Mary's father has 4 children; three are named Nana, Nene, and Nini. So what is the 4th child's name?
Common Wrong Answers
“Nono”
This guess follows the pattern of the previous names but ignores the key detail in the riddle that states 'Mary's father' which indicates that Mary is the fourth child.
“Nina”
Nina seems to fit the naming pattern but does not take into account that the riddle clearly states that Mary is one of the children.
“Nina”
While Nina follows the phonetic pattern, it overlooks the explicit mention of Mary being one of the children, making it an incorrect answer.
