Before revision:  Our experiments show that our proposed method outperforms baseline modelsin terms of accuracy of 61.81 \%, higher 5.51\% than the best baseline model. Besides, we measure human performance on our dataset and compared it to our MRC models. The performance gap between humans and our best experimental model indicates that significant progress can be made on Vietnamese machine reading comprehension in further research. Our dataset is freely available for research purposes.
