CAFÉ. From clue 4 A must be the second letter (otherwise there would be more Xs in the previous lines as letters I, G and H are repeated). Clue 3 shows that F and E are in the answer. Clue 1 C must be first letter as D, E and A cannot be. So we now have C A _ _. From clue 2 B, D, G are not in the answer. Therefore, F and E are missing letters and E cannot be third (clue 1)
