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 cells are unable to remember specific pathogens? 
 disfluent question: Why are no what cells are unable to remember specific pathogens? 
 context: When B cells and T cells are activated and begin to replicate, some of their offspring become long-lived memory cells. Throughout the lifetime of an animal, these memory cells remember each specific pathogen encountered and can mount a strong response if the pathogen is detected again. This is adaptive because it occurs during the lifetime of an individual as an adaptation to infection with that pathogen and prepares the immune system for future challenges. Immunological memory can be in the form of either passive short-term memory or active long-term memory.

Output: No


Input: Consider Input: proper question: What percentage of the student body was affected by grade inflation in 2004? 
 disfluent question: What are the top no just percentage of the student body was affected by grade inflation in 2004? 
 context: Harvard's academic programs operate on a semester calendar beginning in early September and ending in mid-May. Undergraduates typically take four half-courses per term and must maintain a four-course rate average to be considered full-time. In many concentrations, students can elect to pursue a basic program or an honors-eligible program requiring a senior thesis and/or advanced course work. Students graduating in the top 4–5% of the class are awarded degrees summa cum laude, students in the next 15% of the class are awarded magna cum laude, and the next 30% of the class are awarded cum laude. Harvard has chapters of academic honor societies such as Phi Beta Kappa and various committees and departments also award several hundred named prizes annually. Harvard, along with other universities, has been accused of grade inflation, although there is evidence that the quality of the student body and its motivation have also increased. Harvard College reduced the number of students who receive Latin honors from 90% in 2004 to 60% in 2005. Moreover, the honors of John Harvard Scholar and Harvard College Scholar will now be given only to the top 5 percent and the next 5 percent of each class.

Output: No


Input: Consider Input: proper question: What appearance do dendritic cells and neuronal dendrites not share? 
 disfluent question: What serves erm what appearance do dendritic cells and neuronal dendrites not share? 
 context: Dendritic cells (DC) are phagocytes in tissues that are in contact with the external environment; therefore, they are located mainly in the skin, nose, lungs, stomach, and intestines. They are named for their resemblance to neuronal dendrites, as both have many spine-like projections, but dendritic cells are in no way connected to the nervous system. Dendritic cells serve as a link between the bodily tissues and the innate and adaptive immune systems, as they present antigens to T cells, one of the key cell types of the adaptive immune system.


Output: No
