Question 9
Beaver organized three forest tours and learned these tree-preference orders.
“Chuyến” means “Tour”; the less-than signs point from less liked to more liked. On a new tour Beaver wants to present these five trees in increasing preference order.
Which order avoids contradicting any earlier information?
