+# 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.
