A student wrote the following code segment, which displays true if the list myList contains any duplicate values and displays false otherwise.

The figure presents four blocks of code that consists of 10 lines. Throughout the blocks of code there are nested blocks of code, as follows. Line 1: [Begin Block] containsDuplicates ← false [End Block] Line 2: [Begin Block] j ←1 [End Block] [Begin Block] Line 3: REPEAT UNTIL [Begin Block] j greater than LENGTH [Begin Block] myList [End Block] - 1 [End Block] [Begin Block] Line 4: [Begin Block] k ← j + 1 [End Block] Line 5: [Begin Block] REPEAT UNTIL [Begin Block] k greater than LENGTH [Begin Block] myList [End Block] [End Block] [Begin Block] Line 6: [Begin Block] IF [Begin Block] myList [Begin Block] j [End Block] = myList [Begin Block] k [End Block] [End Block] [Begin Block] Line 7: [Begin Block] containsDuplicates ← true [End Block] [End Block] [End Block] Line 8: [Begin Block] k ← k + 1 [End Block] [End Block] [End Block] Line 9: [Begin Block] j ← j + 1 [End Block] [End Block] [End Block] Line 10: [Begin Block] DISPLAY [Begin Block] containsDuplicates [End Block] [End Block]
The code segment compares pairs of list elements, setting containsDuplicates to true if any two elements are found to be equal in value. Which of the following best describes the behavior of how pairs of elements are compared?
