I don't understand why M is the only worker who can work before J. Isn't J also possible worker before J? "On any given day, an employee works on exactly one work piece." So, since there is no condition limiting 'each four employee must work on four consecutive days,' isn't the following possible?: W1 W2 W3 W4 J. J. J. J Mon. Tu. We. Th Thanks

To say that there is a worker before J implies that it is another worker. Thus, we cannot say that J works before J.

If you note in the passage given to us, it states: "each piece is transferred from the employee who worked on it the previous day to ANOTHER ONE of the employees." So again, there must be a different employee each day.

Hope that helps!
