What does the command 'turnLeft()' allow Karel to do?

Pick up a beeper

Change direction by 90 degrees

The command 'turnLeft()' is specifically designed to change Karel's direction by turning her 90 degrees to the left. When Karel executes this command, she rotates counterclockwise, allowing her to face a different direction without moving from her current position. This is essential for navigating the grid effectively, as Karel can only move forward while facing a specific direction. Understanding this command is fundamental for programming Karel's movements and completing tasks within the grid.

The other options focus on actions that involve picking up or dropping beepers or moving forward, which are controlled by different commands and do not pertain to changing Karel's orientation.
