Consider the above code segment that is designed to print all numbers from a list of integer values, called grades, that are between 90 and 100, inclusive.
Which of the following modifications can be made to the code to allow it to also print numbers from a variety of different ranges of values (e.g., 70 to 80, 85 to 95, 1 to 50, etc.)?

A large office building has an elevator that carries occupants between any of the building's 10 floors. The basement is referred to as "Level 0" while the topmost floor is "Level 9." The software for the elevator uses a variable, called level, to track the floor number of the elevator's current position. When a person presses a button requesting the elevator to rise to a higher floor, the above code is executed.
What is displayed if the elevator is currently on the 7th floor (level = 7) and the person on the elevator presses a button that says to go up 3 floors (floors = 3)?
Level 7 Level 8 Level 9
Level 8 Level 9 Cannot go up. Level 9
Level 8 Level 9 Level 10
