+This [guided tutorial](/lessons/yes-no/challenges) will show you how to display text on the micro:bit!
+

+```
+
+**Challenge 1**

+### @video vimeo/134142879
+
+Now we need to reply after someone asks Micro a  yes or no question. We want to respond `YES` when button `A` is pressed. Add a condition for button `A` and inside it show the string `YES`.
+
+```
+basic.showString("ASK ME A QUESTION", 150)
+input.onButtonPressed(Button.A, () => {
+    basic.showString("YES", 150) // ***
+}) // ***
+```
+
+* `Run` the code to see if it works as expected.
+
+**Challenge 2**
+
+### @video vimeo/134142673
+
+What if Micro's answer to the question is no? Let's have `NO` be displayed when button `B` is pressed. Add a condition for button `B` and inside it show the string `NO`.
+
+```
+basic.showString("ASK ME A QUESTION", 150)
+input.onButtonPressed(Button.A, () => {
+    basic.showString("YES", 150)
+})
+input.onButtonPressed(Button.B, () => {
+    basic.showString("NO", 150) // ***
+}) // ***
+```
+
+* `Run` the code to see if it works as expected.
+
+**Challenge 3**
+
+When you are asked a yes or no question, do you always say yes or no? Add a condition for `on shake` that displays `MAYBE`.
