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 ?
Answer: She knew she is unable to eat it because of her diet .She knew it was n't going to taste right .None of the above choices .She knew she was being poisoned .
