What is the purpose of the onMouseMove event?

• It is called when the mouse is clicked.

• It is called every time the mouse is moved and not pressed.

• It is called when the mouse is double-clicked.

• It is called when the mouse is stationary.

When is the onMouseDrag event triggered?

• When the mouse is moved without pressing.

• When the mouse is pressed and moved.

• When the mouse is clicked once.

• When the mouse is double-clicked.

What does an if statement do?

• Runs code only if a test is false.

• Runs code only if a test is true.

• Runs code regardless of any test.

• Runs code only if a test is undefined.

Which operator checks if x is less than y?

• x > y

• x <= y

• x < y

• x == y

Which operator checks if x is equal to y?

• x != y

• x == y

• x = y

• x > y

What does the operator x != y check?

• If x is greater than y.

• If x is less than y.

• If x is not equal to y.

• If x is equal to y.

Which statement best describes how the "else" part of a conditional statement works? (See the example conditional statement.)

• It runs if the condition in the if statement is true.

• It runs if the condition in the if statement is false.

• A function that runs automatically.

• A function that helps another function perform its work.

• A function that cannot be called from other functions.

• A function that does not take parameters.

What is the purpose of using multiple if statements in a row?

• To test the same condition multiple times.

• To test different conditions.

• To ensure the code never runs.

• To make the code run faster.

Which of the following tests if x and y are equal?
