Besides the single BiDAF, the single Match LSTM, the ensemble Match LSTM, and the ensemble BiDAF achieve an F1 of 7.6, 11.7, and 2.7 respectively in question answering on ADDANY adversarial dataset<cite> (Jia and Liang, 2017)</cite> . Therefore, question answering with adversarial sentences in paragraphs is a prominent issue and is the focus of this study.
