Explanation:

The author's point is that bike sharing is great because it lets people ride without worrying about buying, storing, or repairing their own bikes. Let's analyze each option:

• Option 1: "You can pick up a bike at a station for free" — The text says "for a small fee", so this is incorrect.
• Option 2: "You can check out a bike at a library" — The text mentions sidewalk stations, not libraries, so this is incorrect.
• Option 3: "You can ride a bike from one state to another" — The text is about bike stations in cities, not states, so this is incorrect.
• Option 4: "You can ride a bike without buying one" — This matches the author's point about not worrying about buying a bike, so this supports the idea that bike sharing is great.

Answer:

The correct option is the one with "You can ride a bike without buying one" (the fourth option among the given choices).
