What causes Emmie to crash when going down the ramp?

Emmie crashing while going down the ramp is primarily due to a sudden distraction that causes her to lose her concentration. When the sun reflects off of Devontae's belt buckle, this unexpected flash diverts her attention away from navigating the ramp safely. This momentary loss of focus is critical; it indicates that external environmental factors can significantly impact one's performance, particularly in high-stakes situations. Being unable to maintain concentration at such a vital moment leads directly to her accident. While other factors, like the steepness of the ramp or physical interference from others, might seem relevant, the direct cause of her crash in this context is the unexpected distraction.
