Task: Question Answering
Input (English): Passage: After a day or two , the hair gets dirty . It gets harder to comb and needs to be washed . To do so , most people jump in the shower or bath and wet their hair first . Then they take shampoo and put a little bit in the hand , then rub it all over their hair . Then they wait a few seconds or a few minutes and rub the scalp as well to make sure they get rid of dandruff - some kind of dead skin . So they put another dose of shampoo in the hand and wash their hair again . Shampoo can not go in the eyes because it might burn . After the shampoo is on the head , and it has been rubbed in to clean the scalp , the most important thing is to rinse it with lots of clear warm water . The easiest way is to rub it with a dry towel , but some people like to use a hairdryer . Once the hair is dry , it can be combed any way the person likes , but it is important to avoid putting styling gels and other chemical on it too often to keep it healthy . Question: When does the shampoo make much foam? Option1: when rubbed on the arm Option2: when the hair is wet
Output (English): when the hair is wet
