[EX Q]: Context: Hong Kong, officially the Hong Kong Special Administrative Region of the People's Republic of China, is an autonomous territory on the Pearl River Delta of East Asia. Macau lies across the delta to the west, and the Chinese province of Guangdong borders the territory to the north. With a total land area of and a population of over 7.3 million of various nationalities, it ranks as the world's fourth most densely populated sovereign state or territory., Mainland China, also known as the Chinese mainland or simply the mainland, is the geopolitical area under the direct jurisdiction of the People's Republic of China (PRC). It generally excludes the Special Administrative Regions of Hong Kong and Macau; however, it usually includes Hainan. The term "mainland China", which avoids calling the area simply "China" and thereby recognizing the founding of the PRC as "the" "China", was coined by the Kuomintang (KMT) after receiving control of Taiwan from Japan after World War II. By 1949, the KMT-led Republic of China (ROC) government was defeated in the Chinese Civil War in mainland China and fled to the island of Taiwan where the KMT pledged to "retake the Mainland". The KMT considers both sides of the Taiwan Strait (including Taiwan), as (one) "China" and one country, whereas Taiwan's Democratic Progressive Party (DPP) considers only mainland China as "China" and Taiwan (ROC) as "Taiwan" and maintains that they are different countries., The Communist Party of China (CPC) is the founding and ruling political party of the People's Republic of China (PRC). The CPC is the sole governing party of China, although it coexists alongside eight other legal parties that comprise the United Front; these parties, however, hold no real power or independence from the CPC. It was founded in 1921, chiefly by Chen Duxiu and Li Dazhao. The party grew quickly, and by 1949 the CPC had driven the nationalist Kuomintang (KMT) government from mainland China after the Chinese Civil War, thus leading to the establishment of the People's Republic of China. The CPC is currently the world's second largest political party with a membership of 88.76 million as of 2016 (while the Indian Bharatiya Janata Party appears to have remained the largest with a membership of 110 million as of the previous year, 2015). It also controls the world's largest armed force, the People's Liberation Army. , Musical theatre is a form of theatrical performance that combines songs, spoken dialogue, acting, and dance. The story and emotional content of a musical humor, pathos, love, anger are communicated through the words, music, movement and technical aspects of the entertainment as an integrated whole.

Great powers characteristically possess military and economic strength, as well as diplomatic and soft power influence, which may cause middle or small powers to consider the great powers' opinions before taking actions of their own. International relations theorists have posited that great power status can be characterized into power capabilities, spatial aspects, and status dimensions., Chinese opera is a popular form of drama and musical theatre in China with roots going back to the early periods in China. It is a composite performance art that is an amalgamation of various art forms that existed in ancient China, and evolved gradually over more than a thousand years, reaching its mature form in the 13th century during the Song Dynasty. Early forms of Chinese drama are simple, but over time they incorporated various art forms, such as music, song and dance, martial arts, acrobatics, as well as literary art forms to become Chinese opera., The Song dynasty (9601279) was an era of Chinese history that began in 960 and continued until 1279.

[EX Q]: Context: Symphonic metal is a subgenre of metal music which combines the characteristics of this genre, such as heavy drums and guitars, with different elements of classical music including symphonic instruments, choirs and on occasion, a full symphony orchestra. Keyboards reminiscent of power metal also often find a dominant place in this subgenre.
Symphonic metal bands often feature classically trained female vocalists, giving rise to the nickname opera metal or operatic metal, and it is not uncommon for them to feature a second vocalist performing growls, a more common characteristic of gothic metal.
