Multiple Choice

Which configuration is described as 'Standard gauge multiple track'?

Explanation:
Gauge and track configuration in rail systems are being tested here. Gauge is the distance between the two rails; standard gauge, about 1,435 mm, is the most widely used width. “Multiple track” means there are several parallel rails, which allows more traffic and trains to pass without waiting for single-track sections. So the description “Railroad – Standard gauge multiple track” fits a railroad built on standard gauge with more than one parallel track. The other options don’t fit because a narrower gauge would be stated as narrow gauge, a single track lacks the multiple rails, and a mine dump isn’t a railroad configuration.
