Question 11 is a solution question so we don't actually need a sketch for it. We just need to apply the rules one at a time to the answer choices, eliminating any rules that violate them.

The next rule says that Freedom has to go to Martinique exactly twice and there has to be a voyage to Guadalupe in between. Answer choice A is okay with that, answer choice B is not fine with that. You got your M, you got your other M, but right there in the middle where there should be a G, there's a T. So B is not our answer.
And the next rule says that G has to be the destination in the week preceding any voyage it makes to Jamaica. In A, there's Jamaica, there's Guadalupe right in front of it, its fine. In C we have Jamaica first, which can never happen because there's no way to go to Guadalupe first. So answer choice C is not our answer, that only leaves answer choice A.
