@Tess_Slagle,This rule tells us that J must drive on either W or S or both but he could also drive on other days. This means that if J drives on only one out of six days, it must be either W or S, if he drives on two out of six days, then one of these days must be W or S and the second day could be either W or S or any other day. If he drives on three out of six days, one of the days must be W or S, and days 2 and 3 could be any day including W or S:
1 day: W/S
2 days: W/S + any day including W/S
3 days: W/S + any day + any day
This is a fairly open rule and allows J to drive on any day as long as one of the days he drives on includes W or S.
I have reviewed questions 14 and 19 and am not seeing any contradiction. Please let me know if there is a specific part of the explanation that is unclear.
