Take the following as truth: The Galleria Nazionale (on Piazzale Marconi) exhibits more excellent works of Correggio and Parmigianino, and an added prize of the collection, the sketch of a young girl, Testa di Fanciulla, by Leonardo da Vinci.
Then the following statement: "The National Gallery includes a good selection of pieces by Correggio and Parmigianino as well as the highly coveted work by da Vinci, sketch of a young girl." is true, false, or inconclusive?
