In this task, you will be presented with a context from an academic paper and a question based on the context. You have to classify the questions into "Extractive", "Abstractive", or "Yes-no" questions. Extractive questions can be answered by concatenating extracts taken from a context into a summary while answering abstractive questions involves paraphrasing the context using novel sentences. Yes-no question is a question whose expected answer is one of two choices, one that affirms the question and one that denies the question. Typically, the choices are either yes or no.

Example Input: On the same architecture, our RCRN outperforms ablative baselines BiLSTM by INLINEFORM2 and 3L-BiLSTM by INLINEFORM3 on average across 16 datasets. 
 Question: By how much do they outperform BiLSTMs in Sentiment Analysis?
Example Output: Abstractive

Example Input: The National Gang Threat Assessment Report confirms that at least tens of thousands of gang members are using social networking websites such as Twitter and video sharing websites such as YouTube in their daily life BIBREF0 . They are very active online; the 2007 National Assessment Center's survey of gang members found that 25% of individuals in gangs use the Internet for at least 4 hours a week BIBREF4 . 
 Question: Do the authors provide evidence that 'most' street gang members use Twitter to intimidate others?
Example Output: Yes-no

Example Input: In addition, in order to estimate annotation reliability and provide for better evaluation, every question in the test set is answered by at least two additional experts. 
 Question: Are the answers double (and not triple) annotated?
Example Output:
Yes-no
