Task: Question Answering
Input (English): Context: After vigorous stirring , ( thanks to chemistry labs ) I shot a look towards my sister and asked , " Want to taste ? " A very smart girl that she is , said , " No , you give me the final product ! " I tasted and found that it was way too watery . I went on to add sugar and salt , by trial and error . It was okayish , after some efforts . 
Question: What may be the reason why the sister did n't want to taste it ?
Output (English): She knew it was n't going to taste right .
