Which configuration has two straight sections with a flat intermediate landing?

• A. Stairway Chairlift
• B. Power Source
• C. Flat Curve
• D. Battery Backup

Answer: (C)

Two straight sections with a flat intermediate landing describe a path that stays level between the straight runs, creating a flat platform between them. This layout is called a flat curve, because the intermediate platform remains flat as you move from one straight section to the next rather than curving or stepping up and down. It’s the best fit because it directly matches the description of a level landing between straight segments, which is a layout concern, not a power or equipment feature. The other options refer to equipment or power aspects—stairway chairlift is a different type of transport device, while power source and battery backup describe where and how the system is powered, not the physical path configuration.
