TASK DEFINITION: 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.
PROBLEM: In all our experiments, we used the out-of-the-box BERT models without any task-specific fine-tuning. 
 Question: How does their model differ from BERT?

SOLUTION: Abstractive

PROBLEM: In ConvE, only $v_h$ and $v_r$ are reshaped and then concatenated into an input matrix which is fed to the convolution layer 
 Question: Did the authors try stacking multiple convolutional layers?

SOLUTION: Yes-no

PROBLEM: To test this hypothesis we first trained UG-WGAN in English, Chinese and German following the procedure described in Section "UG-WGAN" . For this experiment we trained UG-WGAN on the English and Russian language following the procedure described in Section "UG-WGAN" .  To do so we trained 6 UG-WGAN models on the following languages: English, Russian, Arabic, Chinese, German, Spanish, French. 
 Question: What are the languages they consider in this paper?

SOLUTION:
Abstractive
