The question states that there are four differently shaded areas on a given map, with one indicating non-cereal crop production and the other three indicating cereal crop production. The student needs to identify the area that shows non-cereal crop production. Each area is labeled with a number from 1 to 4.

Option 1 suggests that area 1 is the non-cereal crop production. Option 2 suggests the same for area 2, and option 3 suggests this for area 3. Option 4 suggests that area 4 is the non-cereal crop production. The correct answer is option 4, meaning that area 4 is the one that shows non-cereal crop production.

Thus, to understand this, you need to recognize that each option represents a different area, and the one numbered as 4 is the correct answer, hence it represents the non-cereal crop production area on the map.
