Where is the Y-Junction located?

• A. Jefferson street or central stations
• B. Bay and Jefferson streets
• C. Central and Bay streets
• D. San Marco Street

Answer: (B)

A Y-junction happens where two streets meet at a point to form a fork-like intersection. The option that names Bay Street and Jefferson Street fits this idea best, since it describes the crossing of two streets that would create the Y-shaped junction. The other choices either reference a single street with something unrelated, or mix in terms that don’t describe an actual street intersection, so they don’t match the concept of two streets converging to form the Y shape.
