In this task, you're given a question, along with a context passage which has extra information available on certain terms mentioned in it, i.e., the proper nouns in the passage. Your job is to determine whether information from more than one term is needed to answer the question. Indicate your choice as 'a' for Yes or 'b' for No.
Example: Question: When did the operation during which the 704th dropped supplies to allied troops near Nijmegen begin? Passage: The group was occasionally diverted from strategic missions to carry out air support and interdiction missions. It supported Operation Overlord, the invasion of Normandy by attacking transportation targets, including bridges, along with airfields and strong points in France. On D Day, the squadron and the rest of the 446th Group led the first heavy bomber mission of the day. The 446th aided ground forces at Caen and Saint-Lo during July by hitting bridges, gun batteries, and enemy troops. During Operation Market Garden, the attempt to seize a bridgehead across the Rhine in the Netherlands, the 704th dropped supplies to allied troops near Nijmegen. It struck lines of communications during the Battle of the Bulge. During Operation Varsity in March 1945, it supplied ground and airborne troops near Wesel. The squadron flew its last combat mission on 25 April 1945 against Salzburg, Austria. The group had flown 273 missions and had lost 58 aircraft during the war,
.
Example solution: b
Example explanation: The passage describes the 704th's actions during Operation Market Garden so only information about the operation is needed.

Problem: Question: Who was the ruler of the Russian Empire when the Polish Orthodox Church was established after the Treaty of Riga? 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.
Solution: a
