How many pairs of names below are exact duplicates?

If the count of pairs of names you identified as exact duplicates is indeed three, it reflects that there are three instances of identical names in the provided list. When counting duplicate pairs, each pair is formed by selecting two identical names, which is where the focus on pairs comes from. Hence, if you find three pairs of identical names, it suggests that you are on the right track with your assessment of the duplicates.

For example, say you identified names like "Anna Green" appearing twice, "Mike Brown" appearing twice, and "Sarah White" appearing twice. Each of these represents a distinct pair of duplicates, supporting the conclusion that there are three pairs altogether.
