No problem. That was a tough one to diagnose, but when you said that the grandparents and parents were not passing but the kids were it made it a lot easier to find.

Ahhhhhh, I see now. It looks like the code is using the incorrect single quotation mark in the word cat's in all but the children's output. Make sure to use the one that is next to the enter button on the keyboard and not the one in the top left corner of the keyboard next to the 1 button. I recommend copy and pasting directly from the conditions any output so that it matches.

cat's  // correct
cat´s  //incorrect

The failing validation says that " the line about the grandfather, grandmother, father and mother must match the conditions". Which one's?
