All choices for a given question (we have bicameral elections and usually when we have referenda we have multiple at the same time) are on the same piece of paper.

Also they always give you all ballots, I don't recall ever being asked which ones I wanted. Plus at all points you are always in front of multiple people, I believe each candidate / party in an election gets to appoint someone to keep an eye on the proceedings

(Also the original claim about 20/30% seems like abject fantasy to me, unless we take the entirely different meaning of "20-30% vote for a candidate that organized crime is happy with, which is entirely unrelated to electoral interference)
