Hint 3 of 3
Whoever is left after you label Anna, Josef and Bob, and who fits the giving clue, is Barbara.
Show solution
Approach: label the children you know, then the leftover picture matching the giving clue is Barbara
- First label the pictures the clues hand directly to Anna, Josef and Bob.
- The remaining clue says Barbara gave Eva her item, which points to one specific picture.
- That picture is option D, so Barbara is D.
