In this task, you're given a question, along with a context passage. The passage will not have a direct answer to the question, but can include some information and a clue for the answer. Assuming you can only obtain information about one entity in the passage, your job is to determine whether information from the passage can be used to answer the question. Indicate your choice as `a` for Yes or `b` for No.

Input: Consider Input: Question: What is the scientific name for studying why there are foreign materials in a bee's honey? Passage:Anemophilous pollen grains are light and non-sticky, so that they can be transported by air currents. They are typically in diameter, although the pollen grains of Pinus species can be much larger and much less dense. Anemophilous plants possess well-exposed stamens so that the pollens are exposed to wind currents and also have large and feathery stigma to easily trap airborne pollen grains. Pollen from anemophilous plants tends to be smaller and lighter than pollen from entomophilous ones, with very low nutritional value to insects. However, insects sometimes gather pollen from staminate anemophilous flowers at times when higher-protein pollens from entomophilous flowers are scarce. Anemophilous pollens may also be inadvertently captured by bees' electrostatic field. This may explain why, though bees are not observed to visit ragweed flowers, its pollen is often found in honey made during the ragweed floral bloom. Other flowers that are generally anemophilous are observed to be actively worked by bees, with solitary bees often visiting grass flowers, and the larger honeybees and bumblebees frequently gathering pollen from corn tassels and other grains.

Input: Consider Input: Question: What place did the person who beat Cucelli at Eimbledon in 1947 end up with? Passage:Giovanni Cucelli (born as Giovanni Kucel) (1916–1977) was an Italian tennis player. He played Davis Cup for Italy and formed a great doubles partnership with Marcello Del Bello. Because of World War 2, Cucelli was 30 by the time he made his Grand Slam debut at Wimbledon in 1947, where he lost in the third round to Jack Kramer. At Roland Garros (held just after Wimbledon) Cucelli beat veteran Jack Crawford and Robert Abdesselam before losing to defending champion Marcel Bernard in five sets in the quarter finals. At Roland Garros in 1948, Cucelli beat a young Frank Sedgman before losing to Frank Parker in the quarter finals. At Wimbledon Cucelli beat Jaroslav Drobny before losing to Tony Mottram in round three. At Roland Garros in 1949, Cucelli reached his third consecutive quarter final, where he lost to Budge Patty. At Wimbledon he beat Mottram before losing to Eric Sturgess in the last 16. At 1949 U. S. championships, Cucelli lost in round two to Sam Match. Cucelli lost in the last 16 of Roland Garros in 1950 to Patty. After early exits at the French and Wimbledon in 1951, Cucelli reached the last 16 at Roland Garros in 1952, where he lost to Ken McGregor. He lost early at Wimbledon to Mottram. Cucelli lost his first match at Roland Garros in 1953 to Rex Hartwig. In 1955 Cucelli turned professional. Cucelli won a lot of tournaments during his career: Italian Riviera championships and Alassio in 1939, Napoli and Barcelona Christmas tournament in 1941, St. Moritz, French-Switzerland championships and Milan international in 1946, Swiss championships, Villars, Montana-Vermala, Viareggio and Rapallo in 1947, Milan international, Napoli, Rapallo, Montecatini and Barcelona Christmas tournament in 1948, San Remo in 1949, Lugano, Istanbul, Venice and Lugano Lido tournament in 1950, San Pellegrino and Viareggio in 1951 and Cava De Tirreni in 1952. He was runner up at Monte Carlo in 1948 to Jozsef Asboth and 1949 to Parker and runner up at Rome in 1951 (where he beat Patty before losing to Drobny).

Input: Consider Input: Question: How many years had Arnstadt been married when he got divorced? Passage:In June 1949, Arnstadt registered for service with the Volkspolizei, the police force of the Soviet Occupation Zone, becoming an Anwärter der VP (police cadet) with the Kasernierte Volkspolizei in Gotha. In March 1950, Arnstadt was appointed to the German Border Police (Deutsche Grenzpolizei) in Dermbach, patrolling the Inner German border with West Germany. In 1952, Arnstadt failed his first attempt to become an officer at the police school in Sondershausen. In 1953, his marriage ended in divorce, with his two children Veronika and Uwe staying with the mother, and remarried shortly after. In 1954, Arnstadt passed his officer training at Sondershausen and was appointed the rank of Unterleutnant, and the following year was promoted to lieutenant. Arnstadt functioned as a recruiter for the German Border Police until 1957 when he was appointed as a company commander of the 6th border company in Dermbach. Arnstadt was responsible for a section of the border at Wiesenfeld, a region of Bezirk Suhl in the Rhön Mountains at the westernmost point of the Warsaw Pact. Arnstadt's section contained the highly-strategic Fulda Gap, which aroused the special interest of NATO, and a short distance from the US Army's Observation Post Alpha. Arnstadt moved with his wife to Wiesenfeld and in April 1957 became an unofficial collaborator (Geheimer Informator) of the Ministry for State Security (Stasi) until this relationship was ended fourteen months later.
