+// EXERCISE: Simplify It
+//
+//  Can you simplify the if statement inside the code below?
+//
+//  When:
+//    isSphere == true and
+//    radius is equal or greater than 200
+//
+//    It will print "It's a big sphere."
+//
+//    Otherwise, it will print "I don't know."
+//
+// EXPECTED OUTPUT
+//  It's a big sphere.
+// ---------------------------------------------------------
+
+func main() {
+	// DO NOT TOUCH THIS
+	isSphere, radius := true, 100
+
+	var big bool
+
+	if radius >= 50 {
+		if radius >= 100 {
+			if radius >= 200 {
+				big = true
+			}
+		}
+	}
+
+	if big != true {
+		fmt.Println("I don't know.")
+	} else if !(isSphere == false) {
+		fmt.Println("It's a big sphere.")
+	} else {
+		fmt.Println("I don't know.")
