Take the following as truth: In a rare opportunity for concentrated effort by one man on such a gigantic project, Bernini completed the 284 travertine columns, 88 pilasters, and 140 statues of the saints in just 11 years, from 1656 to 1667.
Then the following statement: "It took Bernini 11 years to finish the project." is true, false, or inconclusive?
