Use a disfluent question or a proper question and find the answer to the question based on the given context or return None if an answer can't be found. A disfluent question is a question that has some interruptions in it while framing. A proper question is the correct form of the question without any disfluency.

Input: Consider Input: proper question: What UN resolution endorsed the IPCC? 
 disfluent question: What UNFCCC resolution endorsed the IPCC no the UN not UNFCCC? 
 context: The Intergovernmental Panel on Climate Change (IPCC) is a scientific intergovernmental body under the auspices of the United Nations, set up at the request of member governments. It was first established in 1988 by two United Nations organizations, the World Meteorological Organization (WMO) and the United Nations Environment Programme (UNEP), and later endorsed by the United Nations General Assembly through Resolution 43/53. Membership of the IPCC is open to all members of the WMO and UNEP. The IPCC produces reports that support the United Nations Framework Convention on Climate Change (UNFCCC), which is the main international treaty on climate change. The ultimate objective of the UNFCCC is to stabilize greenhouse gas concentrations in the atmosphere at a level that would prevent dangerous anthropogenic [i.e., human-induced] interference with the climate system. IPCC reports cover the scientific, technical and socio-economic information relevant to understanding the scientific basis of risk of human-induced climate change, its potential impacts and options for adaptation and mitigation.

Output: Resolution 43/53


Input: Consider Input: proper question: The U of C has ties to several dependent institutions, including? 
 disfluent question: The U of C has ties to several dependent schools or no make that institutions, including? 
 context: The academic bodies of the University of Chicago consist of the College, four divisions of graduate research and seven professional schools. The university also contains a library system, the University of Chicago Press, the University of Chicago Laboratory Schools, and the University of Chicago Medical Center, and holds ties with a number of independent academic institutions, including Fermilab, Argonne National Laboratory, and the Marine Biological Laboratory. The university is accredited by The Higher Learning Commission.

Input: Consider Input: proper question: Between which years did the Mediterranean Sea flow into the Tethys sea? 
 disfluent question: Between which years did the Triassic Period flow into the Tethys sea no the Mediterranean Sea? 
 context: In southern Europe, the stage was set in the Triassic Period of the Mesozoic Era, with the opening of the Tethys Ocean, between the Eurasian and African tectonic plates, between about 240 MBP and 220 MBP (million years before present). The present Mediterranean Sea descends from this somewhat larger Tethys sea. At about 180 MBP, in the Jurassic Period, the two plates reversed direction and began to compress the Tethys floor, causing it to be subducted under Eurasia and pushing up the edge of the latter plate in the Alpine Orogeny of the Oligocene and Miocene Periods. Several microplates were caught in the squeeze and rotated or were pushed laterally, generating the individual features of Mediterranean geography: Iberia pushed up the Pyrenees; Italy, the Alps, and Anatolia, moving west, the mountains of Greece and the islands. The compression and orogeny continue today, as shown by the ongoing raising of the mountains a small amount each year and the active volcanoes.
