Explanation: 1) "Daniel has no brothers." The people listed are a father, mother, two sisters, and a brother. We do not know if the father has brothers, but we do know of the siblings, there is only one boy. Considering the data given, Daniel must be the brother. 2) "Morgan is not Kayla's mother. She is also not Kayla's father." From this we can derive that Morgan is female, but she is not the mother. Therefore, she must be the younger sister. 3) I do not know if clue 2 was supposed to be about Devin, not Daniel, but I assume based on current naming trends that Grace is still a female name and Devin and male name. Therefore, having established both siblings, Grace must be the mother, and Devin the father. (Note: I expect clue 2 was meant to read "Devin likes to jog. He jogs every morning." This would establish gender for Devin. Otherwise, there is no way to absolutely say which of Grace and Devin was mother, and which was father.) Daniel is the younger brother, Morgan is the younger sister, Grace is the mother, and Devin is the father.

Explanation:
1) “Daniel has no brothers.” The people listed are a father, mother, two sisters, and a brother. We do not know if the father has brothers, but we do know of the siblings, there is only one boy. Considering the data given, Daniel must be the brother.
2) “Morgan is not Kayla’s mother. She is also not Kayla’s father.” From this we can derive that Morgan is female, but she is not the mother. Therefore, she must be the younger sister.
3) I do not know if clue 2 was supposed to be about Devin, not Daniel, but I assume based on current naming trends that Grace is still a female name and Devin and male name. Therefore, having established both siblings, Grace must be the mother, and Devin the father.
