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.

[Q]: Question: How many years passed between the First Carlist War and the  war that mostly in Catalonia? Passage:The Basque Country was one of the main sites of battles during the First Carlist War, a civil war between supporters of the Spanish regent Maria Christina, known as liberals, and those of the late king's brother Carlos of Borbón, known as Carlists. The Carlists were particularly focused on capturing Bilbao, a liberal and economic bastion in northern Spain. The Carlist general Tomás de Zumalacárregui tried to take the city during the Siege of Bilbao of 1835, but he was wounded during a battle near Begoña and died some time after in the town of Zegama. The next year, the city resisted a second siege during which the liberal general Baldomero Espartero defeated the Carlists in the Battle of Luchana. The city was untouched by the Second Carlist War, which took place mostly in Catalonia, but was again an important scenario during the Third Carlist War; in April 1874 the city suffered a third siege which lasted two months.

[Q]: Question: Why did the Nok culture die off about 200 AD on the Jos Plateau? Passage:The Nok culture thrived from approximately 1,500 BC to about 200 AD on the Jos Plateau in north and central Nigeria and produced life-sized terracotta figures that include human heads, human figures, and animals. Iron smelting furnaces at Taruga, a Nok site, date from around 600 BC. The Nok culture is thought to have begun smelting iron by 600-500 BC and possibly some centuries earlier. Kainji Dam excavations revealed iron-working by the 2nd century BC. Evidence of iron smelting has also been excavated at sites in the Nsukka region of southeast Nigeria in what is now Igboland: dating to 2,000 BC at the site of Lejja (Uzomaka 2009) and to 750 BC and at the site of Opi (Holl 2009). The transition from Neolithic times to the Iron Age apparently was achieved indigenously without intermediate bronze production. Others have suggested that the technology moved west from the Nile Valley, although the Iron Age in the Niger River valley and the forest region appears to predate the introduction of metallurgy in the upper savanna by more than 800 years. The earliest iron technology in West Africa has also been found to be contemporary with or predate that of the Nile valley and North Africa, and some archaeologists believe that iron metallurgy was likely developed independently in sub-Saharan West Africa.

[Q]: Question: Which road is longer, KY 1319 (Kings Church Road) or KY 155 (Taylorsville Lake Road)? Passage:Kentucky Route 1531 is a rural secondary highway that begins in northeastern Bullitt County and ends in northwestern Shelby County, but the route spends almost all of its length in the city of Louisville in eastern Jefferson County. The highway begins at KY 1319 (Kings Church Road) near Whitfield. KY 1531 heads northwest along Dawson Hill Road then turns northeast onto Routt Road to enter the city of Louisville and Jefferson County. The highway crosses Wheelers Run and Back Run and meets the eastern end of KY 1819 (Brush Run Road) south of the Routt neighborhood of Louisville. KY 1531 follows Sheckels Run to its crossing of Cane Run and reaches KY 155 (Taylorsville Lake Road) south of Fisherville. The highway runs concurrently with KY 155 northwest across Floyds Fork of the Salt River to KY 148 (Taylorsville Road), with which the route heads east through Fisherville and across Floyds Fork again.
