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.

[EX Q]: A key benefit is that the RNN infers a latent representation of state, obviating the need for state labels. 
 Question: Does the latent dialogue state heklp their model?
[EX A]: Yes-no

[EX Q]: Three baseline classification methods: Support Vector Machines (SVM), Adaboost, and Random Forests are adopted to evaluate our extracted features. On each dataset, the employed classifiers are trained with individual feature first, and then with the combination of the two features. 
 Question: LDA is an unsupervised method; is this paper introducing an unsupervised approach to spam detection?
[EX A]: Yes-no

[EX Q]: In natural language, subjectivity refers to the aspects of communication used to express opinions, evaluations, and speculationsBIBREF0, often influenced by one's emotional state and viewpoints. In this work, we investigate the application of BERT-based models for the task of subjective language detection. Experiments ::: Dataset and Experimental Settings
We perform our experiments on the WNC dataset open-sourced by the authors of BIBREF2. It consists of aligned pre and post neutralized sentences made by Wikipedia editors under the neutral point of view. It contains $180k$ biased sentences, and their neutral counterparts crawled from $423,823$ Wikipedia revisions between 2004 and 2019 
 Question: Which experiments are perfomed?
[EX A]:
Abstractive
