Question: The answer to the question: What is a Grade I listed building? is inside the article: Wells Cathedral is an Anglican cathedral in Wells, Somerset, England, dedicated to St Andrew the Apostle and seat of the Bishop of Bath and Wells, whose throne or cathedra it holds as mother church of the diocese. Built between 1175 and 1490 to replace an earlier church on the site since 705, it is moderately sized for an English cathedral. Its broad west front and large central tower are dominant features in the city and countryside. It has been called "unquestionably one of the most beautiful" and "most poetic" of English cathedrals. Its Gothic architecture is mostly in the Early English style of the late 12thearly 13th centuries, lacking the Romanesque work that survives in many other cathedrals. Building began about 1175 at the east end with the choir. Historian John Harvey sees it as Europe's first truly Gothic structure, breaking with the last constraints of Romanesque. The stonework of its pointed arcades and fluted piers bears pronounced mouldings and carved capitals in a foliate, "stiff leaf" style. Its Early English front with 300 sculpted figures, is described as a "supreme triumph of the combined plastic arts in England". The east end retains a rare amount of ancient stained glass. Unlike many cathedrals of monastic foundation, Wells has many surviving secular buildings linked to its chapter of secular canons, including the Bishop's Palace and the 15th-century residential Vicars' Close. The cathedral is a Grade I listed building., can you guess it ?
Answer: Wells Cathedral

Question: The answer to the question: What equipment is prone to erroneous results? is inside the article: Established on Kilauea in 1912, the Hawaiian Volcano Observatory (HVO), presently a branch of the United States Geological Survey, is the primary organization associated with the monitoring, observance, and study of Hawaiian volcanoes. Thomas A. Jaggar, the observatory's founder, attempted a summit expedition to Mauna Loa to observe its 1914 eruption, but was rebuffed by the arduous trek required (see Ascents). After soliciting help from Lorrin A. Thurston, in 1915 he was able to persuade the US Army to construct a "simple route to the summit" for public and scientific use, a project completed in December of that year; the Observatory has maintained a presence on the volcano ever since.Eruptions on Mauna Loa are almost always preceded and accompanied by prolonged episodes of seismic activity, the monitoring of which was the primary and often only warning mechanism in the past and which remains viable today. Seismic stations have been maintained on Hawaii since the Observatory's inception, but these were concentrated primarily on Kilauea, with coverage on Mauna Loa improving only slowly through the 20th century. Following the invention of modern monitoring equipment, the backbone of the present-day monitoring system was installed on the volcano in the 1970s. Mauna Loa's July 1975 eruption was forewarned by more than a year of seismic unrest, with the HVO issuing warnings to the general public from late 1974; the 1984 eruption was similarly preceded by as much as three years of unusually high seismic activity, with volcanologists predicting an eruption within two years in 1983.The modern monitoring system on Mauna Loa is constituted not only by its locally seismic network but also of a large number of GPS stations, tiltmeters, and strainmeters that have been anchored on the volcano to monitor ground deformation due to swelling in Mauna Loa's subterranean magma chamber, which presents a more complete picture of the events proceeding eruptive activity. The GPS network is the most durable and wide-ranging of the..., can you guess it ?
Answer: the tiltmeters

Question: The answer to the question: What is the name of the man who abandoned Julie and Ellen? is inside the article: Julie Cullen is a young divorced parent, on her own for the past four years since her husband abandoned her and their daughter, Ellen, only a year old at the time. At work, Julie, who is white, meets Frank Richards, who is black, and the two strike up a friendship that blossoms into a romance. Their relationship is strained by the racial prejudices of many around them, including Frank's parents, William and Martha, who oppose the pairing. But ultimately Frank and Julie decide to persevere through such difficulties. They marry, and Julie and Ellen move in with Frank and his parents. Ellen's arrival immediately softens Martha's heart, but William remains cool toward Julie, steadfast in his belief that Frank and Julie's marriage is a foolish endeavor. His attitude changes only when Frank and Julie have a son together. When William first holds his new grandson, he loses any remaining animosity and the household becomes a happy one for all. Eventually, Julie's ex-husband, Joe, returns, seeking to establish a visitation relationship with Ellen. However, when he finds that Julie's and Ellen's new family is black, he finds this unacceptable and petitions the court for legal custody of Ellen. Frank's lawyer tells him that Joe is likely to win. Agreeing with the lawyer's analysis, William advises Frank to take Julie and the children and flee the state. Frank, however, decides to stay and fight the case in court. When Julie appeals to Joe directly, it only angers him, and he even briefly attempts to force himself on Julie physically. When Frank learns what has happened, he is intensely frustrated by his inability to defend his wife by directly confronting Joe, since he knows that if he does, that will be the end of whatever small chance he and Julie have of winning the custody case., can you guess it ?
Answer:
Joe
