Pay close attention to the sensitivity. To meet the condition for video motion, how fast do you have to move your hand?

It will never respond no matter how fast you move your hand, because the number cannot go over 100.

Only a little bit, like waving to your crush and then changing your mind.

Like a madman who is trying to get rid of a fly that refuses to go away.

You try waving your hand over the sprite, but nothing happens. What is wrong with this code?

The conditional must be inside a repeat.

The sensitivity number is too high.

The video transparency is too low.

You need to make a clone first.

Examine this flowchart. What is incorrect?

The shape of What language? is wrong.

The false arrow from the 3rd decison should point to What language?

True and False should be swapped for the decisions .

The shape of the 3 Say instructions are wrong.

You might need to include Repeat Until in order to create this program in Scratch. What is the condition for this repeat until?

Repeat until: language = english, or language = thai, or language = japanese

Repeat until: language = english, and language = thai, and language = japanese

Repeat until: language = english japanese thai

Repeat until: language = not empty

Examine this flowchart. What happens when you run this program?

It depends on what answer you give to the question.

When will the sprite stop responding to video motion?

It will stop after 10 seconds .

It will stop before 10 seconds .

It does not start in the first place.

Examine this Scratch code. How long will the timer countdown?

The timer stops after 10 seconds .

The timer stops immediately after starting .

How long will the timer countdown?

The timer stops immediately after starting .

The timer stops after 10 seconds .

How long will the timer countdown?

The timer stops after 10 seconds .

The timer stops immediately after starting .

There are 2 timers - timer 1 and timer 2. Each uses the same variable, but starts from a different broadcast. Timer 1 works, but timer 2 does not. Why not?

The repeat until condition for timer 2 is not using a variable.

Both timers must use the same broadcast message .

You must change the broadcast message of timer 2 to timer two .

The repeat until condition for timer 1 cannot be the same as timer 2 .

When will happen when timer 1 is broadcast?

The timer will stop after 10 seconds .

The timer will stop when 10 is greater than 0 .

Why does nothing happen when you run this?

The clones are deleted so quickly that they don't appear .

Scratch realizes that too many clones are going to be made, so it refuses to make any from the very start.

Show and hide are in the wrong places.

The clones are all appearing outside the screen area.

What happens when you wave your hand over a clone?

The clone hides and the score increases.

The clone ignores your hand and keeps moving forever.

On the screen, nothing is shown at the center. Why does the score increase when you wave your hand over the center of the screen?

Because the original sprite is hidden at the center and still responds to video motion.

Because an extra clone always appears at the center and gets deleted immediately.

Because the current number set for video motion is too sensitive.

Why does only one clone appear on the screen?

Because they are all stacked on top of each other at the same position.

Because they are deleted too quickly before they are shown.

Because hide and show are swapped from what is correct.

Because too many clones are created, causing Scratch to stop making them.

Examine this Scratch code.
When you click the Green Flag, you want the timer to count 5 seconds. Then, you want the sprite to move to different location. However, after 5 seconds, nothing happens.
How do you fix this mistake?

Broadcast start game must be inside repeat until, not after.

Broadcast start game must be after repeat forever.

Repeat forever should be inside repeat until.

Repeat forever should be removed.

Examine this Scratch code.
When you click the Green Flag, you want the timer to count 5 seconds. Then, you want the sprite to move to different location. However, after 5 seconds, nothing happens.
What is the reason why nothing is happening?

Broadcast start game is never sent.

The time variable never counts down.

Glide is constantly starting from the beginning, so it looks like it's not moving.

It is not your fault, because Scratch is just being weird. Like that cat with the really weird smile. So weird. Like the teacher.

MULTIPLE CHOICE QUESTION

You want the program to say who won. However, no matter what the scores are, it always skips to Thank you for playing!
How do you fix this mistake?

Put all the code, except for When I receive, into a Repeat Forever.

Add Wait 2 seconds before Say Thank you for playing!

The 2nd If Then is wrong. It should be instead:

If player 1 score < player 2 score Then

Use Broadcast Thank you for playing! instead of Say Thank you for playing!

MULTIPLE CHOICE QUESTION

30 sec • 1 pt

After about half a minute, you want the program to say Game is over!
Why is it risky to code like this?

Broadcast does not work with more than 1 receiver.

The two When I receive message1 happen at the same time. That means repeat until might stop BEFORE time is set to 30.

Repeat until is not as reliable as repeat over.

You should not set time to time - 1 inside repeat until.
