Question: In what country was Lost Gravity manufactured?
Context: Gravity Studios is a recording studio in Chicago, Illinois founded in 1993 by Doug McBride.  Starting with the single "Seether" by local band Veruca Salt, Gravity has hosted bands such as the Plain White T’s, Silversun Pickups, and Fall Out Boy.  An adjacent mastering studio, Gravity Mastering, has been used by bands and producers throughout the country. Lost Gravity is a steel roller coaster located at Walibi Holland in Biddinghuizen, Flevoland, the Netherlands.  It was manufactured by Mack Rides and constructed by RCS GmbH.  It opened to the public on 24 March 2016. The tallest dams in China are some of the tallest dams in the world.  Nearly 22,000 dams over 15 m in height – about half the world's total – have been constructed in China since the 1950s.  Many of the tallest are located in the southwestern part of the country (Guizhou, Sichuan, Yunnan) on rivers such as the Mekong, the Yangtze, and its upper stretch (Jinsha River) and tributaries (Yalong, Dadu, Min and Wu).  The Yellow River in the western part of the country also hosts several among the tallest.  Purposes for these high structures include flood control, irrigation and, predominantly, hydroelectric power.  While beneficial, many throughout the country have been criticized for their effects on the environment, displacement of locals and effect on transboundary river flows.  Currently, the country's and world's tallest, Jinping-I Dam, an arch dam 305 m high, is located in Sichuan.  The tallest embankment dam in China is the 261 m Nuozhadu Dam in Yunnan.  The country's highest gravity dam is Longtan Dam at 216.2 m , which can be found in Guangxi.  At 233 m , Shuibuya Dam in Hubei is the world's tallest concrete-face rock-fill dam.  In Sichuan, the government is constructing the 312 m tall Shuangjiangkou Dam which, when complete, will become the world's tallest dam. The Samsung SGH-T669 is a 3G-capable mobile phone manufactured by Samsung.  In the US it is also called the Samsung Gravity T; in Canada, the Samsung Gravity Touch. A swell, in the context of an ocean, sea or lake, is a series of mechanical waves that propagate along the interface between water and air and so they are often referred to as surface gravity waves.  These series of surface gravity waves are not generated by the immediate local wind, instead by distant weather systems, where wind blows for a duration of time over a fetch of water.  This is the primary definition of a swell as opposed to a locally generated wind wave, which is still under the influence of the mechanisms that created it e.g. wind blowing over a puddle.  More generally, a swell consists of wind-generated waves that are not—or are hardly—affected by the local wind at that time.  Swell waves often have a long wavelength but this varies due to the size, strength and duration of the weather system responsible for the swell and the size of the water body e.g. wavelengths are rarely more than 150 m in the Mediterranean .  Swell wavelength, also, varies from event to event.  Occasionally, swells which are longer than 700 m occur as a result of the most severe storms.  Swells have a narrower range of frequencies and directions than locally generated wind waves, because swell waves have dispersed from their generation area, have dissipated and therefore lost an amount of randomness, taking on a more defined shape and direction.  Swell direction is the direction from which the swell is coming.  It is measured in degrees (as on a compass), and often referred to in general directions, such as a NNW or SW swell. Lost Lander is an indie rock project founded by Matt Sheehy, touring multi-instrumentalist for Ramona Falls and EL VY, and former member of the duo Gravity & Henry.  The band's name is taken from a dream Sheehy's mother had about a place where she spent part of her childhood named Lost Land Lake. The Honda CMX450 "Rebel" was a motorcycle manufactured by Honda for model years 1986 and 1987.  In contrast to the Rebel 250 250cc cruiser, it has a 450cc engine.  The introduction of the Rebel 250 and 450 has been cited as a way for Honda to attract female riders, new to motorcycling, due to these bikes' low seat heights, low center of gravity, and overall ease of handling; however, the September 1985 issue of Motorcyclist magazine, when the Rebel was first introduced, states "by targeting the bike to a young audience, such as those who watch MTV, Honda hopes to attract newcomers and expand the motorcycle market ... Honda is not marketing this motorcycle as a woman's bike". Lost Gravity are a rock band formed in 2007 by Breno Val in London, England.  The band are known for their powerful guitar riffs, great vocal melodies and groovy drums.  Their main influences are AC/DC, Alice in Chains and Metallica. Mack Rides GmbH & Co KG, also known simply as Mack Rides, is a German company that designs and constructs amusement rides.  Mack Rides in headquartered in Waldkirch, Baden-Württemberg, Germany.

The family that owns Mack Rides also owns Europa-Park. "Sweet Thing" is a song co-written and recorded by Australian country music singer Keith Urban.  It was released on 3 November 2008 as the first single from his 2009 album "Defying Gravity".  It made its debut on the Hot Country Songs charts at number 30, becoming Urban's nineteenth Top 40 country hit, and on the chart week of 14 March 2009, it became his tenth number 1 single.  This song also went on to win his third win for 2010 Grammy Award for Best Male Country Vocal Performance in 2010.  This is Keith's first Top 40 hit on the Pop chart since Once in a Lifetime in 2006 and first Top 30 hit on the Pop chart since You'll Think of Me in 2004.  The song was written by Urban and Monty Powell.
