Task: Question Generation
Input (English): Our user study compares the correctness of three scenarios:

Parser correctness - our baseline is the percentage of examples where the top query returned by the semantic parser was correct.

User correctness - the percentage of examples where the user selected a correct query from the top-7 generated by the parser.

Hybrid correctness - correctness of queries returned by a combination of the previous two scenarios. The system returns the query marked by the user as correct; if the user marks all queries as incorrect it will return the parser's top candidate.
Output (English): Do they conduct a user study where they show an NL interface with and without their explanation?
