Answer 1

To make Karel move 6 times and then put a ball, the most appropriate control structure to use would be a **For loop**.

A For loop allows you to iterate a specific number of times, which in this case would be exactly 6 times for Karel to move. After the loop, you can then have Karel put down a ball.

Here’s a simple example of how you could structure this in pseudo-code:

```plaintext
for i from 1 to 6 do
move()
end for
putBall()
```

In this example:
- The `for` loop iterates 6 times, causing Karel to move 6 times.
- After the loop has completed, Karel puts down the ball.

So, the answer is **For loop**.