Perhaps the most typical and prominent examples of symphonic metal bands are Finnish band Nightwish, Dutch bands Within Temptation, Delain and Epica, and Swedish band Therion, all four of which place a large focus on elements prevalent in film scores on top of the more basic classical components utilized more widely in the genre., Black metal is an extreme subgenre and subculture of heavy metal music. Common traits include fast tempos, a shrieking vocal style, heavily distorted guitars played with tremolo picking, raw (lo-fi) recording, unconventional song structures, and an emphasis on atmosphere. Artists often appear in corpse paint and adopt pseudonyms., Lake of Sorrow is the debut studio album by the Norwegian gothic metal band The Sins of Thy Beloved . It was recorded at Sound Suite Studio in August , 1998 and released the same year through Napalm Records ., Gothic metal (or goth metal) is a fusion genre combining the heaviness of heavy metal with the dark atmospheres of gothic rock. The music of gothic metal is diverse with bands known to adopt the gothic approach to different styles of heavy metal music. The genre originated during the early 1990s in Europe originally as an outgrowth of death-doom, a fusion of death metal and doom metal. Lyrics are generally dark and introspective with inspiration from gothic fiction as well as personal experiences., Gothic fiction, which is largely known by the subgenre of Gothic horror, is a genre or mode of literature and film that combines fiction and horror, death, and at times romance. Its origin is attributed to English author Horace Walpole, with his 1764 novel "The Castle of Otranto", subtitled (in its second edition) "A Gothic Story." The effect of Gothic fiction feeds on a pleasing sort of terror, an extension of Romantic literary pleasures that were relatively new at the time of Walpole's novel. It originated in England in the second half of the 18th century and had much success in the 19th, as witnessed by Mary Shelleys "Frankenstein" and the works of Edgar Allan Poe. Another well known novel in this genre, dating from the late Victorian era, is Bram Stokers "Dracula". The name "Gothic" refers to the (pseudo)-medieval buildings, emulating Gothic architecture, in which many of these stories take place. This extreme form of romanticism was very popular in England and Germany. The English Gothic novel also led to new novel types such as the German "Schauerroman" and the French "Georgia"., Brant Bjork (born March 19, 1973) is an American musician, singer, songwriter, multi-instrumentalist, and producer from Palm Desert, California. He is perhaps best known as the drummer and founder of the influential Californian stoner rock band Kyuss. Bjork played in Vista Chino, along with former Kyuss vocalist John Garcia. Until October 2014 when Nick Oliveri announced that there was a falling out and that Bjork and Garcia would continue working on their solo projects. He is one of the more notable figures in the stoner rock and Palm Desert scenes., Gothic rock (also referred to as goth rock or simply goth) is a musical subgenre of post-punk and alternative rock that formed during the late 1970s. Gothic rock bands grew from the strong ties they had to the English punk rock and emerging post-punk scenes. Proto-gothic bands include Siouxsie and the Banshees, Joy Division, Bauhaus and the Cure., Power metal is a subgenre of heavy metal combining characteristics of traditional metal with speed metal, often within symphonic context. Generally, power metal is characterized by a more uplifting sound, instead of the heaviness and dissonance prevalent in styles such as doom metal and death metal. Power metal bands usually have anthem-like songs with fantasy-based subject matter and strong choruses, thus creating a theatrical, dramatic and emotionally "powerful" sound. The term was first used in the middle of the 1980s and refers to two different but related styles: the first pioneered and largely practiced in North America with a harder sound similar to speed metal, and a later more widespread and popular style based in Europe (especially Scandinavia, Germany, Greece and Italy), South America (especially Brazil and Argentina) and Japan, with a lighter, more melodic sound and frequent use of keyboards., Karma to Burn, sometimes known as K2B, is a desert rock/stoner rock band from Morgantown, West Virginia comprising guitarist William Mecum, bassist Eric Clutter, and drummer Evan Devine. The band are noted for their uncompromising, mostly instrumental sound., Doom metal is an extreme style of heavy metal music that typically uses slower tempos, low-tuned guitars and a much "thicker" or "heavier" sound than other metal genres. Both the music and the lyrics intend to evoke a sense of despair, dread, and impending doom. The genre is strongly influenced by the early work of Black Sabbath, who formed a prototype for doom metal with songs such as "Black Sabbath", "Children of the Grave", "Electric Funeral" and "Into the Void". During the first half of the 1980s, a number of bands from England (Pagan Altar, Witchfinder General), the United States (Pentagram, Saint Vitus, Trouble) and Sweden (Candlemass, Count Raven) defined doom metal as a distinct genre., Abigor is an Austrian atmospheric black metal band formed in 1993. They are named after an upper demon of war in Christian demonology., Metalcore is a broad fusion genre of extreme metal and hardcore punk. The word is a blend of the names of the two genres. Among other genres blending metal and hardcore, such as crust punk and grindcore, metalcore is noted for its use of breakdowns, which are slow, intense passages that are conducive to moshing. Pioneering metalcore bandssuch as Integrity, Earth Crisis and Converge, all of which