Answer:
- An encyclopedia entry on the different countries that produce coffee.
- Official records of coffee production data in different countries .
- A research study on the different types of coffee found around the world.
Step-by-step explanation:
If the goal is to write an essay about the global production of coffee, then it is logical to search for data regarding coffee production in that scale. Production records of coffee in many countries would be essential to include.
However, aspects such as benefits of consuming coffee and coffee-related recipes have nothing to do with production, and therefore must not be included.
