The dataset contains question-answer pairs to model verbal predicate-argument structure. 
The questions start with wh-words (Who, What, Where, What, etc.) and contain a verb predicate in the sentence; the answers are phrases in the sentence.
This dataset loads the train split from "QASRL Bank", a.k.a "QASRL-v2" or "QASRL-LS" (Large Scale), 
which was constructed via crowdsourcing and presented at (FitzGeralds et. al., ACL 2018), 
and the dev and test splits from QASRL-GS (Gold Standard), introduced in (Roit et. al., ACL 2020).
