Question

assuming that the list months contains exactly 12 elements, what would happen when the script below is run? insert thing at 19 of months blank entries will be added to the list months so that the new element thing can be inserted at index 19. the element thing will be added to the beginning of the list months. the list months will remain unchanged. the element thing will be added to the end of the list months.

Explanation:

In programming (related to Computer Science, a subfield of Natural Science), when inserting into a list at an index beyond the current length, most list implementations (like in many programming languages) will add the element at the end if the index is out of bounds (or handle it by appending, as inserting at an index larger than the list length typically results in appending). The list months has 12 elements (indices 0 - 11). Inserting at index 19 is beyond the current length, so the element "thing" will be added to the end. Let's analyze the options:

• First option: Lists don't add blank entries to reach a specific index; this is incorrect.
• Second option: Inserting at index 19 isn't the beginning (index 0), so incorrect.
• Third option: The list will change as we're inserting an element, so incorrect.
• Fourth option: Since the index 19 is beyond the list's length (12 elements, max index 11), the element is added to the end of the list.

Answer:

D. The element thing will be added to the end of the list months.
