Before revision:  Experimental results showed that our model outperforms the state-of-the-art  pretrained language models on standard question answering benchmarks, and reaches the state-of-the-art performance under the zero-shot learning setting.
After revision:  Experimental results showed that our model outperforms the state-of-the-art pretrained language models and zero-shot approaches on standard question-answering benchmarks, and reaches the state-of-the-art performance under the zero-shot learning setting.
