Task: Question Answering
Input (English): Context: So I took 9 tests and 3 placed me as a Gryph , 3 placed me in Ravenclaw , and 3 clearly marked me as a Hufflepuff . Hmmmmm ... Whiled I 'd like to be one of the first two , I secretly think I ' m a Hufflepuff . You all know me well . Do you think I ' m right?What gets interesting is I did a wand selector test- 3 times . Each time the results were the same . 
Question: What may be the reason they took the same test 9 times ?
Output (English): Because they wanted to make sure they got accurate results .
