Q: Information: - Bodyboarding is a water sport in which the surfer rides a bodyboard on the crest, face, and curl of a wave which is carrying the surfer towards the shore. Bodyboarding is also referred to as "Boogieboarding" due to the invention of the "Boogie Board" by Tom Morey. The average bodyboarding consists of a short, rectangular piece of hydrodynamic foam. Bodyboarders typically use swim fins for additional propulsion and control while riding a breaking wave. - A swimming pool, swimming bath, wading pool, or paddling pool is a structure designed to hold water to enable swimming or other leisure activities. Pools can be built into the ground (in ground pools) or built above ground (as a freestanding construction or as part of a building or other larger structure), and are also a standard feature aboard oceanliners and cruise ships. In-ground pools are most commonly constructed from materials such as concrete, natural stone, metal, plastic or fiberglass, and can be of a custom size and shape or built to a standardised size, the largest of which is the Olympic-size swimming pool. - An amusement park (sometimes referred to as a funfair) or theme park is a group of entertainment attractions, rides, and other events in a location for the enjoyment of large numbers of people. Amusement parks have a fixed location, as opposed to travelling funfairs and traveling carnivals, and are more elaborate than simple city parks or playgrounds, usually providing attractions meant to cater specifically to certain age groups, as well as some that are aimed towards all ages. Theme parks, a specific type of amusement park, are usually much more intricately themed to a certain subject or group of subjects than normal amusement parks. - A water slide (also referred to as "flumes", "water chutes", or "hydroslides") is a type of slide designed for warm-weather or indoor recreational use at water parks. Water slides differ in their riding method and therefore size. Some slides require riders to sit directly on the slide, or on a raft or tube designed to be used with the slide. - Lost Island Water Park is a water park located in Waterloo , Iowa . It is open from May to October each year . - Surfing is a surface water sport in which the wave rider, referred to as a surfer, rides on the forward or deep face of a moving wave, which is usually carrying the surfer towards the shore. Waves suitable for surfing are primarily found in the ocean, but can also be found in lakes or in rivers in the form of a standing wave or tidal bore. However, surfers can also utilize artificial waves such as those from boat wakes and the waves created in artificial wave pools. - Bathing is the washing of the body with a fluid, usually water or an aqueous solution, or the immersion of the body in water. It may be practiced for personal hygiene, religious ritual or therapeutic purposes. By analogy, especially as a recreational activity, the term is also applied to sun bathing and sea bathing. - A wave pool is a swimming pool in which there are artificially generated, reasonably large waves, similar to those of the ocean. Wave pools are often a major feature of water parks. Siam Park City Water Park in Thailand is home to the world's largest wave pool certified by Guinness World Records, and Siam Park (Tenerife) in Spain is home to the biggest man made waves (about 3 meters (9.8 ft)) in the world. - A water park or waterpark is an amusement park that features water play areas, such as swimming pools, water slides, splash pads, spraygrounds (water playgrounds), lazy rivers, or other recreational bathing, swimming, and barefooting environments. Water parks in more current states of development may also be equipped with some type of artificial surfing or bodyboarding environment such as a wave pool or FlowRider. - A splash pad or spray pool is a recreation area, often in a public park, for water play that has little or no standing water. This is said to eliminate the need for lifeguards or other supervision, as there is little risk of drowning. Splash pads have existed in the commercial industry for decades. - A lazy river is a water ride found in water parks, hotels, resorts, and recreation centers, which usually consists of a shallow (2ft. to 3ft.) pool that flows similarly to a river. There is generally a slow current, usually just enough to allow guests to gently ride along lying on rafts. There may also be scenic elements added, such as small waterfalls on the edge of the river. Some lead into wave pools, while some just go around in circles. Given the information, choose the subject and object entities that have the relation of 'instance of'.

Q: Information: - Grindcore is an extreme genre of music that originated in the early to mid-1980s. It draws inspiration from some of the most abrasive-sounding genres including hardcore punk, thrash metal, crust punk, industrial, death metal and noise rock. Grindcore is characterized by a noise-filled sound that uses heavily distorted, down-tuned guitars, grinding overdriven bass, high speed tempo, blast beats, and vocals which consist of growls and high-pitched shrieks. Early groups like Napalm Death are credited with laying the groundwork for the style. It is most prevalent today in North America and Europe, with popular contributors such as Brutal Truth and Nasum. Lyrical themes range from a primary focus on social and political concerns, to gory subject matter and black humor. - 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. - Doug Williams is an American bassist . He played for death metal bands Origin and Cephalic Carnage . He is playing with the Miami , Florida based metal band Solstice . - Cephalic Carnage is an American grindcore band formed in 1992 in Denver, Colorado. The band comprises vocalist Lenzig Leal, guitarists Steve Goldberg and Brian Hopp, drummer John Merryman and bassist Nick Schendzielos. Cephalic Carnage has released six studio albums and toured in North America, Europe and Japan. - Heavy metal (or simply metal) is a genre of rock music that developed in the late 1960s and early 1970s, largely in the United Kingdom and the United States. With roots in blues rock and psychedelic/acid rock, the bands that created heavy metal developed a thick, massive sound, characterized by highly amplified distortion, extended guitar solos, emphatic beats, and overall loudness. Heavy metal lyrics and performance styles are sometimes associated with aggression and machismo. - A blast beat is a drum beat that originated in hardcore punk and grindcore, and is often associated with extreme metal and more recently black metal and thrash. It is utilised by many different styles of metal. In Adam MacGregor's definition, "the blast-beat generally comprises a repeated, sixteenth-note figure played at a very fast tempo, and divided uniformly among the bass drum, snare, and ride, crash, or hi-hat cymbal." Blast beats have been described as, "maniacal percussive explosions, less about rhythm per se than sheer sonic violence".
