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.

Q: proper question: What are ancient processes used to do? 
 disfluent question: What are ancient stratigraphers um wait processes used to do? 
 context: In the laboratory, stratigraphers analyze samples of stratigraphic sections that can be returned from the field, such as those from drill cores. Stratigraphers also analyze data from geophysical surveys that show the locations of stratigraphic units in the subsurface. Geophysical data and well logs can be combined to produce a better view of the subsurface, and stratigraphers often use computer programs to do this in three dimensions. Stratigraphers can then use these data to reconstruct ancient processes occurring on the surface of the Earth, interpret past environments, and locate areas for water, coal, and hydrocarbon extraction.

Q: proper question: What type of outlook do some of the non-Muslims in London have? 
 disfluent question: How many er what type of outlook do some of the non-Muslims in London have? 
 context: Greater London has over 900,000 Muslims, (most of South Asian origins and concentrated in the East London boroughs of Newham, Tower Hamlets and Waltham Forest), and among them are some with a strong Islamist outlook. Their presence, combined with a perceived British policy of allowing them free rein, heightened by exposés such as the 2007 Channel 4 documentary programme Undercover Mosque, has given rise to the term Londonistan. Following the 9/11 attacks, however, Abu Hamza al-Masri, the imam of the Finsbury Park Mosque, was arrested and charged with incitement to terrorism which has caused many Islamists to leave the UK to avoid internment.[citation needed]

Q: proper question: Particle physics has created a Unique Model to describe what? 
 disfluent question: Particle physics has created a Unique Model to describe who or rather what? 
 context: With modern insights into quantum mechanics and technology that can accelerate particles close to the speed of light, particle physics has devised a Standard Model to describe forces between particles smaller than atoms. The Standard Model predicts that exchanged particles called gauge bosons are the fundamental means by which forces are emitted and absorbed. Only four main interactions are known: in order of decreasing strength, they are: strong, electromagnetic, weak, and gravitational.:2–10:79 High-energy particle physics observations made during the 1970s and 1980s confirmed that the weak and electromagnetic forces are expressions of a more fundamental electroweak interaction.
