QUESTION 4 Step 1: Identify the starting and ending floors. The top level is Floor 5. The bottom level is Floor -4 (4 floors below ground level). The tourist starts at Floor 5 and travels to Floor -4. Step 2: Determine the floors where the tourist will stop. The tourist stops every 2 floors while moving downwards from Floor 5. • From Floor 5, the first stop is at Floor 5 - 2 = 3. • From Floor 3, the second stop is at Floor 3 - 2 = 1. • From Floor 1, the third stop is at Floor 1 - 2 = -1. • From Floor -1, the fourth stop is at Floor -1 - 2 = -3. The next stop would be at Floor -3 - 2 = -5. However, the lowest floor in the store is Floor -4. Therefore, the lift will travel directly from Floor -3 to Floor -4 without an additional intermediate stop. The destination (Floor -4) is the end of the journey, not an intermediate stop for "looking around briefly". Step 3: Count the number of stops. The stops made are at Floor 3, Floor 1, Floor -1, and Floor -3. This is a total of 4 stops. The tourist will make 4 stops. Last free one today — make it count tomorrow, or type /upgrade for unlimited.
