Dear readers
Find below the solution to the case posted last Friday. I hope you can enjoy it. See you again this Friday, with the first section of the last example of this saga: an agricultural product for Central America, in the context of food security. Food security means having, “at all times, both physical and economic access to sufficient food to meet dietary needs for a productive and healthy life. A family is food secure when its members do not live in hunger or fear of hunger”.

See you this coming Friday, and good night. Thank you for waiting for this solution that can be applied in any country on Earth.
