Read the following information carefully and answer the given questions. 'G % H' means 'G is the husband of H'. 'G @ H' means 'G is the wife of H'. 'G # H' means 'G is the sister of H'. 'G * H' means 'G is the brother of H'. 'G = H' means 'G is the mother of H'. 'G + H' means 'G is the father of H'. 'G ^ H' means 'G is the son of H'. 'G ≠ H' means 'G is the daughter of H'. Example: G 2% H means G is the husband of H and G has two siblings. The following is the family of Y, a married person: N 2+ P, O 1% D, A 0@ N, D 0= T, C 2# T, M 1^ A, Y 1* O, S 0≠ B, E 1* R, F 0^ R, R 1% C How is N related to R?

### Concept & Logic To find the relationship between $N$ and $R$, we need to decode the specific relational chains that connect them. This involves identifying spouses, parents, and matching the given sibling counts to merge different branches of the family tree. ### Step-by-Step Solution 1. **Decode $R$'s connections:** * `R 1% C` means $R$ is the husband of $C$. ($R$ is Male, $C$ is Female). 2. **Trace backward from $C$ to find $N$:** * `C 2# T` means $C$ is the sister of $T$, and $C$ has exactly 2 siblings. * `D 0= T` means $D$ is the mother of $T$. By extension, $D$ is the mother of $C$ as well. * `O 1% D` means $O$ is the husband of $D$. So, $O$ and $D$ are the parents of $C$ and $T$. 3. **Connect $N$ to the sibling group:** * Look at $N$'s code: `N 2+ P` means $N$ is the father of $P$, and critically, **$N$ has 2 siblings**. * Since $O$ and $D$ are parents to $C$, $T$, and one other sibling (because $C$ has 2 siblings total), $N$ perfectly fits as the third sibling in this group. * Therefore, $N$ is the brother of $C$ and $T$. 4. **Determine the final relationship:** * $R$ is married to $C$. * $N$ is the brother of $C$. * The brother of one's wife is a brother-in-law. Thus, $N$ is the brother-in-law of $R$. ### Exam Strategy & Shortcut Work backward from the target individuals. You know $R$ is married to $C$. Your immediate next goal is to find how $C$ connects to $N$. Noticing that both $C$ and $N$ have exactly 2 siblings is the key "aha" moment that proves they belong to the same sibling group under parents $O$ and $D$. ### Common Pitfall Ignoring the number attached to the symbol. The numbers (like the `2` in `C 2# T` and `N 2+ P`) are crucial for logically deducing that $N$ is the unnamed sibling of $C$ and $T$. ### Final Answer Therefore, the correct answer is **Brother-in-law**.
