Can someone explain section 1 Q 15 to me on the 7Sage practice test? I'm really struggling. Here's my logic:

W1: G (by rule)

W2: T (by rule)

W3: can't be G because G must come directly before J and J can't be W4

W4: Cant be J (by rule)

W5: Must be G (by rule)

W6: Must be J (has to be one stop min)

W7: T (by rule)

This only leaves Martinique x2 for weeks 3 and 4. But the rules state G must take place between those 2 trips....

Help....please! lol