had formed by 1990are described as leaning more toward hardcore, with their style sometimes being called metallic hardcore, whereas later bandssuch as Killswitch Engage, All That Remains, As I Lay Dying, Bullet for My Valentine, and Parkway Drive are described as leaning more towards metal. Pantera (who influenced Trivium, Atreyu, Bleeding Through and Unearth) and Sepultura have been particularly influential to the development of metalcore in the 2000s, which saw many bands in the genre achieve considerable commercial success., Death metal is an extreme subgenre of heavy metal music. It typically employs heavily distorted and low-tuned guitars, played with techniques such as palm muting and tremolo picking, deep growling vocals and screams, aggressive, powerful drumming featuring double kick or blast beat techniques, minor keys or atonality, abrupt tempo, key, and time signature changes and chromatic chord progressions. The lyrical themes of death metal may invoke slasher film-stylized violence, religion (sometimes Satanism), occultism, Lovecraftian horror, nature, mysticism, mythology, philosophy, science fiction, and politics, and they may describe extreme acts, including mutilation, dissection, torture, rape, cannibalism, and necrophilia., Vintersorg ("Winter Sorrow" in English) is a Swedish band from Skelleftea, formed in 1994 under the name Vargatron (Wolfthrone in English). Musically, Vintersorg has covered a wide number of heavy metal genres; while the band is mostly rooted in extreme metal styles, particularly black metal and Viking/folk metal, it has also expanded into progressive metal and avant-garde metal. Lyrically, the band deals with topics on fantasy, mythology, nature, the cosmos, and metaphysics. Vintersorg means "Winter Sorrow," but the name was taken from The Legend of the Ice People series by Margit Sandemo, where the character Vintersorg is the son of a great pagan leader., The Sins of Thy Beloved was a Death-doom/gothic metal band from Bryne, Norway, founded in 1996., Falkenbach is a viking metal group from Germany that is signed to "Prophecy Productions". The name means ""Falconbrook"" in German. The one permanent member is Vratyas Vakyas (real name Markus Tummers). They are one of the very first Viking metal bands, starting in 1989, with their first release that same year., Folk metal is a fusion genre of heavy metal music and traditional folk music that developed in Europe during the 1990s. It is characterised by the widespread use of folk instruments and, to a lesser extent, traditional singing styles (for example, Dutch Heidevolk, Danish Sylvatica and Spanish Stone of Erech). It also sometimes features soft instrumentation influenced by folk rock., Monster Magnet is an American stoner rock band. Hailing from Red Bank, New Jersey, the group was founded by Dave Wyndorf (vocals and guitar), John McBain (guitar) and Tim Cronin (vocals and drums). The band first went by the names "Dog of Mystery", "Airport 75", "Triple Bad Acid" and "King Fuzz" before finally settling on "Monster Magnet", taken from the name of a 1960s toy made by Wham-O, which Wyndorf liked when he was a child.<ref name="http://www.monstermagnet.net/bio.htm"></ref>, Death-doom is an extreme subgenre of heavy metal. It combines the slow tempos and pessimistic or depressive mood of doom metal with the deep growling vocals and double kick drumming of death metal. The genre emerged in the mid-1980s and gained a certain amount of popularity during the 1990s, but had become less common by the turn of the 21st century. In turn, death/doom gave rise to the closely related genre of funeral doom as well as to the more melodic and romantic gothic metal., Napalm Records is an Austrian independent record label focused on heavy metal and hard rock. Originally, Napalm focused mainly on black metal bands such as Abigor and Summoning and folk metal bands such as Falkenbach and Vintersorg. Later on, the label expanded its roster by adding gothic metal, symphonic metal, power metal, doom metal, and metalcore bands, as well as stoner rock acts Monster Magnet, Karma to Burn, and Brant Bjork. Napalm has its own publishing house named Iron Avantgarde Publishing., Stoner rock or stoner metal is a musical subgenre which combines elements of heavy metal, psychedelic rock, acid rock, doom metal, and blues rock. The term desert rock is often used interchangeably with the term "stoner rock" to describe this genre; however, not all stoner rock bands would fall under the descriptor of "desert rock." Stoner rock is typically slow-to-mid tempo and features a heavily distorted, groove laden bass-heavy sound, melodic vocals, and "retro" production. The genre emerged during the early-1990s and was pioneered foremost by the Californian bands Kyuss and Sleep., Hard rock is a loosely defined subgenre of rock music that began in the mid-1960s, with the garage, psychedelic and blues rock movements. It is typified by a heavy use of aggressive vocals, distorted electric guitars, bass guitar, drums, and often accompanied with pianos and keyboards., Subject: lake of sorrow, Relation: genre, Options: (A) acid rock (B) atonality (C) black metal (D) child (E) classical music (F) crust punk (G) death metal (H) doom metal (I) extreme metal (J) fantasy (K) folk metal (L) fusion (M) gothic fiction (N) gothic metal (O) gothic rock (P) grindcore (Q) hard rock (R) hardcore punk (S) heavy metal (T) instrumental (U) legend (V) literature (W) lovecraftian horror (X) march (Y) metalcore (Z) music ([) musical (\) mystery (]) opera (^) orchestra (_) politics (') power metal (a) progressive metal (b) prophecy (c) religion (d) rock (e) romantic (f) science (g) science fiction (h) song (i) speed metal (j) symphonic metal (k) symphony (l) terror (m) viking metal (n) war
