Explanation: A is mother of B. C is husband of B, so C is the son-in-law of A. D is sister of C, so D is the sister of B's husband. E is mother of D, so E is the mother of C (and therefore the mother-in-law of B). F is father of E, so F is the father of C's mother. Therefore F is the grandfather of C. G is son of B and C. Since C is the son of E and F, C is the grandson of F. G is the son of C, so G is the great-grandson of F (son of F's grandson). Therefore G is the great-grandson of F.

S ↓ T means S is the daughter of T, so T is the parent of S. Since R and S are siblings and T is the parent of S, T is also the parent of R. Therefore R, S, and T are children of T. Q is the wife of R. P is the father of Q. Since Q is the mother of R's children, and P is the father of Q, P is the grandfather of R's children. Thus P is the grandfather of T.
Explanation: A is the mother of B and C. D is the father of C, so D is the father of B and C. E is the wife of D, so E is the mother of B and C. F is the son of A.
