instruction:
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.
question:
proper question: What says that formations must be older than the inclusions inside them? 
 disfluent question: Who or no make that what says that formations must be older than the inclusions inside them? 
 context: The principle of inclusions and components states that, with sedimentary rocks, if inclusions (or clasts) are found in a formation, then the inclusions must be older than the formation that contains them. For example, in sedimentary rocks, it is common for gravel from an older formation to be ripped up and included in a newer layer. A similar situation with igneous rocks occurs when xenoliths are found. These foreign bodies are picked up as magma or lava flows, and are incorporated, later to cool in the matrix. As a result, xenoliths are older than the rock which contains them.
answer:
None


question:
proper question: What do bacteria use to move proteins from the host to the pathogen? 
 disfluent question: What do bacteria use to move proteins from the host to the barrier, sorry, pathogen? 
 context: The success of any pathogen depends on its ability to elude host immune responses. Therefore, pathogens evolved several methods that allow them to successfully infect a host, while evading detection or destruction by the immune system. Bacteria often overcome physical barriers by secreting enzymes that digest the barrier, for example, by using a type II secretion system. Alternatively, using a type III secretion system, they may insert a hollow tube into the host cell, providing a direct route for proteins to move from the pathogen to the host. These proteins are often used to shut down host defenses.
answer:
None


question:
proper question: What type of sanctions has Canada directed at Iran? 
 disfluent question: What type of republic dude I mean sanctions has Canada directed at Iran? 
 context: The Islamic Republic has also maintained its hold on power in Iran in spite of US economic sanctions, and has created or assisted like-minded Shia terrorist groups in Iraq, Egypt, Syria, Jordan (SCIRI) and Lebanon (Hezbollah) (two Muslim countries that also have large Shiite populations). During the 2006 Israel-Lebanon conflict, the Iranian government enjoyed something of a resurgence in popularity amongst the predominantly Sunni Arab street, due to its support for Hezbollah and to President Mahmoud Ahmadinejad's vehement opposition to the United States and his call that Israel shall vanish.
answer:

None
