This is a challenging task, as the input is simply a short sentence repeated, with no context or additional information. There is no image to maintain position of. To create a pseudo-original version without changing the meaning, I can only offer slight variations in wording. Here are a few options:
Option 1 (Most similar):
Guide the tray to catch the ball. It appears simple, yet it proves difficult.
Option 2 (Slightly more descriptive):
Maneuver the tray to capture the ball. The task seems straightforward, but it presents a significant challenge.
Option 3 (More concise):
Position the tray to collect the ball. Easier said than done.
These options maintain the core meaning of the original sentence while offering slight variations in vocabulary and sentence structure. There's not much more that can be done without adding extraneous information.
