// MISSION BRIEF
Your Mission
The element you need is three screens down. Every mobile framework has an answer, and each answer has a trap: directions that mean opposite things, gestures that overshoot, one-liners that scroll AND find. This quiz covers the scroll toolbox that mobile test authors reach for daily.
Six questions. Speed bonus active.

Battle teaser
driver.execute_script('mobile: scrollGesture', {...}) on UiAutomator2 takes:
- AOnly a pixel pair: start and end coordinates
- BA CSS selector to scroll to
- CNo arguments; it always scrolls one page down
- DAn area (left/top/width/height) or an elementId, plus direction and percent, and RETURNS a boolean: whether more scrolling is possible, so you can loop until the target appears or the scroll runs dry
Answers, scoring, hints, and the full battle stay sealed.
