Insufficent Information in Learning Exercise "The Farm"

[saurami]

There's a lot of gap between the "Introduction" and "Instruction" sections.

In the "Introduction" section, only the first paragraph has information about interfaces. Everything else is about errors. In the code block, DivideFood function receives an interface object and there is no information on this. This makes instructions tough to follow.

Unlike other exercises, multiple tasks are associated with the same function DivideFood. For this exercise, there should be two tasks at most - one for dividing food and the other for the silly nephew custom error.
