Premise:
"While Plotz is right that the number of challenges remaining seems to be decreasing--it could hardly increase--I find it almost impossible to believe that previous record-setters were driven by the kind of practical, commercial concerns that Plotz ascribes to Ferdinand Magellan and Dick Rutan." Based on this premise, is the hypothesis "Plotz hasn't made any observations about Magellan's motives." true?
