Question: Both Tacheng and Huozhou are located in what continent?
Context: Huozhou (), formerly Huo County or Huoxian, is a county-level city in Linfen, Shanxi Province, China. The Datong–Puzhou or Tongpu Railway (), is a major trunkline railroad in northern China, and the main axial railway of Shanxi Province.  The railway is located entirely within Shanxi and diagonally bisects the province from Datong in the northeast to Fenglingdu, near the village of Puzhou, in the southwest corner.  The line is named after Datong and Puzhou, and has a total length of 865 km .  The line is often referred to by its northern and southern halves with Taiyuan, the provincial capital as the midpoint.  Southern Tongpu Railway from Taiyuan to Fenglingdu is 513 km in length and was built from 1933 to 1935.  The Northern Tongpu Railway, from Datong to Taiyuan is 351 km in length and was built from 1933 to 1940.  Major cities and towns along route include Datong, Huairen, Shuozhou, Ningwu, Yuanping, Xinzhou, Taiyuan, Yuci, Taigu, Qi County, Pingyao, Huozhou, Hongdong, Linfen, Houma and Fenglingdu. Tacheng (Qoqek/Sawesek) or Chöchek is a county-level city (1994 est. pop.  56,400) and the administrative seat of Tacheng Prefecture, in northern Ili Kazakh Autonomous Prefecture, Xinjiang, one of the autonomous regions of China. World Park Base was a non-governmental year-round Antarctic base located at Cape Evans on Ross Island in the Ross Dependency.  The international environmental organization Greenpeace established World Park Base in 1987 in order to press its demand for the Antarctic Treaty nations to declare all of the continent of Antarctica a World Park.  This would make the entire continent off-limits to commercial exploitation and pollution, and permit only limited scientific research.  Greenpeace closed down and completely dismantled the base in 1992. Asia ( ) is Earth's largest and most populous continent, located primarily in the Eastern and Northern Hemispheres.  It shares the continental landmass of Eurasia with the continent of Europe and the continental landmass of Afro-Eurasia with both Europe and Africa.  Asia covers an area of 44,579,000 km2 , about 30% of Earth's total land area and 8.7% of the Earth's total surface area.  The continent, which has long been home to the majority of the human population, was the site of many of the first civilizations.  Asia is notable for not only its overall large size and population, but also dense and large settlements as well as vast barely populated regions within the continent of /1e9 round 1 billion people, or roughly 60% of the world's population. Quentovic was a Frankish emporium in the Early Middle Ages that was located on the European continent close to the English Channel.  The town no longer exists, but until recently it was thought to have been situated near the mouth of the Canche River in what is today the French commune of Étaples.  Archaeological discoveries led by David Hill in the 1980s found that the actual location of Quentovic was east of Étaples, in what is now the commune of La Calotterie.  It was an important trading place for the Franks and its port linked the continent to England, specifically to the southeastern county of Kent.  From what we know today, Quentovic was founded by a Neustrian king in the early 6th century.  It was one of the two most prominent Frankish ports in the north (the other being Dorestad) until it was abandoned, probably in the 11th century.  Merchants were drawn to this place because the number of trading posts at the time was limited.  Quentovic was also the place where Anglo-Saxon monks would cross the English Channel on their pilgrimage to Rome.  A lack of physical evidence, and the sudden disappearance of this emporium, make the town difficult to interpret.  Some of the most important historical evidence on Quentovic comes from documents of taxation and especially through the town’s minting of coinage.  Coins minted during both the Merovingian and the Carolingian dynasties have been found. Tacheng (Tarbagatay) Prefecture is located in northern Xinjiang, People's Republic of China.  It has an area of 98,824 km² and a population of 892,397 (2000).  It is a part of Ili Kazakh Autonomous Prefecture.  The prefecture level city of Karamay forms a separate enclave in the middle of Tacheng. Europe is a continent located entirely in the Northern Hemisphere and mostly in the Eastern Hemisphere.  Europe is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, and the Mediterranean Sea to the south.  It comprises the westernmost part of Eurasia.  Europe is generally considered as separated from Asia by the watershed divides of the Ural and Caucasus Mountains, the Ural River, the Caspian and Black Seas, and the waterways of the Turkish Straits.  Yet the non-oceanic borders of Europe—a concept dating back to classical antiquity—are arbitrary and amount to a historical and social construct.  The primarily physiographic term "continent" as applied to Europe also incorporates cultural and political elements whose discontinuities are not always reflected by the continent's current overland boundary with Asia. This is a list of herbaria, organized first by continent where the herbarium is located, then within each continent by size of the collection.  A herbarium ("plural" "herbaria") is a collection of preserved plant specimens.  These specimens may be whole plants or plant parts: these will usually be in a dried form, mounted on a sheet, but depending upon the material may also be kept in alcohol or other preservative.  The same term is often used in mycology to describe an equivalent collection of preserved fungi and in phycology to describe a collection of algae.
