Choose the option that best completes each numbered blank in the passage. Japanese people have some important eating etiquettes, especially seating. In a traditional Japanese dinner, seating arrangements are important and symbolic. On a mat, diners (26. must/ may/ could) sit on their heels with their legs tucked beneath the butt. The hosts may suggest you sit (27. formally/ comfortably/ politely),but make sure you do not spread your legs out (28. in front/ across/ behind). Which seat to take also matters. The middle of one side of the (29. chair/ table/ room) is for the host. The most honoured guest should be invited to sit (30. opposite/ behind/ beside) the host. That means he will sit in the middle of the other side of the table. The second most important guest will be seated next.
