Question Description
Read the passage carefully and answer the questions given at the end.Pigeon photography is an aerial photography technique invented in 1907 by the German apothecary Julius Neubronner, who also used pigeons to deliver medications. A homing pigeon was fitted with an aluminium breast harness to which a lightweight time-delayed miniature camera could be attached. Neubronner's German patent application was initially rejected, but was granted in December 1908 after he produced authenticated photographs taken by his pigeons. He publicized the technique at the 1909 Dresden International Photographic Exhibition, and sold some images as postcards at the Frankfurt International Aviation Exhibition and at the 1910 and 1911 Paris Air Shows.Initially, the military potential of pigeon photography for aerial reconnaissance appeared attractive. Battlefield tests in the First World War provided encouraging results, but the ancillary technology of mobile dovecotes for messenger pigeons had the greatest impact. Owing to the rapid perfection of aviation during the war, military interest in pigeon photography faded and Neubronner abandoned his experiments. The idea was briefly resurrected in the 1930s by a Swiss clockmaker, and reportedly also by the German and French militaries. Although war pigeons were deployed extensively during the Second World War, it is unclear to what extent, if any, birds were involved in aerial reconnaissance. The United States Central Intelligence Agency (CIA) later developed a battery-powered camera designed for espionage pigeon photography; details of its use remain classified.The construction of sufficiently small and light cameras with a timer mechanism, and the training and handling of the birds to carry the necessary loads, presented major challenges, as did the limited control over the pigeons' position, orientation and speed when the photographs were being taken. In 2004, the British Broadcasting Corporation (BBC) used miniature television cameras attached to falcons and goshawks to obtain live footage, and today some researchers, enthusiasts and artists similarly deploy crittercams with various species of animals.The first aerial photographs were taken in 1858 by the balloonist Nadar; in 1860 James Wallace Black took the oldest surviving aerial photographs, also from a balloon. As photographic techniques made further progress, at the end of the 19th century some pioneers placed cameras in unmanned flying objects. In the 1880s, Arthur Batut experimented with kite aerial photography. Many others followed him, and high-quality photographs of Boston taken with this method by William Abner Eddy in 1896 became famous. AmedeeDenisse equipped a rocket with a camera and a parachute in 1888, and Alfred Nobel also used rocket photography in 1897.Homing pigeons were used extensively in the 19th and early 20th centuries, both for civil pigeon post and as war pigeons. In the Franco-Prussian War of 1870, the famous pigeon post of Paris carried up to 50,000 microfilmed telegrams per pigeon flight from Tours into the besieged capital. Altogether 150,000 individual private telegrams and state dispatches were delivered. In an 1889 experiment of the Imperial Russian Technical Society at Saint Petersburg, the chief of the Russian balloon corps took aerial photographs from a balloon and sent the developed collodion film negatives to the ground by pigeon post.In 1903 Julius Neubronner, an apothecary in the German town of Kronberg near Frankfurt, resumed a practice begun by his father half a century earlier and received prescriptions from a sanatorium in nearby Falkenstein via pigeon post. (The pigeon post was discontinued after three years when the sanatorium was closed.) He delivered urgent medications up to 75 grams (2.6 oz) by the same method, and positioned some of his pigeons with his wholesaler in Frankfurt to profit from faster deliveries himself. When one of his pigeons lost its orientation in fog and mysteriously arrived, well-fed, four weeks late, Neubronner was inspired with the playful idea of equipping his pigeons with automatic cameras to trace their paths. This thought led him to merge his two hobbies into a new "double sport" combining carrier pigeon fancying with amateur photography. (Neubronner later learned that his pigeon had been in the custody of a restaurant chef in Wiesbaden.)After successfully testing a Ticka watch camera on a train and whilst riding a sled, Neubronner began the development of a light miniature camera that could be fitted to a pigeon's breast by means of a harness and an aluminum cuirass. Using wooden camera models which weighed 30 to 75 grams (1.1 to 2.6 oz), the pigeons were carefully trained for their load. To take an aerial photograph, Neubronner carried a pigeon to a location up to about 100 kilometres (60 mi) from its home, where it was equipped with a camera and released. The bird, keen to be relieved of its burden, would typically fly home on a direct route, at a height of 50 to 100 metres (160 to 330 ft).[10] A pneumatic system in the camera controlled the time delay before a photograph was taken. To accommodate the burdened pigeon, the dovecote had a spacious, elastic landing board and a large entry hole.According to Neubronner, there were a dozen different models of his camera. In 1907 he had sufficient success to apply for a patent. Initially his invention "Method of and Means for Taking Photographs of Landscapes from Above" was rejected by the German patent office as impossible, but after presentation of authenticated photographs the patent was granted in December 1908. (The rejection was based on a misconception about the carrying capacity of domestic pigeons). The technology became widely known through Neubronner's participation in the 1909 International Photographic Exhibition in Dresden and the 1909 International Aviation Exhibition in Frankfurt. Spectators in Dresden could watch the arrival of the pigeons, and the aerial photographs they brought back were turned into postcards. Neubronner's photographs won prizes in Dresden as well as at the 1910 and 1911 Paris Air Shows.Q. Identify the correct statement:a)The first patent application of Neubronner for Pigeon photography was rejected because the authorities believed that the carrying capacity of a domestic pigeon is not much to carry the camera and hence the concept is impossible.b)Pigeons equipped with cameras were extremely useful in the Franco-Prussian War of 1870.c)The pigeon post used by Julius Neubronner was discontinued because one of his pigeons lost its orientation in fog.d)Neubronner abandoned his experiments on military potential of pigeon photography because the results were not promising.Correct answer is option 'A'.

