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: How many Boy Wonder's have there been? Passage:Besides the aforementioned death of Stephanie Brown, many other side effects came about from this event. The biggest of these included Black Mask becoming the single crime boss in Gotham, something that would remain until his death at the hands of Catwoman. Another would be Commissioner Akins effectively making all vigilantes criminals, a move that would stay in place for over a year until the return of Commissioner Gordon to the Gotham City Police Department. The more controversial effect, not seen until the follow-up story War Crimes, was turning Doctor Leslie Thompkins against Batman, when she allows Stephanie Brown to die from her wounds as Batman's "punishment" for including children in his war on crime. Jason Todd, a former Boy Wonder, confirmed to be alive on  as a violent vigilante the Red Hood who waged a one-man war against Black Mask and successfully crippling his criminal operation in the city before seeking revenge towards Batman and the Joker. Finally, the citizens of Gotham City no longer consider Batman to be an urban legend (which has been in place since Zero Hour), as he was caught on camera trying to save the life of a wounded student at the end of Act One. Additionally, Barbara Gordon lost the clock tower that served as her home and headquarters and left Gotham City, eventually moving to Metropolis. She would later re-establish her ties to Batman.

Example Input: Question: Of the two provinces to the east of Montreal, which has the largest land area? Passage:As a British colony, and with immigration no longer limited to members of the Roman Catholic religion, the city began to grow from British immigration. American Revolutionists under General Richard Montgomery briefly captured the city during the 1775 invasion of Canada but left when it became obvious they could not hold Canada. Often having suffered loss of property and personal attacks during hostilities, thousands of English-speaking Loyalists migrated to Canada from the American colonies during and after the American Revolution. In 1782, John Molson estimated the population of the city at 6,000. The government provided most with land, settling them in what became Upper Canada (Ontario) to the west, as well as Nova Scotia and New Brunswick to the east. The first Protestant church in Montreal was St. Gabriel's, established by a Presbyterian missionary in 1792. With 19th-century immigration, more and more English-speaking merchants and residents continued to arrive in what had by then become known as Montreal. Soon the main language of commerce in the city was English. The golden era of fur trading began in the city with the advent of the locally owned North West Company, the main rival to the primarily British Hudson's Bay Company. The first machine shop in Montreal, owned by one George Platt, was in operation before 1809. The census of 1821 numbered 18,767 residents.
