Maria is Carlos's mother, and Sofia is Carlos's daughter. This makes Maria Sofia's grandmother because the mother of one's father is their grandmother. Jose is Maria's husband and Carlos's father; therefore, he is Sofia's grandfather, as a father's father is called a grandfather. Carlos is not Jose's nephew because Carlos is Jose's son. In a family tree, a nephew is the son of a person's sibling, not their own child.
If Jose is Maria's husband, and they have a son named Carlos, how would Maria be related to Sofia, who is Carlos's daughter? Also, what would Jose's relationship to Sofia be, and why isn't Carlos Jose's nephew? Make your response very short.
