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.

[EX Q]: Question: How old was Nusslein-Volhard when she won the Nobel Prize in Physiology and Medicine? Passage:The concept of the morphogen has a long history in developmental biology, dating back to the work of the pioneering Drosophila (fruit fly) geneticist, Thomas Hunt Morgan, in the early 20th century. Lewis Wolpert refined the morphogen concept in the 1960s with the French flag model, which described how a morphogen could subdivide a tissue into domains of different target gene expression (corresponding to the colours of the French flag). This model was championed by the leading Drosophila biologist, Peter Lawrence. Christiane Nusslein-Volhard was the first to identify a morphogen, Bicoid, one of the transcription factors present in a gradient in the Drosophila syncitial embryo. She was awarded the 1995 Nobel Prize in Physiology and Medicine for her work explaining the morphogenic embryology of the common fruit fly. Groups led by Gary Struhl and Stephen Cohen then demonstrated that a secreted signalling protein, Decapentaplegic (the Drosophila homologue of transforming growth factor beta), acted as a morphogen during the later stages of Drosophila development.

[EX Q]: Question: How many tracks did the album released in 2004 have? Passage:Fulber rejoined the band in 2003. The reunited duo released the single "Maniacal" in October of that year. The single peaked at No. 15 on Billboards Hot Dance Singles. The next year, they released the studio album Civilization, which landed the No. 2 position on the German Alternative Albums chart. Peterson later rejoined the band to release Artificial Soldier in 2006. It was the first album to feature new members Jeremy Inkel and Jared Slingerland. The album peaked on Billboards Top Dance/Electronic Albums chart at No. 19. After a problem with the tour bus company, the US tour that year was cut short, and the band returned home to Vancouver after playing roughly half of their scheduled dates; performances in New York and Canada were cancelled. The band toured in Europe in August 2006, playing in 18 cities.

[EX Q]: Question: In what country did the division Edmund commanded until May 1945 see most of its fighting in? Passage:During the Second World War Hakewill-Smith initially served as Commanding Officer (CO) of the 5th Battalion, Devonshire Regiment, for several months from May 1940 and from September that year, as the CO of the 4th/5th Battalion, Royal Scots Fusiliers, as an acting lieutenant colonel. He was promoted to temporary brigadier on 30 March 1941, and commanded the 157th Infantry Brigade until late March 1942. He then became Director of Organization at the War Office before assuming command of the 155th Infantry Brigade in mid-February 1943. On 26 December 1943, promoted to temporary major general, he assumed command of the mountain warfare-trained 52nd (Lowland) Infantry Division from Major-General Neil Ritchie as its General Officer Commanding (GOC). He commanded the 52nd Division during the campaign in North-West Europe, from October 1944 until May 1945.
