I want to know the answer to the following question:
What do Torrent files NOT contain?
All the background I'm provided with is that "Some torrent indexing and search sites, such as The Pirate Bay, now encourage the use of magnet links, instead of direct links to torrent files, creating another layer of indirection; using such links, torrent files are obtained from other peers, rather than from a particular website.". Is that enough to answer the question?
Answer: no
