To understand what will happen when the provided code runs, let's break down the movements and turns step by step.
1. **Karel starts at Row 1, Column 1, facing East.**
2. **First command:** `move();`
- Karel moves one space East to Row 1, Column 2.
3. **Second command:** `move();`
- Karel moves one space East to Row 1, Column 3.
4. **Third command:** `turnRight();`
- Karel is now facing South (since Karel was initially facing East).
5. **Fourth command:** `move();`
- Karel moves one space South to Row 2, Column 3.
After executing all the commands, Karel will end up at Row 2, Column 3.
So, the correct answer is:
**Karel ends on Row 2, Column 3.**
