Oliver Lehmann may be able to explain this by himself
The question has meanwhile moved to become #18 at http://www.oliverlehmann.com/pmp-self-test/75-free-questions.htm.
Free float is the time that an activity can be delayed without impacting another activity. Activity B can be delayed by 9 days without impacting Activity D, which is intended to start on the morning of the tenth day after (early) finish of Act. B.
Total float is the time difference between early start and late start or early finish and late finish dates. In the example, this is 10 days for Act. B.
Act. A has a free float of 0 and a total float of one day.
Once you understand the concept, it is actually rather simple and straight forward.
Recommendation: Don't try to sit for the exam without a sound understanding of network diagramming. Some people consider it a core competency for a project manager, and these people may be among those who write questions for the test.
