Explanation:

The journal entries record details like arrival at Rio de Janeiro, weather, anchoring, obtaining supplies (greens, beef), getting water and necessities, ship - caulking/repairing, and crew discipline (punishing Seaman John Thurman). These are all necessary information about the voyage. It's not focused on teaching ship - caulking (only a minor part), proving crew was well - fed (just one supply detail), or prompting investors to visit Rio (no such promotional content).

Answer:

to document necessary information about the voyage for its investors
