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.

Input: Consider Input: proper question: What co-receptor recruits molecules inside the T cell that are responsible for cell activation? 
 disfluent question: What antigens do Helper T cells not recognize no sorry what co-receptor recruits molecules inside the T cell that are responsible for cell activation? 
 context: Helper T cells express T cell receptors (TCR) that recognize antigen bound to Class II MHC molecules. The MHC:antigen complex is also recognized by the helper cell's CD4 co-receptor, which recruits molecules inside the T cell (e.g., Lck) that are responsible for the T cell's activation. Helper T cells have a weaker association with the MHC:antigen complex than observed for killer T cells, meaning many receptors (around 200–300) on the helper T cell must be bound by an MHC:antigen in order to activate the helper cell, while killer T cells can be activated by engagement of a single MHC:antigen molecule. Helper T cell activation also requires longer duration of engagement with an antigen-presenting cell. The activation of a resting helper T cell causes it to release cytokines that influence the activity of many cell types. Cytokine signals produced by helper T cells enhance the microbicidal function of macrophages and the activity of killer T cells. In addition, helper T cell activation causes an upregulation of molecules expressed on the T cell's surface, such as CD40 ligand (also called CD154), which provide extra stimulatory signals typically required to activate antibody-producing B cells.

Output: Yes


Input: Consider Input: proper question: What isn't Raghuram Rajan's career? 
 disfluent question: What isn't Raghuram Rajan's credit urgh career? 
 context: Central Banking economist Raghuram Rajan argues that systematic economic inequalities, within the United States and around the world, have created deep financial 'fault lines' that have made [financial] crises more likely to happen than in the past – the Financial crisis of 2007–08 being the most recent example. To compensate for stagnating and declining purchasing power, political pressure has developed to extend easier credit to the lower and middle income earners – particularly to buy homes – and easier credit in general to keep unemployment rates low. This has given the American economy a tendency to go from bubble to bubble fueled by unsustainable monetary stimulation.

Output: No


Input: Consider Input: proper question: What region of China is Hebei part of? 
 disfluent question: What region of China is Inner Mongolia no is Hebei part of? 
 context: The Central Region, consisting of present-day Hebei, Shandong, Shanxi, the south-eastern part of present-day Inner Mongolia and the Henan areas to the north of the Yellow River, was considered the most important region of the dynasty and directly governed by the Central Secretariat (or Zhongshu Sheng) at Khanbaliq (modern Beijing); similarly, another top-level administrative department called the Bureau of Buddhist and Tibetan Affairs (or Xuanzheng Yuan) held administrative rule over the whole of modern-day Tibet and a part of Sichuan, Qinghai and Kashmir.


Output: Yes
