The key difference between RACE and previously released machine comprehension datasets (e.g., the CNN/Daily Mail dataset (Hermann et al., 2015) and SQuAD (Rajpurkar et al., 2016)) is that the answers in RACE often cannot be directly extracted from the given passages, as illustrated by the two example questions (Q1 & Q2) in Figure 1.
answering these questions is more challenging and requires more inferences.
