Which statement correctly contrasts hinge-type swing gates with track-driven sliding gates regarding installation considerations?

• A. Swing gates require space to swing and strong posts; Sliding gates need a track and wheel assemblies with proper alignment and ground clearance.
• B. Swing gates require a track and wheel assemblies; Sliding gates require space to swing.
• C. Swing gates require space to swing and strong posts; Sliding gates need a track and wheel assemblies with proper alignment and ground clearance.
• D. Both have identical installation requirements.

Answer: (C)

Swing gates move by rotating on hinges attached to sturdy posts, so the installation must provide enough space for the gate to swing open without colliding with obstacles and ensure the posts and hinges are robust enough to handle the forces involved. Track-driven sliding gates, on the other hand, move along a fixed path on wheels, so the setup centers on a properly laid track with correctly aligned wheel assemblies and sufficient ground clearance to avoid rubbing, binding, or derailment. This difference in movement and support needs is what makes the stated contrast the correct one.
