Explanation

When Task 3 is completed in two days (ahead of schedule), it shortens or eliminates the path through Task 3, but the critical path shifts to a different, longer path through the network. Based on the referenced chart, even with Task 3 compressed to 2 days, another path through the project still totals 12 days - making that the new critical path. The critical path is always the longest remaining path, and compressing one task can reveal a previously non-critical path as the new critical path. The answer of 12 days reflects the longest path that remains after Task 3's duration is reduced.
