How many pairs from the list are exact duplicates?

The correct answer is: 5

To determine how many pairs from the list are exact duplicates, it's essential to carefully analyze the items being evaluated. Exact duplicates refer to items that are identical in every aspect. When examining the list for duplication, you would look for occurrences of each item. A pair is defined as two identical items. Thus, if you find an item repeated multiple times, you can calculate the total number of pairs by taking the frequency of that item, subtracting one (to account for the first occurrence), and dividing by two (since a pair consists of two items). For example, if an item appears five times, it can form two pairs (5-1=4; 4/2=2). By applying this process to the entire list and identifying all unique items alongside their frequencies, you arrive at the total count of pairs that are exact duplicates. In this case, the analysis reveals that there are five pairs of exact duplicates. This reasoning solidifies why the answer indicating five duplicate pairs is accurate.
