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 following is invoked: | Level 8 Level 9 Cannot go up. Level 9 |

Frankie is considering whether to use a binary or linear search in her program to find a value in a sorted list. When she tests the algorithms on selection of short lists of fixed-length lists she finds that the binary search is faster on average than the linear search. Another programmer suggests she tests both algorithms on a selection of lists which are 10 times as long as her original test lists. Which of the following best describes the likely results of this test? | The binary search will still be faster on average than the linear search, and the difference in run times between the two searches will be significantly more than 10 times greater than for the shorter lists. |
Sally notices that she has the same set of 10 blocks in her code in multiple places. She decides to create a new block (procedure) in Scratch so that she can simply replace those 10 blocks with one procedure. Which of the following gives the best ways in which this could be beneficial to Sally when she debugs and reasons through her program? Select two answers. | If there is an error in the procedure, she can fix the error in the procedure without having to search through her code for each place the procedure is used. |
