Answer:
A timeline is almost exactly how it sounds. It is like the events leading up to the conclusion, and those events are in chronological order. Like maybe i went fishing, and i had the idea of going fishing because some events happened. A timeline of that would be: I was walking by the street and I went inside a market, and I saw some fish. The fish were too expensive so I had the idea to fish for myself. I left the market and went to another store. At that store I bought a fishing rod, fishing bait, and other supplies etc... After all those events I went to fish. A timeline would also be used for a crime investigation, for each suspect a timeline would be built to see if their alibis are valid. Brochures are something you would receive at the beginning of a tour, a paper that can be folded something in something portable, or at least more portable. They might contain information and the history of sites you might be visiting, most of them with pictures too. These are different then timelines because they usually contain more than one event, and they are not long, more like a paragraph or so.
