Show the correct answer
Correct answer
C. Top up the sandboxes at the nearest end.
Explanation
In the photo you can see the filler opening of a sander tank on the side of a tram. If there is no sand in the tanks, you should refill the sanders with special sand at the nearest terminus - answer C.
Sanders need dry sand of the right grain size - only this kind of sand flows through the pipes and improves grip. Gravel (answer B) would block the sander and could damage the wheels and the rails. Stopping the tram on the route (answer A) is not necessary, because the tram can safely get to the terminus. Until then, you drive more carefully, especially on slippery rails. You always check the level of sand in the tanks before going out on the line.
