Which programming structures are demonstrated by the code snippet: Repeat move forward 5 steps; If not touching Sprite 2, then Move 5 steps; Else, say "You Lose" for 3 seconds?

Which programming structures are demonstrated by the code snippet: Repeat move forward 5 steps; If not touching Sprite 2, then Move 5 steps; Else, say "You Lose" for 3 seconds?

• A. Sequencing
• B. Event-driven programming
• C. Recursion
• D. Iteration and selection

Answer: (D)

This code demonstrates iteration and selection. The loop repeats a movement action five times, showing iteration—the program performs the same action multiple times. The conditional checks whether Sprite 2 is being touched and then either moves again or displays a message for a few seconds, which is a branching decision based on a condition, illustrating selection. Because the snippet combines both repetition and a conditional choice, it best fits the idea of using iteration alongside a selection structure. It’s not about responding to external events (event-driven) or about a function calling itself (recursion), and it goes beyond plain linear sequencing by including a decision branch.
