Before revision:  Experimental results show that our proposed method (i) improves overall performance with more than 3\% accuracy points compared to previous state-of-the-art, and with over 18 \% points on a subset of problems that require more complex reasoning, and (ii) outperforms sequential LSTMs by 4\% accuracy points on such more complex problems.
