What is the primary advantage of using Merge Sort over Quick Sort?

Step 1: Understand what sorting algorithms are. They are methods used to arrange data in a specific order.
Step 2: Learn about Merge Sort. It divides the data into smaller parts, sorts them, and then merges them back together.
Step 3: Learn about Quick Sort. It also sorts data but does it by selecting a 'pivot' and arranging other elements around it.
Step 4: Identify what 'stable sorting' means. A stable sorting algorithm keeps equal elements in the same order they appeared in the original list.
Step 5: Recognize that Merge Sort is stable, meaning it preserves the order of equal elements.
Step 6: Note that Quick Sort is not stable, which can change the order of equal elements.
Step 7: Conclude that the primary advantage of Merge Sort over Quick Sort is its stability.
