Step-by-step interpretation

1. E % L
   E is the brother of L

2. L # R

   L is the sister of R
   → So, E and R are siblings (since E is brother of L, and L is sister of R)

3. R + B
   R is the daughter of B
   → So R is female

---

Final relationship

• R is female

• R and E are siblings

So, R is the sister of E
