-_DESCRIPTION = """\
-The MRQA 2019 Shared Task focuses on generalization in question answering.
-An effective question answering system should do more than merely
-interpolate from the training set to answer test examples drawn
-from the same distribution: it should also be able to extrapolate
-to out-of-distribution examples — a significantly harder challenge.
-
-The dataset is a collection of 18 existing QA dataset (carefully selected
-subset of them) and converted to the same format (SQuAD format). Among
-these 18 datasets, six datasets were made available for training,
-six datasets were made available for development, and the final six
-for testing. The dataset is released as part of the MRQA 2019 Shared Task.
