Street 6 and Avenue 2

Answer 1

Let’s analyze Karel's movements step by step, starting from Street 1 and Avenue 3 while facing East:

1. **Starting Position**: Street 1, Avenue 3 (facing East)
2. **move()**: Karel moves forward from Street 1, Avenue 3 to Street 1, Avenue 4 (still facing East).
3. **move()**: Karel moves forward from Street 1, Avenue 4 to Street 1, Avenue 5 (still facing East).
4. **move()**: Karel moves forward from Street 1, Avenue 5 to Street 1, Avenue 6 (still facing East).
5. **turn_left()**: Karel turns left, changing direction from East to North.
6. **move()**: Karel moves forward from Street 1, Avenue 6 to Street 2, Avenue 6 (now facing North).

So after executing the code, Karel ends up at Street 2 and Avenue 6.

The correct answer is:
**Street 2 and Avenue 6**.
