Take the following as truth: Christopher Dunn related that his research interventions took 30 to 40 minutes, but his interventions outside the research arena took about 20 minutes because the process did not have to be so complicated and uniform, and there was less data collection.
Then the following statement: "A few of Christopher's research interventions went for as long as an hour." is true, false, or inconclusive?
Answer: Inconclusive
