscripts in a family tree or stemma codicum descended from a single archetype. The process of constructing the stemma is called recension, or the Latin recensio.

[Q]: Extract the answer to the question from the following context. Question: Of the things that the Kievan state exported, which was NOT a good? Context: The new Kievan state prospered due to its abundant supply of furs, beeswax, honey, and slaves for export, and because it controlled three main trade routes of Eastern Europe. In the north, Novgorod served as a commercial link between the Baltic Sea and the Volga trade route to the lands of the Volga Bulgars, the Khazars, and across the Caspian Sea as far as Baghdad, providing access to markets and products from Central Asia and the Middle East. Trade from the Baltic also moved south on a network of rivers and short portages along the Dnieper known as the "route from the Varangians to the Greeks," continuing to the Black Sea and on to Constantinople. Kiev was a central outpost along the Dnieper route and a hub with the east-west overland trade route between the Khazars and the Germanic lands of Central Europe. These commercial connections enriched Rus' merchants and princes, funding military forces and the construction of churches, palaces, fortifications, and further towns. Demand for luxury goods fostered production of expensive jewelry and religious wares, allowing their export, and an advanced credit and money-lending system may have also been in place.

[Q]: Extract the answer to the question from the following context. Question: Name a type of music used to describe Queen that does not include the word "rock" in it? Context: Queen composed music that drew inspiration from many different genres of music, often with a tongue-in-cheek attitude. The genres they have been associated with include progressive rock, symphonic rock, art rock, glam rock, hard rock, heavy metal, pop rock, and psychedelic rock. Queen also wrote songs that were inspired by diverse musical styles which are not typically associated with rock groups, such as opera, music hall, folk music, gospel, ragtime, and dance/disco. Several Queen songs were written with audience participation in mind, such as "We Will Rock You" and "We Are the Champions". Similarly, "Radio Ga Ga" became a live favourite because it would have "crowds clapping like they were at a Nuremberg rally".

[Q]: Extract the answer to the question from the following context. Question: Plymouth was bombed during when? Context: In the First World War, Devonport was the headquarters of Western Approaches Command until 1941 and Sunderland flying boats were operated by the Royal Australian Air Force. It was an important embarkation point for US troops for D-Day. The city was heavily bombed by the Luftwaffe, in a series of 59 raids known as the Plymouth Blitz. Although the dockyards were the principal targets, much of the city centre and over 3,700 houses were completely destroyed and more than 1,000 civilians lost their lives. This was largely due to Plymouth's status as a major port Charles Church was hit by incendiary bombs and partially destroyed in 1941 during the Blitz, but has not been demolished, as it is now an official permanent monument to the bombing of Plymouth during World War II.
