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: Where did the Occupy movement begin? Passage:Occupy Melbourne was a social movement which took place from late 2011 to mid 2012 in Melbourne, Australia as part of the global Occupy movement. Participants expressed grievances concerning economic inequality, social injustice, corruption in the financial sector, corporate greed and the influence of companies and lobbyists on government. Protests began on 15 October 2011 in City Square with a 6-day-long protest encampment, from which people were forcibly evicted by Victoria Police at the request of the City of Melbourne CEO on 21 October 2011. From 2 November 2011, Occupy set up camp in Treasury Gardens before being moved on from that location in December. A significantly diminished number of protesters set up camp at Father Bob's church at his invitation until his retirement in January 2012. Physical manifestations of the movement had largely dissipated by mid-2012 though it adopted a strategy of decentralisation and became influential in the creation of new community networks, affinity groups and collectives.

[EX Q]: Question: How much does the person Iron Man showed up at Grand Central Station with weigh? Passage:Doom hires various villains to find the bricks for him, starting with Abomination and Sandman, who hold Grand Central Station at ransom for a Cosmic Brick. Iron Man and Hulk show up at the station, with Spider-Man joining them later on, and together they manage to defeat the two villains, who are subsequently imprisoned in a nearby maximum security prison called the Raft, while Nick Fury leaves the Cosmic Brick in Mister Fantastic's care at the Baxter Building. Mister Fantastic and Captain America arrive at the building shortly after to examine the Cosmic Brick, but find it under attack by Doctor Octopus, who steals the brick and leaves his Octobots behind to keep the heroes busy. After destroying them, Mister Fantastic and Captain America chase after a fleeing Doctor Octopus across several rooftops, with their battle going through the Daily Bugle as well, where Peter Parker, Spider-Man's alter-ego, sees them and suits up as Spider-Man to lend a hand. The three heroes eventually battle Doctor Octopus in Times Square and manage to defeat him, but he tosses the brick to Green Goblin, who takes it to Oscorp. Fury sends Black Widow and Hawkeye to get it back, with Spider-Man joining them later on. They eventually confront Green Goblin in his office, but he opens a trapdoor that sends the heroes to Oscorp's underground lab, where they are forced to fight Venom and his symbiote-infected scientists. Although the heroes defeat Venom, the Goblin escapes with the brick via helicopter.
