Sol 1: The first sentence is USI while all other are is actual information. Since, as suggested above we should begin with the parent-child relationship. And the third sentence depicts parent-child relationship i.e. D is the only son of C who’s a brother of A. Therefore, the diagram is as follows
Now we should look info. that tells more about A, D or C. The second sentence tells us more about A. So, we’ll incorporate that into the diagram.
Now we shall add the leftover information and the one that fits the most in the current diagram is the relationship between D and E.
We have finally reached in the position of completing our tree diagram by incorporating the final information which is about F who is a female since her husband had died. And B is her daughter-in-law. Therefore, she’s the mother of A and C.
