Final answer:
To express that M is the maternal grandmother of T, we look for the sequence that shows M as the mother (x) of N, and N as the parent (+) of T. The correct answer is A. M x N + S + T, meaning M is the mother of N, and N is the parent of T.
Step-by-step explanation:
The question involves interpreting a set of symbols that represent different family relationships to determine how M can be represented as the maternal grandmother of T. We can break down the options provided and find the correct representation based on the meanings assigned to the symbols:
- A + B means A is the father of B
- A - B means A is the brother of B
- A · B means A is the wife of B
- A x B means A is the mother of B
For M to be the maternal grandmother of T, M must be the mother of T's mother. Therefore, we need to find a sequence where M is the mother (x) of someone (N), and that someone (N) is the parent (+) of T.
The correct answer is A. M x N + S + T. This translates to M is the mother of N, who is then the parent (in this case, presumably the mother to maintain the maternal line) of T.
