# love meter blocks quiz answers
The answers to the love meter quiz.
This is the answer key for the [love meter quiz](/lessons/love-meter/quiz).
## 1. What does `on pin pressed(P0)` do?
<br/>
It's a method that runs code when the user holds the GND pin with a finger of one hand and presses pin P0, completing a circuit.
## 2. Write the code.
Create a condition for `on pin pressed (P0)`.
```blocks
input.onPinPressed(TouchPin.P0, () => {
})
```
## 3. What does this line of code doing?
```blocks
let x = Math.random(9)
```
It stores random number between 0 and 9 then stores that number in a variable.
## 4. Why do you have to add 1 to variable x?
```blocks
let item = 0;
item = 0;
basic.showNumber(item + 1);
```
You have to add 1 if you want to generate a random number between 1 and 10 .
## 5. Why do you have to hold ground (GND) to make this work on the micro:bit?
You have told GND to complete the circuit.
