Which of the following features allows for easier navigation of long lists on a tablet device?

Pinch-zoom is a two-finger gesture used to zoom in or out on content and does not assist with scrolling through a list.

Multitouch is the general capability of a screen to detect multiple simultaneous touch points; it is the underlying technology, not the specific navigation feature.

Scrollbars are a traditional GUI element that require precise tapping or dragging on a small target, which is less efficient and less natural than gesture-based touch flow on a tablet.

Touch flow allows a user to flick a list and have it continue scrolling with decreasing speed, simulating physical momentum. This enables rapid traversal of long lists with a single gesture and is a core usability feature of tablet and touchscreen interfaces.
