Explanation:

- D ^ B $ E: D and E are married, with B as the father of E.

- B % K * L: B is the son of K, and K is the grandmother of L.

- E ^ G + L: E and G are married. G is L's sister-in-law.

- B % M: B is the son of M.

To figure out the blanks:

- L = P: Means P is L's brother.

- To satisfy the condition where N is the nephew of P, N must be the son of one of P's siblings.

- G # N: G is the mother of N.

Therefore, if:

- L is the sibling (P), P @ (brother-in-law) G, and N % (son of) E,

or

- L is the sibling (P), P + (sister-in-law) G, and N % (son of) E,

Both configurations satisfy the conditions.

So, the statement becomes:

1. L = P @ G # N % E ?

2. L = P + G # N % E
