Why is the following command an invalid Karel command? turnleft();

Which of the following is the correct way to define a turnRight function in Karel? Options: function turnRight() { turnLeft(); turnLeft(); turnLeft(); }, function turnRight() { turnRight(); turnRight(); turnRight(); }, function turnRight { turnLeft(); turnLeft(); turnLeft(); }, turnRight function() { turnLeft(); turnLeft(); turnLeft(); }

Why do we use functions in Karel programs?

If Karel starts at Street 1 and Avenue 1, facing East, where will Karel be, and what direction will Karel be facing after running the following code? (Assume the world is 10x10 in size)

Karel starts at Street 1 and Avenue 1, facing East. After calling the stairStep function twice, where will Karel be and what direction will Karel be facing?

In this code, how many times is the dance function called and how many times is it defined? Options: Called 1 time, defined 1 time; Called 1 time, defined 3 times; Called 3 times, defined 1 time; Called 3 times, defined 3 times

What’s wrong with this code?

How many total times will Karel move in this program?

What is wrong with this for loop? for (var i = 0, i < 10, i + 1) { move(); } I. The for loop uses commas instead of semicolons II. It should say i++ instead of i + 1
