How many choices are possible when using a single if-else statement?

Back

2

Answer explanation

A single if-else statement provides two possible paths: one for when the condition is true (if) and another for when it is false (else). Therefore, the total number of choices is 2.

What shape will this program draw? Options: a spiral design, a square, a circle, a triangle

Back

a square

Answer explanation

The program is designed to draw a square, as it typically involves moving in straight lines and turning at right angles, which are the defining characteristics of a square. Other shapes like circles or triangles are not formed by this method.

How can you order these blocks so that your robot begins to move three blocks to the right as fast as possible?

Back

Front

Which of these blocks do you need to draw a straight vertical line? Options: Put pen up and drive forward, Put pen down and drive forward, Put pen down, turn right and drive forward, Put pen down and turn right

Back

Put pen down and drive forward

Answer explanation

To draw a straight vertical line, you need to put the pen down and drive forward. This action allows you to create a continuous line in a vertical direction without any turns.

What does this code look like it is doing?

Back

It will make the robot walk forward one block then reverse and repeat 10 times, increasing the amount of blocks by 1 every time

Answer explanation

The correct choice describes a sequence where the robot walks forward one block, then reverses, and this process repeats 10 times, increasing the distance by 1 block each time, which matches the provided code behavior.

This program has a problem. It will not draw a line. Which line number is the cause of this problem? (Lines are indicated by red circles.)

Back

Line 2

Answer explanation

Line 2 is likely the cause of the problem because it may contain an error in the drawing logic or parameters that prevents the line from being rendered. Checking this line can help identify the issue.

What will the robot do if it detects a green object close by?

Back

Turn left 90 degrees

Answer explanation

The robot is programmed to turn left 90 degrees when it detects a green object nearby. This response helps it navigate effectively around obstacles or follow specific paths.

Front

What will happen if the Front Eye Sensor detects green in this project?

Back

The VR Robot will turn right for 90 degrees.

Answer explanation

When the Front Eye Sensor detects green, the VR Robot is programmed to turn right for 90 degrees. This response is part of its navigation logic to avoid obstacles or follow a path.

What is the purpose of the gray comment blocks?

Back

They make the program easier to read and more organized for the programmer.

Answer explanation

The gray comment blocks serve to make the program easier to read and more organized for the programmer, providing clarity and context without affecting the robot's execution of commands.
