Problem: Information: - An engine or motor is a machine designed to convert one form of energy into mechanical energy. Heat engines burn a fuel to create heat, which then creates a force. Electric motors convert electrical energy into mechanical motion; pneumatic motors use compressed air and clockwork motors in wind-up toys use elastic energy. In biological systems, molecular motors, like myosins in muscles, use chemical energy to create forces and eventually motion. - The de Havilland Gipsy is a British air-cooled four-cylinder in-line aircraft engine designed by Frank Halford in 1927 to replace the ADC Cirrus in the de Havilland DH.60 Moth light biplane. Initially developed as an upright 5litre (300cubic inch) capacity engine, later versions were designed to run inverted with increased capacity and power. - A biplane is a fixed-wing aircraft with two main wings stacked one above the other. The first powered, controlled aeroplane to fly, the Wright Flyer, used a biplane wing arrangement, as did many aircraft in the early years of aviation. While a biplane wing structure has a structural advantage over a monoplane, it produces more drag than a similar unbraced or cantilever monoplane wing. Improved structural techniques, better materials and the quest for greater speed made the biplane configuration obsolete for most purposes by the late 1930s. - The Alfa Romeo 110 was an Italian four cylinder air - cooled inverted inline engine for aircraft use , mainly for trainers and light aircraft . The Alfa Romeo 110 was based on the de Havilland Gipsy Major , with approximately 500 units produced . Derivatives of the 110 include the -1 , ter and Alfa Romeo 111 ( possibly a mis identification of the 110 - 1 ) . - An aircraft is a machine that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or by using the dynamic lift of an airfoil, or in a few cases the downward thrust from jet engines. - The de Havilland Gipsy Major or Gipsy IIIA is a four-cylinder, air-cooled, inline engine used in a variety of light aircraft produced in the 1930s, including the famous Tiger Moth biplane. Many Gipsy Major engines still power vintage aircraft types worldwide today. What entity does 'alfa romeo 110' has the relation 'subclass of' with?

A: aircraft engine

[Q]: Information: - Terry Date (born January 31, 1956) is an American record producer and engineer, specializing in the rock and metal genres. He is well known for his work with Overkill, Metal Church, Slipknot, Pantera, Soulfly, White Zombie, Deftones, Dark Angel, Dream Theater, Slayer, Soundgarden and Limp Bizkit. - Alternative metal (also known as alt-metal) is a rock music genre that infuses heavy metal with influences from alternative rock and other genres not normally associated with metal. Alternative metal bands are often characterized by heavily downtuned, mid-paced guitar riffs, a mixture of accessible melodic vocals and harsh vocals and sometimes unconventional sounds within other heavy metal styles. The term has been in use since the 1980s, although it came into prominence in the 1990s. - Rock music is a genre of popular music that originated as "rock and roll" in the United States in the 1950s, and developed into a range of different styles in the 1960s and later, particularly in the United Kingdom and the United States. It has its roots in 1940s' and 1950s' rock and roll, itself heavily influenced by blues, rhythm and blues and country music. Rock music also drew strongly on a number of other genres such as electric blues and folk, and incorporated influences from jazz, classical and other musical sources. - Saturday Night Wrist is the fifth studio album by the American alternative metal band Deftones. It was released by Maverick Records on October 31, 2006. Despite early contributions that were later scrapped, "Saturday Night Wrist" marked the departure of mainstay Deftones producer Terry Date. It was their last released album to feature bass player Chi Cheng before his accident in 2008 (although an additional album with Cheng, "Eros", was in production at the time of the accident) and subsequent death in 2013. - '' Hole in the Earth '' is a song by the American alternative metal band Deftones . The song was released as the first single from their fifth album , Saturday Night Wrist , and appeared as the album 's opening track . - Alternative rock (also called alternative music, alt-rock or simply alternative) is a genre of rock music that emerged from the independent music underground of the 1980s and became widely popular in the 1990s and 2000s. In this instance, the word "alternative" refers to the genre's distinction from mainstream rock music. The term's original meaning was broader, referring to a generation of musicians unified by their collective debt to either the musical style or simply the independent, D.I.Y. ethos of punk rock, which in the late 1970s laid the groundwork for alternative music. At times, "alternative" has been used as a catch-all description for music from underground rock artists that receives mainstream recognition, or for any music, whether rock or not, that is seen to be descended from punk rock (including some examples of punk itself, as well as new wave, and post-punk).