Altogether 150,000 individual private telegrams and state dispatches were delivered. In an 1889 experiment of the Imperial Russian Technical Society at Saint Petersburg, the chief of the Russian balloon corps took aerial photographs from a balloon and sent the developed collodion film negatives to the ground by pigeon post.In 1903 Julius Neubronner, an apothecary in the German town of Kronberg near Frankfurt, resumed a practice begun by his father half a century earlier and received prescriptions from a sanatorium in nearby Falkenstein via pigeon post. (The pigeon post was discontinued after three years when the sanatorium was closed.) He delivered urgent medications up to 75 grams (2.6 oz) by the same method, and positioned some of his pigeons with his wholesaler in Frankfurt to profit from faster deliveries himself. When one of his pigeons lost its orientation in fog and mysteriously arrived, well-fed, four weeks late, Neubronner was inspired with the playful idea of equipping his pigeons with automatic cameras to trace their paths. This thought led him to merge his two hobbies into a new "double sport" combining carrier pigeon fancying with amateur photography. (Neubronner later learned that his pigeon had been in the custody of a restaurant chef in Wiesbaden.)After successfully testing a Ticka watch camera on a train and whilst riding a sled, Neubronner began the development of a light miniature camera that could be fitted to a pigeon's breast by means of a harness and an aluminum cuirass. Using wooden camera models which weighed 30 to 75 grams (1.1 to 2.6 oz), the pigeons were carefully trained for their load. To take an aerial photograph, Neubronner carried a pigeon to a location up to about 100 kilometres (60 mi) from its home, where it was equipped with a camera and released. The bird, keen to be relieved of its burden, would typically fly home on a direct route, at a height of 50 to 100 metres (160 to 330 ft).[10] A pneumatic system in the camera controlled the time delay before a photograph was taken. To accommodate the burdened pigeon, the dovecote had a spacious, elastic landing board and a large entry hole.According to Neubronner, there were a dozen different models of his camera. In 1907 he had sufficient success to apply for a patent. Initially his invention "Method of and Means for Taking Photographs of Landscapes from Above" was rejected by the German patent office as impossible, but after presentation of authenticated photographs the patent was granted in December 1908. (The rejection was based on a misconception about the carrying capacity of domestic pigeons). The technology became widely known through Neubronner's participation in the 1909 International Photographic Exhibition in Dresden and the 1909 International Aviation Exhibition in Frankfurt. Spectators in Dresden could watch the arrival of the pigeons, and the aerial photographs they brought back were turned into postcards. Neubronner's photographs won prizes in Dresden as well as at the 1910 and 1911 Paris Air Shows.Q. Identify the correct statement:a)The first patent application of Neubronner for Pigeon photography was rejected because the authorities believed that the carrying capacity of a domestic pigeon is not much to carry the camera and hence the concept is impossible.b)Pigeons equipped with cameras were extremely useful in the Franco-Prussian War of 1870.c)The pigeon post used by Julius Neubronner was discontinued because one of his pigeons lost its orientation in fog.d)Neubronner abandoned his experiments on military potential of pigeon photography because the results were not promising.Correct answer is option 'A'. Can you explain this answer?, a detailed solution for Read the passage carefully and answer the questions given at the end.Pigeon photography is an aerial photography technique invented in 1907 by the German apothecary Julius Neubronner, who also used pigeons to deliver medications. A homing pigeon was fitted with an aluminium breast harness to which a lightweight time-delayed miniature camera could be attached. Neubronner's German patent application was initially rejected, but was granted in December 1908 after he produced authenticated photographs taken by his pigeons. He publicized the technique at the 1909 Dresden International Photographic Exhibition, and sold some images as postcards at the Frankfurt International Aviation Exhibition and at the 1910 and 1911 Paris Air Shows.Initially, the military potential of pigeon photography for aerial reconnaissance appeared attractive. Battlefield tests in the First World War provided encouraging results, but the ancillary technology of mobile dovecotes for messenger pigeons had the greatest impact. Owing to the rapid perfection of aviation during the war, military interest in pigeon photography faded and Neubronner abandoned his experiments. The idea was briefly resurrected in the 1930s by a Swiss clockmaker, and reportedly also by the German and French militaries. Although war pigeons were deployed extensively during the Second World War, it is unclear to what extent, if any, birds were involved in aerial reconnaissance. The United States Central Intelligence Agency (CIA) later developed a battery-powered camera designed for espionage pigeon photography; details of its use remain classified.The construction of sufficiently small and light cameras with a timer mechanism, and the training and handling of the birds to carry the necessary loads, presented major challenges, as did the limited control over the pigeons' position, orientation and speed when the photographs were being taken. In 2004, the British Broadcasting Corporation (BBC) used miniature television cameras attached to falcons and goshawks to obtain live footage, and today some researchers, enthusiasts and artists similarly deploy crittercams with various species of animals.The first aerial photographs were taken in 1858 by the balloonist Nadar; in 1860 James Wallace Black took the oldest surviving aerial photographs, also from a balloon. As photographic techniques made further progress, at the end of the 19th century some pioneers placed cameras in unmanned flying objects. In the 1880s, Arthur Batut experimented with kite aerial photography.
