I want to know the answer to the following question:
In what year was Montini appointed to the Central Preparatory Commission?
All the background I'm provided with is that "The Commission was greatly overshadowed by the insistence of John XXIII to have the Council complete all its work in one single session before Christmas 1962, to the 400th anniversary of the Council of Trent, an insistence which may have also been influenced by the Pope's recent knowledge that he had cancer.". Is that enough to answer the question?
Answer: no
