Problem: Given the question: Information:  - A seismogram is a graph output by a seismograph. It is a record of the ground motion at a measuring station as a function of time. Seismograms typically record motions in three cartesian axes (x, y, and z), with the z axis perpendicular to the Earth's surface and the x- and y- axes parallel to the surface. The energy measured in a seismogram may result from an earthquake or from some other source, such as an explosion. Seismograms can record lots of things, and record many little waves, called microseisms. These tiny microseisms can be caused by heavy traffic near the seismograph, waves hitting a beach, the wind, and any number of other ordinary things that cause some shaking of the seismograph.  Historically, seismograms were recorded on paper attached to rotating drums. Some used pens on ordinary paper, while others used light beams to expose photosensitive paper. Today, practically all seismograms are recorded digitally to make analysis by computer easier. Some drum seismometers are still found, especially when used for public display. Seismograms are essential for finding the location and magnitude of earthquakes.  - An explosion is a rapid increase in volume and release of energy in an extreme manner, usually with the generation of high temperatures and the release of gases. Supersonic explosions created by high explosives are known as detonations and travel via supersonic shock waves. Subsonic explosions are created by low explosives through a slower burning process known as deflagration. When caused by a man-made device such as an exploding rocket or firework, the audible component of an explosion is referred to as its "report" (which can also be used as a verb, e.g., "the rocket reported loudly upon impact".)  - A seismic source is a device that generates controlled seismic energy used to perform both reflection and refraction seismic surveys. A seismic source can be simple, such as dynamite, or it can use more sophisticated technology, such as a specialized air gun. Seismic sources can provide single pulses or continuous sweeps of energy, generating seismic waves, which travel through a medium such as water or layers of rocks. Some of the waves then reflect and refract and are recorded by receivers, such as geophones or hydrophones.  - Geology (from the Ancient Greek , "g", i.e. "earth" and -o, "-logia", i.e. "study of, discourse") is an earth science comprising the study of solid Earth, the rocks of which it is composed, and the processes by which they change. Geology can also refer generally to the study of the solid features of any terrestrial planet (such as the geology of the Moon or Mars).  - Bernard A. Chouet ( born 14 October 1945 ) is a geophysicist who specializes in volcanic seismology . He discovered that volcanic eruptions could be predicted by observing the frequency of certain seismic waves that are generated by volcanoes .  - Seismology (from Ancient Greek  ("seismós") meaning "earthquake" and - ("-logía") meaning "study of") is the scientific study of earthquakes and the propagation of elastic waves through the Earth or through other planet-like bodies. The field also includes studies of earthquake environmental effects such as tsunamis as well as diverse seismic sources such as volcanic, tectonic, oceanic, atmospheric, and artificial processes such as explosions. A related field that uses geology to infer information regarding past earthquakes is paleoseismology. A recording of earth motion as a function of time is called a seismogram. A seismologist is a scientist who does research in seismology.    What entity does 'bernard chouet' has the relation 'occupation' with?
++++++++++++++++++++++++++++++++
The answer is:
seismologist


Problem: Given the question: Information:  - Willy Planckaert ( born 5 April 1944 in Nevele ) is a Belgian former road bicycle racer . His brothers Eddy and Walter Planckaert are also famous road bicycle racers . His son , Jo , was also a cyclist .  - Jo Planckaert (born 16 December 1970 in Deinze) is a former Belgian professional road bicycle racer. He is the son of former professional road bicycle racer Willy Planckaert, brother of famous road bicycle racers Eddy and Walter Planckaert.  - Walter Planckaert (born 8 April 1948 in Nevele) is a Belgian former professional road racing cyclist. He is the younger brother of Willy Planckaert, the older brother of Eddy Planckaert, and the uncle of Jo Planckaert. He had 74 victories in his professional career. After retiring from riding, he commenced a long career in team management, working for the Panasonic, Novemail-Histor, Palmans, Lotto-Adecco and Chocolade Jacques teams.  - Eddy Planckaert (b. Nevele, 22 September 1958) is a former professional road racing cyclist from Belgium. In 1988, Planckaert enjoyed perhaps his best year by capturing the green jersey (points competition) at the 1988 Tour de France and winning the Tour of Flanders. In 1990, he won ParisRoubaix, his second "monumental classic", with the closest finish in the race's history beating Canadian Steve Bauer by less than a cm. More than 10 years after his cycling career, the former racer got back into the public eye with a long running reality TV show about his family life, on Vtm.    What entity does 'willy planckaert' has the relation 'child' with?
