**Challenge 0**
This [guided tutorial](/lessons/yes-no/challenges) will show you how to display text on the @boardname@!
```
basic.showString("ASK ME A QUESTION", 150)
```
**Challenge 1**
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**
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`.
