In this task, you're given a question, a context passage, and four options which are terms from the passage. After reading a passage, you will get a brief understanding of the terms. Your job is to determine by searching and reading further information of which term you can answer the question. Indicate your choice as 'a', 'b', 'c', or 'd'. If you think more than one option is plausible, choose the more probable option to help you answer the question.

Question: How old was Waledynski when the autocephaly he requested was finally granted? Passage:The establishment of the church was undertaken after the Treaty of Riga left a large amount of territory previously under the control of the Russian Empire, as part of the Second Polish Republic. Eastern Orthodoxy was widespread in the Belarusian Western Belarus regions and the Ukrainian Volhynia. The loss of ecclesiastical link due to the persecution of the Russian Orthodox Church in the Soviet Union, left the regional clergy in a crisis moment, and in 1924, the Ecumenical Patriarchate took over establishing several autonomous churches on territories of the new states that were formerly wholly or partially part of the Russian Empire (Finland, the Baltic States, and Poland). Earlier, in January 1922, the Polish government had issued an order recognizing the Orthodox church and placing it under the authority of the state. At that time a Ukrainian, Yurii Yaroshevsky, was appointed Metropolitan and exarch by the patriarch of Moscow. When Yaroshevsky began to reject the authority of Moscow Patriarchate, he was assassinated by a Russian monk. Nonetheless, his successor, Dionizy Waledynski (Dionisii Valedinsky), continued to work for the autocephaly of the Polish Orthodox church, which was finally granted by the Ecumenical Patriarch of Constantinople in his Tomos of 13 November 1924. Given that most of the parishioners were Ukrainians and Belarusians living in the Eastern areas of the newly independent Polish Second Republic, the Patriarch of Constantinople had a canonical basis to grant the Tomos to the Polish church as a successor of the Kyiv Metropolia, the former territory of Kyivan Rus' which Constantinople continued to see as its canonical territory (despite having agreed to allow Moscow to be its caretaker it in 1686). The Russian Orthodox Church at the time did not recognise the Polish autocephaly, as it did not recognise the autocephaly of the Orthodox Church of the Czech Lands and Slovakia.

Question: What is the capital city of the country where Orson K. Miller claims to have found the Amanita abrupta? Passage:The fruit bodies of A.abrupta grow on the ground, typically solitary, in mixed conifer and deciduous forests, usually during autumn. The frequency with which fruit bodies appear depends on several factors, such as season, location, temperature, and rainfall. The mushroom has been described as common in the Southeastern United States; in Texas, it has been called both infrequent, and common in the Big Thicket National Preserve. Like most other Amanita species, A.abrupta is thought to form mycorrhizal relationships with trees. This is a mutually beneficial relationship where the hyphae of the fungus grow around the roots of trees, enabling the fungus to receive moisture, protection and nutritive byproducts of the tree, and affording the tree greater access to soil nutrients. Amanita abrupta is widely distributed throughout eastern North America, where it has been found as far north as Quebec, Canada, and as far south as Mexico. Orson K. Miller claims to have found it in the Dominican Republic where it appeared to be growing in a mycorrizhal association with pine trees. Kuo also mentions a mycorrhizal relationship with both hardwoods and conifers, while Tulloss lists additional preferred tree hosts such as beech, birch, fir, tsuga, oak, and poplar. However, A.abrupta has been shown experimentally to not form mycorrhizae with Virginia Pine.

Question: How many years after the Apollo 11 mission did the Apollo 17 mission launch? Passage: are three views of Mare Tranquillitatis on the Moon, taken by the mapping camera of the Apollo 17 mission in 1972, facing south-southwest from an average altitude of 111km on Revolution 36 of the mission. At the left is the east side of Mare Tranquillitatis, with the craters Franz (bottom right), Lyell (dark floor, right of center), and Taruntius (upper left). The "bay" of dark mare (basalt) at left is Sinus Concordiae, with "islands" of older, light highland material. At the right is the crater Cauchy, which lies between the Rupes Cauchy and Cauchy rille. The center photo shows the central mare with craters Vitruvius (lower right) and Gardner (bottom center). At the horizon are lighter highlands at the southern margin of the mare, near the Apollo 11 landing site. The crater Jansen is visible at the edges of both the center and right photos. The right photo shows the western mare, with the craters Dawes (lower left) and the large Plinius (43km diameter), with the Plinius Rilles in the foreground. These photos were taken within minutes of each other as the command module America orbited the Moon. The Sun elevation drops from 46 degrees at left to 30 degrees at right.
