_DESCRIPTION = """\
This is the Question Generation dataset released as part of IndicNLG Suite. Each 
example has five fields: id, squad_id, answer, context and question. We create this dataset in eleven 
languages including as, bn, gu, hi, kn, ml, mr, or, pa, ta, te. This is a translated data. The examples in each language are exactly similar but in different languages. 
The number of examples in each language is 98,027.
