instruction:
In this task, you're given a question, a context passage, and four options which are terms from the passage. After reading a passage, you will get a brief understanding of the terms. Your job is to determine by searching and reading further information of which term you can answer the question. Indicate your choice as 'a', 'b', 'c', or 'd'. If you think more than one option is plausible, choose the more probable option to help you answer the question.
question:
Question: Was Montana the quarterback during each of Walsh's Super Bowl wins? Passage:Walsh first developed what would become the West Coast offense when he was offensive coordinator of the Cincinnati Bengals, working under legendary head coach Paul Brown. However, Walsh truly perfected this strategy as the head coach of the San Francisco 49ers. His teams were led by quarterback Joe Montana. Montana, who was noted for his ability to remain calm under pressure, also possessed good mobility and an accurate passing arm. Another important player in the 49ers offense was Roger Craig, a swift, speedy running back who could also catch passes out of the backfield and was a good receiver. Walsh's 49ers teams also featured several All-Pro wide receivers, including Dwight Clark, John Taylor, and Jerry Rice. The 49ers were one of the NFL's powerhouses in the 1980s and 1990s, under the guidance of head coaches Bill Walsh (1979–1988) and George Seifert (1989–1996). Walsh won three Super Bowls in the 1981, 1984 and 1988 seasons. Seifert won two Super Bowls in 1989 and 1994. Montana, Walsh and Rice are in the Pro Football Hall of Fame, and so is Montana's successor, quarterback Steve Young. Like Montana, Young was a great running quarterback and a very efficient passer.

question:
Question: What countries was John Hope's Brigade stationed in? Passage:Hope joined the Scots Brigade as a cadet in 1778. The Brigade, in the service of the Dutch Republic, was then stationed at Bergen op Zoom and later moved to Maastricht. He had reached the rank of Captain when like other officers he left the Dutch service in 1782 during the Fourth Anglo-Dutch War and was on half-pay until 29 September 1787, when he joined the 60th Foot (Royal American Regiment), but the regiment was reduced and he was briefly on half-pay again before joining the 13th Light Dragoons on 30 June 1788. In February 1793, shortly after the French Revolutionary War had begun, Hope served as aide-de-camp to Sir William Erskine in the Flanders Campaign. On 25 March 1795, a few days after Erskine's death, Hope was promoted to major in the 28th Light Dragoons, becoming lieutenant-colonel of that regiment on 20 February 1796. Sent to the Cape Colony, the 28th, under Hope's command, helped to rebuff a Dutch attempt in August, to reclaim the colony.

question:
Question: Which mountain range is higher, the Precordillera or the Andes? Passage:The Precordillera terrane of western Argentina is a large mountain range located southeast of the main Andes mountain range. The evolution of the Precordillera is noted for its unique formation history compared to the region nearby. The Cambrian-Ordovian sedimentology in the Precordillera terrane has its source neither from old Andes nor nearby country rock, but shares similar characteristics with the Grenville orogeny of eastern North America. This indicates a rift-drift history of the Precordillera in the early Paleozoic. The Precordillera is a moving micro-continent which started from the southeast part of the ancient continent Laurentia (current location: North American plate). The separation of the Precordillera (also named Cuyania) started around the early Cambrian. The mass collided with Gondwana (the ancient supercontinent in the southern hemisphere) around Late Ordovician period. Different models and thinking of rift-drift process and the time of occurrence have been proposed. This page focuses on the evidence of drifting found in the stratigraphical record of the Precordillera, as well as exhibiting models of how the Precordillera drifted to Gondwana.
