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.

Example Input: Question: What is the population of the city where Chico Alencar received the most vote as a congressman of Socialism and Liberty Party? Passage:In 2010 Wyllys was elected a federal MP, representing the Socialism and Freedom party, with an average of 13,000 votes. His election was only possible, considering the number of votes he had in 2010 elections, through the so-called "voto de legenda" (party vote), a constitutional mechanism that allows candidates who don't have a large number of votes to be elected through votes of another highly voted candidate of the same party. In Wyllys's case, the votes of another congressman of Socialism and Liberty Party, Chico Alencar, who was one of the most voted in Rio de Janeiro, helped in his election. Upon occupying a seat in the Brazilian Congress, Wyllys brought his LGBT movement activism to the scene. He started working on his political platform, which was primarily focused on the fight for LGBT rights. In so doing, he ended up confronting prominent Brazilian right-wing figures, such as pastor Silas Malafaia, a famous televangelist and national president of the Assembly of God Churches, and Jair Bolsonaro, a congressman who became Wyllys's nemesis in the Brazilian Congress. Wyllys came to the point of spiting on congressman Bolsonaro during the voting of President Dilma Roussef's impeachment. In Congress, Wyllys proposed three controversial pieces of legislation, including the regulation of prostitution, the legalization and government regulation of marijuana production, and the government financing of sex reassignment surgeries and hormonal treatment for transgender teenagers and adults.

Example Input: Question: How many years did the Great Depression last? Passage:Originally from New Brunswick, Harrison graduated from Nova Scotia Agricultural College in 1922, and, in 1924, from the Ontario Agricultural College with a B.Sc. in agriculture. He earned an MSc in plant pathology from Macdonald Campus of McGill University a year later. A doctoral degree he started at the University of Toronto in 1929 was abandoned due to the Great Depression. He established a herbarium of mycological specimens where he was employed for many years at the Kentville Research Station (now the Atlantic Food and Horticulture Research Centre); most of his collections are now housed at the Canadian National Mycological Herbarium. His early research concerned the fungal infestation of plants, such as that of Colletotrichum lindemuthianum on beans (Phaseolus). Working with John Frederick DeWitt Hockey, they made many contributions to the control and prevention of diseases of horticultural crops. They were among the first to use the sticky slide spore trap to estimate the densities of fungal spores.

Example Input: Question: Who did Nikolay Novosiltsev work for? Passage:In 1817, while still a student, Mickiewicz, Tomasz Zan and other friends had created a secret organization, the Philomaths. The group focused on self-education but had ties to a more radical, clearly pro-Polish-independence student group, the Filaret Association. An investigation of secret student organizations by Nikolay Novosiltsev, begun in early 1823, led to the arrests of a number of students and ex-student activists including Mickiewicz, who was taken into custody and imprisoned at Vilnius' Basilian monastery in late 1823 or early 1824 (sources disagree as to the date). After investigation into his political activities, specifically his membership in the Philomaths, in 1824 Mickiewicz was banished to central Russia. Within a few hours of receiving the decree on 22 October 1824, he penned a poem into an album belonging to Salomea Becu, the mother of Juliusz Sowacki. (In 1975 this poem was set to music in Polish and Russian by Soviet composer David Tukhmanov.) Mickiewicz crossed the border into Russia about 11 November 1824, arriving in Saint Petersburg later that month. He would spend most of the next five years in Saint Petersburg and Moscow, except for a notable 1824 to 1825 excursion to Odessa, then on to Crimea. That visit, from February to November 1825, inspired a notable collection of sonnets (some love sonnets, and a series known as Crimean Sonnets, published a year later).
