Problem 2

Explanation

Let's analyze the given premises:

1. All residents of Nelayan Village are fish farmers.
2. Residents who have cultivation land $\rightarrow$ make organic feed.
3. Residents who do not have cultivation land $\rightarrow$ make inorganic feed.

Every resident must fall into one of two conditions: either they have land or they do not have land.

• If a resident has land, then they make organic feed.
• If a resident does not have land, then they make inorganic feed.

Since all residents belong to one of these two groups, it can be concluded that all residents must perform one of these two activities: making organic feed or making inorganic feed.

Therefore, the most correct conclusion is All residents of Nelayan Village make organic fish feed or inorganic fish feed.
