Take the following as truth: This collection of nine centuries of paintings includes important works by Giotto, Fra Angelico, Perugino, Raphael's Transfiguration (his last great work), Leonardo da Vinci's unfinished St. Jerome, Bellini's Piet? , and Caravaggio's Descent from the Crose
Then the following statement: "20 different artists have paintings in the collection." is true, false, or inconclusive?
