TASK DEFINITION: In this task you are given a disfluent question, a proper question and a context. A disfluent question is a question that has some interruptions in it while framing and a proper question is the correct form of the question without any disfluency. Classify whether the question is answerable or not based on the given context.
PROBLEM: proper question: What type of group is The Islamic State?
disfluent question: What is the Islamic State no no what kind of people make up the Islamic State?
context: The Islamic State, formerly known as the Islamic State of Iraq and the Levant and before that as the Islamic State of Iraq, (and called the acronym Daesh by its many detractors), is a Wahhabi/Salafi jihadist extremist militant group which is led by and mainly composed of Sunni Arabs from Iraq and Syria. In 2014, the group proclaimed itself a caliphate, with religious, political and military authority over all Muslims worldwide. As of March 2015[update], it had control over territory occupied by ten million people in Iraq and Syria, and has nominal control over small areas of Libya, Nigeria and Afghanistan. (While a self-described state, it lacks international recognition.) The group also operates or has affiliates in other parts of the world, including North Africa and South Asia.

SOLUTION: Yes

PROBLEM: proper question: Where weren't populations centered in colonies?
disfluent question: How nope I mean where weren't populations centered in colonies?
context: British settlers outnumbered the French 20 to 1 with a population of about 1.5 million ranged along the eastern coast of the continent, from Nova Scotia and Newfoundland in the north, to Georgia in the south. Many of the older colonies had land claims that extended arbitrarily far to the west, as the extent of the continent was unknown at the time their provincial charters were granted. While their population centers were along the coast, the settlements were growing into the interior. Nova Scotia, which had been captured from France in 1713, still had a significant French-speaking population. Britain also claimed Rupert's Land, where the Hudson's Bay Company traded for furs with local tribes.

SOLUTION: No

PROBLEM: proper question: What do NK cells protect?
disfluent question: What part no What do NK cells protect?
context: Natural killer cells, or NK cells, are a component of the innate immune system which does not directly attack invading microbes. Rather, NK cells destroy compromised host cells, such as tumor cells or virus-infected cells, recognizing such cells by a condition known as missing self. This term describes cells with low levels of a cell-surface marker called MHC I (major histocompatibility complex) a situation that can arise in viral infections of host cells. They were named natural killer because of the initial notion that they do not require activation in order to kill cells that are missing self. For many years it was unclear how NK cells recognize tumor cells and infected cells. It is now known that the MHC makeup on the surface of those cells is altered and the NK cells become activated through recognition of missing self. Normal body cells are not recognized and attacked by NK cells because they express intact self MHC antigens. Those MHC antigens are recognized by killer cell immunoglobulin receptors (KIR) which essentially put the brakes on NK cells.

SOLUTION:
No
