Task: Question Answering
Input (English): Passage: Earlier today , I noticed that my kitchen floor was very dirty . Some food had been spilled on it and someone had walked across it with muddy shoes . I decided it was time to clean the floor . I swept all the dust and bits of loose dirt into the dust pan and emptied it into the garbage can . Next , I went back to the closet and got out a bucket , a mop , and a bottle of floor cleaner . I put the bucket in the bathtub and poured a little of the cleaner into it , then filled it with warm water . Starting in one corner of the kitchen , I began to mop . I soaked the mop in the cleaning solution , wrung it out , and swirled it around on the floor . I worked my way across the kitchen until the whole floor had been mopped . Then I let the floor dry . Question: How long were they mopping and dunking the mop back into the basket? Option1: until floor was clean Option2: until the floor was dirty
Output (English): until floor was clean
