In this task, you are given a question and a context passage. You have to answer the question based on the given passage.

Example Input: What is a concern when using the computer?, Context: Seemingly, multitasking would cause a computer that is switching between several programs to run more slowly, in direct proportion to the number of programs it is running, but most programs spend much of their time waiting for slow input/output devices to complete their tasks. If a program is waiting for the user to click on the mouse or press a key on the keyboard, then it will not take a "time slice" until the event it is waiting for has occurred. This frees up time for other programs to execute so that many programs may be run simultaneously without unacceptable speed loss.
Example Output: multitasking would cause a computer that is switching between several programs to run more slowly

Example Input: How is a husband referred to?, Context: Knights Grand Cross and Knights Commander prefix Sir, and Dames Grand Cross and Dames Commander prefix Dame, to their forenames.[b] Wives of Knights may prefix Lady to their surnames, but no equivalent privilege exists for husbands of Knights or spouses of Dames. Such forms are not used by peers and princes, except when the names of the former are written out in their fullest forms. Clergy of the Church of England or the Church of Scotland do not use the title Sir or Dame as they do not receive the accolade (i.e., they are not dubbed "knight" with a sword), although they do append the post-nominal letters.
Example Output: no equivalent privilege exists for husbands

Example Input: What was a model for global regulation?, Context: The IPCC process on climate change and its efficiency and success has been compared with dealings with other environmental challenges (compare Ozone depletion and global warming). In case of the Ozone depletion global regulation based on the Montreal Protocol has been successful, in case of Climate Change, the Kyoto Protocol failed. The Ozone case was used to assess the efficiency of the IPCC process. The lockstep situation of the IPCC is having built a broad science consensus while states and governments still follow different, if not opposing goals. The underlying linear model of policy-making of more knowledge we have, the better the political response will be is being doubted.
Example Output:
Montreal Protocol
