A group of children is arguing what day it is today. A says: Today is not Sunday; B says: Today is Friday; C says: The day before yesterday is Saturday; D says: Yesterday is Tuesday; E says: Today is Tuesday; E says: Today is not a week Monday, not Tuesday, not Wednesday. In fact, only one of them was right. Ask what day is today? ['Tuesday.', 'Thursday.', 'Saturday.', 'Sunday.']
