have you ever thought about the way the different parts of our body communicate ? i think we often consider the body to be this one complete thing , this self . but really our body is composed of lots of parts . there are lots of organ systems . and each of those has organs . and all of those organs are made of tissues...	and so it makes adh and oxytocin . and adh is antidiuretic hormone . and it 's a main regulator of our fluid volume in our body .	isnt the posterior pituitary the one that releases oxytosin and adh ?

Dataset Summary

LearningQ, a challenging educational question generation dataset containing over 230K document-question pairs by [Guanliang Chen, Jie Yang, Claudia Hauff and Geert-Jan Houben]. It includes 7K instructor-designed questions assessing knowledge concepts being taught and 223K learner-generated questions seeking in-depth understanding of the taught concepts. This new version collected and corrected from over than 50000 error and more than 1500 type of error by Sidali Lamri
