Use the following problem statement to answer questions $1-5.$

Chris wants to develop a workforce schedule for the staffing requirements in the table, giving workers two consecutive days off per week. There are two preferences that he will use to break ties in the selection of two days off. The first preference is the S$-$Su pair. The second preference is the earliest pair in case of a tie, indicating Tuesday is the first working day of a week. The first preference is more important than the second one. He wants to develop a workforce schedule for these individuals so that each will have $2$ consecutive days off per week and all staffing requirements will be satisfied.
