Given the task definition and input, reply with output. In this task, you're given a question, along with three passages, 1, 2, and 3. Your job is to determine which passage can be used to answer the question by searching for further information using terms from the passage. Indicate your choice as 1, 2, or 3.

Question: Where are the neurotransmitters that block the transmissions between neurons created? Passage 1:The Dangerous Liaisons is an opera in two acts and eight scenes, with music by Conrad Susa to an English libretto by Philip Littell. It is based on the novel Les Liaisons dangereuses by Pierre Choderlos de Laclos. The opera has set numbers with recitative and spoken dialog. It is set in France in the 18th century. The opera received its first performance by the San Francisco Opera on 10 September 1994, with stage direction by Colin Graham and Donald Runnicles as the conductor. The world-premiere cast included Thomas Hampson as Valmont, Frederica von Stade as Merteuil, David Hobson as Chevalier de Danceny, Renee Fleming as Tourvel and Mary Mills as Cecile de Volanges. The opera was performed at Washington Opera in March 1998. It was also aired on the American PBS television network's Great Performances, a video recording of which was also made. Albany Records released an audio recording of a performance by Manhattan School of Music Opera Theater in 2016.
Passage 2:Behavioral neuroscience applies the principles of neurobiology, to the study of physiological, genetic, and developmental mechanisms of behavior. Cognitive inhibition is caused by several different interacting biological factors. The first is the existence of inhibitory neurotransmitters, or chemicals emitted by brain cells to both communicate and inhibit communication between each other. "GABA, an inhibitory transmitter substance that has been implicated in certain simple behavioral measures of inhibition and the control of aggressive behavior, was discovered in the cerebral cortex in substantial quantities". Given the cerebral cortex's importance in many brain functions such as memory and thought, the presence of the inhibitory substance GABA supports the cognitive inhibition processes that go on in this area of the brain. Serotonin and dopamine, which can play inhibitory roles as well, are present in the brain in large quantities. All three of these neurotransmitters are capable of "blocking" the transmissions between neurons, which can ultimately result in cognitive inhibition. In addition, the presence of inhibitory connections in the central nervous system has been firmly demonstrated (Eccles, 1969). A process known as lateral inhibition, which involves the capacity of an excited neuron to reduce the activity of its neighbors, is integral in the biology of cognitive inhibition. It provides much of the neural background behind it and explains what exactly is going on at the cellular level.
Passage 3:Jasanoff's 2017 book, The Dawn Watch: Joseph Conrad in a Global World, published by Penguin Press and in the UK by William Collins centers on the life and times of novelist Joseph Conrad. The Times lauded the book as the "Conrad for our time," and The Spectator called her an "enviably gifted writer...her historian's eye can untie knots that might baffle the pure critic," noting that she "steers us securely and stylishly through those latitudes where Conrad witnessed the future scupper the past." In the judgment of the Financial Times: "This is an unobtrusively skilful, subtle, clear-eyed book, beautifully narrated," while the Literary Review observes: "Written with a novelist's flair for vivid detail and a scholar's attention to texts, The Dawn Watch is by any standard a major contribution to our understanding of Conrad and his time." Reviewing the book in The Guardian, Patrick French began: "The Dawn Watch will win prizes, and if it doesn't, there is something wrong with the prizes." In The Hindu, Sudipta Datta wrote that Jasanoff's approach to Conrad makes for a "remarkable retelling of Joseph Conrad's life and work and its resonance with the present dysfunctional world." In The Guardian, William Dalrymple named the book to his list of best holiday reads of 2017. According to the Wall Street Journal's reviewer, "'The Dawn Watch' is the most vivid and suggestive biography of Conrad ever written." In The New York Times, Ngugi wa Thiong'O applauded the book as "masterful." Thiong'O wrote that Jasanoff succeeded where "An Image of Africa: Racism in Joseph Conrad's Heart of Darkness," Chinua Achebe's classic Conrad essay, had failed, specifically in bringing into clear relief "Conrad's ability to capture the hypocrisy of the 'civilizing mission' and the material interests that drove capitalist empires, crushing the human spirit." "'The Dawn Watch,' Thiong'O wrote, "will become a creative companion to all students of his work. It has made me want to re-establish connections with the Conrad whose written sentences once inspired in me the same joy as a musical phrase."
