What is the goal of the tutorial? (00:00–00:26)

• To make a moving character in Scratch

• To create a scrolling background behind a character

• To design a platformer game in Scratch

• To create multiple backdrops in Scratch

Why can't the Scratch stage itself be used as the scrolling background? (00:26–00:54)

• It cannot be painted or edited

• It doesn’t have motion blocks

• It moves too slowly

• It cannot change costumes

What tool is used to create a sprite for the scrolling background? (00:26–00:54)

• "Choose a Sprite"

• "Paint"

• "Duplicate"

• "Add Backdrop"

What is the key to making a seamless scrolling background? (00:54–01:24)

• Adding rocks and plants

• Aligning the edges of the background sprite

• Using the "next costume" block

• Setting the X position to 0

How do you move the background sprite to the back layer? (01:24–01:52)

• By clicking the "Go to Back" button

• By using the "Go to back layer" block in the Looks category

• By dragging it behind the character

• By changing the costume

What does the X coordinate control in Scratch? (01:52–02:22)

• The height of the sprite

• The horizontal position of the sprite

• The vertical position of the sprite

• The direction the sprite is facing

How is the background made to move continuously? (02:22–02:50)

• By using "Change X by 10"

• By putting "Change X by -5" inside a forever loop

• By setting the X position to -240 repeatedly

• By duplicating the background sprite

What happens when the background sprite moves off the screen? (02:50–03:21)

• It stops moving

• It resets to the starting position

• It changes its costume

• It disappears

What block checks if the background sprite has moved off the screen? (03:21–03:50)

• If touching edge

• If X position < -460

• If Y position < -170

• If X position = 0

How is the background sprite reset to the starting position? (03:50–04:21)

• By using "Set X to 465"

• By duplicating the sprite

• By using "Go to random position"

• By changing its Y position
