I want to know the answer to the following question:
Who did Cardinal Giovanni Battista Montini later become?
All the background I'm provided with is that "Cardinal Giovanni Battista Montini, who later became Pope Paul VI, remarked to Giulio Bevilacqua that "this holy old boy doesn't realise what a hornet's nest he's stirring up".". Is that enough to answer the question?
Answer: yes
