input question: Extract the answer to the question from the following context. Question: What is the role of the bank? Context: In central banking, the privileged status of the central bank is that it can make as much money as it deems needed. In the United States Federal Reserve Bank, the Federal Reserve buys assets: typically, bonds issued by the Federal government. There is no limit on the bonds that it can buy and one of the tools at its disposal in a financial crisis is to take such extraordinary measures as the purchase of large amounts of assets such as commercial paper. The purpose of such operations is to ensure that adequate liquidity is available for functioning of the financial system.???

input question: Extract the answer to the question from the following context. Question: Scout's mother is? Context: Absent mothers and abusive fathers are another theme in the novel. Scout and Jem's mother died before Scout could remember her, Mayella's mother is dead, and Mrs. Radley is silent about Boo's confinement to the house. Apart from Atticus, the fathers described are abusers. Bob Ewell, it is hinted, molested his daughter, and Mr. Radley imprisons his son in his house until Boo is remembered only as a phantom. Bob Ewell and Mr. Radley represent a form of masculinity that Atticus does not, and the novel suggests that such men as well as the traditionally feminine hypocrites at the Missionary Society can lead society astray. Atticus stands apart as a unique model of masculinity; as one scholar explains: "It is the job of real men who embody the traditional masculine qualities of heroic individualism, bravery, and an unshrinking knowledge of and dedication to social justice and morality, to set the society straight."???

input question: Extract the answer to the question from the following context. Question: What can interfere how pain is perceived? Context: Although unpleasantness is an essential part of the IASP definition of pain, it is possible to induce a state described as intense pain devoid of unpleasantness in some patients, with morphine injection or psychosurgery. Such patients report that they have pain but are not bothered by it; they recognize the sensation of pain but suffer little, or not at all. Indifference to pain can also rarely be present from birth; these people have normal nerves on medical investigations, and find pain unpleasant, but do not avoid repetition of the pain stimulus.???

morphine injection or psychosurgery
