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 years after Wish You Were Here was released was The Wall released? Passage:Storm Thorgerson, who had done the majority of album covers for Pink Floyd, did the Echoes art which features recursive windows in an infinite regression as a nod to his own cover for 1969's Ummagumma, and the objects on each landscape refer to the Pink Floyd discography. For instance, there's the man on fire from Wish You Were Here, another wearing the Delicate Sound of Thunder lightbulb suit, dolls of the Atom Heart Mother cow and the Animals pig, a bike and both a brick wall and the hammers from The Wall. Eventually Thorgerson opted to make two images, with another used for the back cover. To create the idea on a photograph, various walls - which had varied measurements and angles to ensure that "nothing seemed to fit other than by eye through the lens." - were built and put in a country landscape in Sussex. Actors, props and fittings were set in and between those walls. The original design was one of two sketches submitted for Dream Theater's 1997 album Falling into Infinity, with the original being framed and hanging in the home of former Dream Theater drummer Mike Portnoy and is pointed out by Portnoy in his Hudson Music instructional drum DVD In Constant Motion.

Example Input: Question: Did any Giants players play in the 1984 All-Star game? Passage:The 2007 Major League Baseball All-Star Game was the 78th midseason exhibition between the all-stars of the American League (AL) and the National League (NL), the two leagues comprising Major League Baseball. The game was held on July 10, 2007, at AT&T Park, the home of the NL's San Francisco Giants. It marked the third time that the Giants hosted the All Star Game since moving to San Francisco for the 1958 season. The 1961 and 1984 All Star Games were played at the Giants former home Candlestick Park, and the fourth overall in the Bay Area, with the Giants bay area rivals the Oakland Athletics hosting once back in 1987, and the second straight held in an NL ballpark.

Example Input: Question: Who headed the government that the Ligurian Republic was modeled on? Passage:The value of trade routes through Genoa to the Near East declined during the Age of Discovery, when Portuguese explorers discovered routes to Asia around the Cape of Good Hope. The international crises of the seventeenth century, which ended for Genoa with the 1684 bombardment by Louis XIV’s fleet, restored French influence over the republic. Consequently, the Ligurian territory was crossed by the Piedmontese and Austrian armies when these two states came into conflict with France. Austria occupied Genoa in 1746, but the Habsburg troops were driven away by a popular insurrection. Napoleon's first Italian campaign marked the end of the oligarchic Genoese state, which was transformed into the Ligurian Republic, modelled on the French Republic. After the union of Oneglia and Loano (1801), Liguria was annexed to the French Empire (1805) and divided by Napoleon into three departments: Montenotte (department), with capital Savona, Gênes, with capital Genoa and the department of the Apennines, with the capital Chiavari.
