Which one of the following must be true about Freedom's schedule of voyages?

Guadalupe and Jamaica same rule

If the proper answer is Because Jamaica can’t be placed more than twice because it’s paired with Guadalupe, wouldn’t that mean answer C would also be correct?

Hello @Claude,

I believe this is the rule you are referring to: Guadalupe will be its destination in the week preceding any voyage it makes to Jamaica.

You referred to it as a pairing between Jamaica and Guadalupe, but that is not quite true. The rule requires that any time there is a trip to Jamaica, there must be a trip to Guadalupe immediately before it. However, that does not mean that every trip to Guadalupe is immediately followed by a trip to Jamaica.

It is possible to have 3 voyages to Guadalupe and 1 voyage to Jamaica. Take a look at this example.

Does this violate the rule mentioned above? No, because every voyage to Jamaica (week 3) is preceded by a voyage to Guadalupe. Answer choice C is incorrect because it is possible for Freedom to make more than two trips to Guadalupe.
