Task: Question Answering
Input (English): Most of the above-discussed systems either shows high performance on (a) Twitter dataset or (b) Facebook dataset (given in the TRAC-2018), but not on both English code-mixed datasets. This may be due to the text style or level of complexities of both datasets. 
 Question: How have the differences in communication styles between Twitter and Facebook increase the complexity of the problem?
Output (English): Systems do not perform well both in Facebook and Twitter texts
