State Route 360 (SR 360) is a state highway in the southern portion of Mineral County, Nevada, United States. The route connects the former town of Basalt to the rest of Mineral County. A road has been in the place of SR 360 since 1919, and became State Route 10 by 1929.
State Route 360 is longer than SR 360.
It's definitely incorrect because they refer to the same thing, so it can't be longer than itself. It's difficult because the text never mentions length, so the system thought it was unanswerable.
