Read the excerpt from The Building of Manhattan.
Which question can be answered only if an illustration
accompanies the text?
A temporary, small narrow-gauge track system was
installed on each floor as it was needed. This enabled
the material to be moved from the truck at ground level
onto dump carts, raised by elevator to the designated
floor, wheeled onto the track, and moved quickly to the
exact spot needed. Turntables built into the track allowed
the carts to be shifted about in any direction.
O What did turntables built into the track allow?
O How were dump carts raised to designated floors?
O When was a track system installed on a floor?
O What does a turntable built into a track look like?
