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 Waledyński 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 Waledyński (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: How many species of the Aru Flying fox are there? Passage:Of the 62 flying fox species evaluated by the IUCN as of 2018, 3 are considered critically endangered: the Aru flying fox, Livingstone's fruit bat, and the Vanikoro flying fox. Another 7 species are listed as endangered; 20 are listed as vulnerable, 6 as near threatened, 14 as least concern, and 8 as data deficient. A further 4 are listed as extinct: the dusky flying fox, the large Palau flying fox, the small Mauritian flying fox, and the Guam flying fox. Over half of the species are threatened today with extinction, and in particular in the Pacific, a number of species have died out as a result of hunting, deforestation, and predation by invasive species. Six flying fox species are believed to have gone extinct from 1864 to 2014: the Guam, large Palau, small Mauritian, dusky, large Samoan, and the small Samoan flying foxes.

Question: How old was Steve Simonsen when Achterberg arrived as his replacement? Passage:Achterberg first signed for Tranmere Rovers in 1998, after a successful trial as a replacement for the Everton bound Steve Simonsen. He was immediately selected for the first team due to an injury to Danny Coyne, making his debut against Swindon Town on 25 September 1998. Achterberg then secured his place as Rovers' first choice goalkeeper after Coyne was transferred to Grimsby Town in 1999. Achterberg became part of the giant-killing cup teams that defeated such opponents as Everton, Southampton and other big teams. However after refusing to sign a new contract he was dropped by John Aldridge for the 2000 Football League Cup Final and replaced by Joe Murphy. Achterberg's proficiency in goal was exemplified by the 20 clean sheets he kept during the 2003–04 season under the stewardship of Brian Little. One of his more memorable performances was against Millwall in an FA Cup quarter final at The New Den which was televised on BBC 1. The game finished goalless, but was largely dominated by Millwall and John managed to save a penalty kick from Kevin Muscat, despite having to play through injury.
