Question: I have a test where I am given the following article, what is an answer for the question: What is the name used when the sea draws back and leaves subtidal areas close to the shore exposed? ?  A tsunami is an unusual form of wave caused by an infrequent powerful event such as an underwater earthquake or landslide, a meteorite impact, a volcanic eruption or a collapse of land into the sea. These events can temporarily lift or lower the surface of the sea in the affected area, usually by a few feet. The potential energy of the displaced seawater is turned into kinetic energy, creating a shallow wave, a tsunami, radiating outwards at a velocity proportional to the square root of the depth of the water and which therefore travels much faster in the open ocean than on a continental shelf. In the deep open sea, tsunamis have wavelengths of around 80 to 300 miles (130 to 480 km), travel at speeds of over 600 miles per hour (970 km/hr) and usually have a height of less than three feet, so they often pass unnoticed at this stage. In contrast, ocean surface waves caused by winds have wavelengths of a few hundred feet, travel at up to 65 miles per hour (105 km/h) and are up to 45 feet (14 metres) high.A trigger event on the continental shelf may cause a local tsunami on the land side and a distant tsunami that travels out across the ocean. The energy of the wave is dissipated only gradually, but is spread out over the wave front, so as the wave radiates away from the source, the front gets longer and the average energy reduces, so distant shores will, on average, be hit by weaker waves. However, as the speed of the wave is controlled by the water depth, it does not travel at the same speed in all directions, and this affects the direction of the wave front - an effect known as refraction - which can focus the strength of the advancing tsunami on some areas and weaken it in others according to undersea topography. As a tsunami moves into shallower water its speed decreases, its wavelength shortens and its amplitude increases enormously, behaving in the same way as a wind-generated wave in shallow water, but on a vastly greater scale.  Either the trough or the crest of a tsunami can arrive at the coast first....
Answer: trough
[Q]: I have a test where I am given the following article, what is an answer for the question: What is the name of the person who persisted in his proposal of marriage, which was eventually accepted by Susana? ?  In 1947, Walton was presented with the Royal Philharmonic Society's Gold Medal. In the same year he accepted an invitation from the BBC to compose his first opera. He decided to base it on Chaucer's Troilus and Criseyde, but his preliminary work came to a halt in April 1948 when Alice Wimborne died. To take Walton's mind off his grief, the music publisher Leslie Boosey persuaded him to be a British delegate to a conference on copyright in Buenos Aires later that year.  While there, Walton met Susana Gil Passo (1926–2010), daughter of an Argentine lawyer. At 22 she was 24 years younger than Walton (Alice Wimborne had been 22 years his senior), and at first she ridiculed his romantic interest in her. He persisted, and she eventually accepted his proposal of marriage. The wedding was held in Buenos Aires in December 1948. From the start of their marriage, the couple spent half the year on the Italian island of Ischia, and by the mid-1950s they lived there permanently.Walton's last work of the 1940s was his music for Olivier's film of Hamlet (1948). After that, he focused his attentions on his opera Troilus and Cressida. On the advice of the BBC, he invited Christopher Hassall to write the libretto. This did not help Walton's relations with the Sitwells, each of whom thought he or she should have been asked to be his librettist. Work continued slowly over the next few years, with many breaks while Walton turned to other things. In 1950 he and Heifetz recorded the Violin Concerto for EMI. In 1951 Walton was knighted. In the same year, he prepared an authorised version of Façade, which had undergone many revisions since its premiere. In 1953, following the accession of Elizabeth II he was again called on to write a coronation march, Orb and Sceptre; he was also commissioned to write a choral setting of the Te Deum for the occasion.Troilus and Cressida was presented at Covent Garden on 3 December 1954. Its preparation was dogged by misfortunes. Olivier, originally scheduled to direct it, backed out, as did Henry...

input: Please answer the following: I have a test where I am given the following article, what is an answer for the question: What is the full name of the person who takes off, despite bad weather? ?  On May 19, 1927, after waiting for a week for the rain to stop on Long Island, New York, pilot Charles A. "Slim" Lindbergh tries to sleep in a hotel near Roosevelt Field, before his transatlantic flight from New York to Paris. His friend Frank Mahoney guards his hotel room door from reporters. Unable to sleep, Lindbergh reminisces about his time as an airmail pilot. Flying to Chicago in winter, "Slim" lands his old de Havilland biplane at a small airfield to refuel. Despite bad weather, he takes off, unaware that heavy snow has closed the Chicago landing field. Lindbergh bails out in a storm after running out of fuel. Recovering mail from his crashed DH-4, he continues to Chicago by train. A salesman tells him two airmen just died competing for the Orteig Prize for the first nonstop flight from New York City to Paris. Lindbergh calls Columbia Aircraft Corporation in New York from a small diner at the Lambert-St. Louis Flying Field. Quoted a price of $15,000 ($220,000 today) for a Bellanca high-wing monoplane, "Slim" lobbies St. Louis financiers with a plan to fly the Atlantic in 40 hours in a stripped-down, single-engine aircraft. The backers are excited by Lindbergh's vision and dub the venture Spirit of St. Louis. When the Bellanca deal falls apart because Columbia insists on selecting the pilot, Lindbergh approaches Ryan Aeronautical Company, a small manufacturer in San Diego, California. Frank Mahoney, the company's owner and president, promises to build a suitable monoplane in just 90 days. With Ryan's chief engineer Donald Hall, a design takes shape. To decrease weight, "Slim" refuses to install a radio or other heavy equipment, even a parachute, and plans to navigate by "dead reckoning". With no autopilot function Lindbergh cannot sleep during the flight. Workers at the factory agree to work around-the-clock to complete the monoplane in less than 90 days.

output:
Charles A. "Slim" Lindbergh
