Task: Question Generation
Input (English): Context: No staining ! If you look closely at the first sample with the oil on it , you may see , on the unoiled part , a few white marks which are scratches . After I wiped off the oil on the sample with dishwashing soap and water on a sponge and brushed the slate using the opposite side of the sponge fairly roughly , " wah laaa " the white spots disappear ! If they do not completely disappear , then it is my understanding ( although I have not done it myself ) that one can lightly sand any significant white scratches and they will disappear .
Output (English): What am I explaining in this scenario ?
