问答题 Implausible though it seems, three students named Andrew, Colin and Brian have a rota of household chores for Monday, Tuesday and Wednesday. If Andrew"s task is on Tuesday, but is not the ironing, and the dusting is carried out later in the week than Brian"s gardening, what does each do and on which day?

【正确答案】

【答案解析】Colin，Ironing，Wednesday；Andrew，dusting，Tuesday；Brian，gardening，Monday[解析] (因为在Brian收拾完花园(gardening)后，才有人做清扫(dusting)，所以Brian不可能在周三做家务。因为Andrew在周二做家务，所以Brian是在周一做，那么Colin就是在周三做。Brian收拾花园，Andrew不熨烫衣服(ironing)，证明Andrew的工作是清扫，那么Colin的工作就是熨烫。)
