-# offset image challenges
-
-Coding challenges for the offset image tutorial.
-
-## Before we get started
-
-Complete the following exercise. Your code should look like this:
-
-```blocks
-offset = 0
-basic.forever(() => {
-    if (offset == -4) {
-        basic.showString("Push button A", 150)
-    }
-    images.createImage(`
-. . # . .
-. . # . .
-. . # . .
-. # # # .
-. . # . .
-`).showImage(offset)
-})
-input.onButtonPressed(Button.A, () => {
-    offset = offset + 1
-})
-```
-
-### Challenge 1
-
-Create a condition for if button `B` is pressed. We want the image to move to the left when button `B` is pressed.
-
-```
-offset = 0
-basic.forever(() => {
-    if (offset == -4) {
-        basic.showString("Push button A", 150)
-    }
-    images.createImage(`
-. . # . .
-. . # . .
-. . # . .
-. # # # .
-. . # . .
-`).showImage(offset)
-})
-input.onButtonPressed(Button.A, () => {
-    offset = offset + 1
-})
-input.onButtonPressed(Button.B, () => {
-    offset = offset - 1 // ***
-}) // ***
-```
-
-* Run the code to see if it works as expected.
-
-### Challenge 2
-
-
-
-Now we want to make sure that the button does not go off the screen to the right. Add a new line that checks to see if offset = 5 after button `A` is pressed.
-
-If `offset = 5` then prompt the user to move the image to the left by displaying the text: "Push button B".
-
-```
-offset = 0
-basic.forever(() => {
-    if (offset == -4) {
-        basic.showString("Push button A", 150)
-    }
-    if (offset == 5) {
-        basic.showString("Press Button B", 150) // ***
-    }
-    images.createImage(`
-. . # . .
-. . # . .
-. . # . .
-. # # # .
-. . # . .
-`).showImage(offset)
-})
-input.onButtonPressed(Button.A, () => {
-    offset = offset + 1
-})
-input.onButtonPressed(Button.B, () => {
-    offset = offset - 1
-})
-```
-
-* Run the code to see if it works as expected.
-
-### Challenge 3
-
-Now make sure the image does not go off the left side and if it does, prompt the user to push button `A`.

-# offset image quiz answers
-
-shift an image horizontally across the display with offset.
-
-This is the answer key for the [offset image quiz](/lessons/offset-image/quiz).
-
-## 1. What is a 'if, then, else statement' ? 
-
-<br/>
-
-An if-then statement will run a block of code if the condition specified is true. The statement will run the "else" block of code if that condition is false.
-
-## 2. Consider the message
-
-Write the line of code that that will create the message "Push button A" (Hint: This message appears `if` the offset is equal -4 then the BBC micro:bit will state "Push Button A").
-
-<br/>
-
-```
-if (offset == -4) {
-    basic.showString("Push Button A", 150)
-}
-```
-
-## 3. Consider the following image
-
-![](/static/mb/lessons/offset-image-0.png)
-
-When with this image be displayed?
-
-<br/>
-
-When the offset is NOT equal to -4 then the BBC micro:bit will show the image above.
-
-## 4. Consider the following image
-
-![](/static/mb/lessons/offset-image-1.png)
-
-Write the two lines of code that cause the `variable` offset to increase by one when button `A` is pressed.
-
-<br/>

-```
-input.onButtonPressed(Button.A, () => {
-    offset = offset + 1
-})

 First, notice that moving the 1st micro:bit in the simulator in any direction, you will change the acceleration value of the 2nd micro:bit. Also, notice that by moving the micro:bit simulator, there is a changing acceleration value of the second micro:bit. Second, the flat colored horizontal line will start a waving line on the 2nd micro:bit to display the value of the strength as measured in milli-gravities. Finally, notice that the LED display will fluctate based on the movement of the 2nd micro:bit simulator.
