Why my process finally left cocoa and tea and two blanks, one is what French carries, the other is what Brazilian carries. Assigning cocoa or tea to either blank seems OK.
What is wrong?

Hi jiaoqian, and welcome to the Forum!
I did this puzzle many years ago, and, like you, could not resolve the French/Brazilian cocoa/tea issue.
That means there are two solutions, which, for me, is disappointing.
I've done many of these types of logic puzzles, and the Ships Puzzle is one of the very few I've come across that has multiple solutions...

I tried it yesterday and got this result too.
For this sort of puzzle I'd prefer a single solution but sometimes in life there is more than one. The solution page does acknowledge the alternatives.
Can anyone find a simple edit that makes the solution unique? **

Hi Bob;
Can anyone find a simple edit that makes the solution unique?
Here's a simple edit to Clue 5 that produces a unique solution by replacing 'To the right of' with 'Next':
5. Next to the ship carrying cocoa is a ship going to Marseille.
Clues 7, 11 & 14 also use 'next'.
