Okay, I need to create a Wikipedia-style document about apple cultivation under the categories of Economics, Agriculture, and Fruit Cultivation. Let me start by understanding the user's requirements.

First, the structure: H1 for the title, an overview section, several sections with H2 and H3 headings, and maybe references or related documents. The content needs to be accurate, objective, detailed, easy to read, and use technical terms with explanations. Also, markdown formatting with proper hierarchy, lists, tables, code blocks if needed, and at least 800 characters.

Starting with the title: "사과" as specified. Then an overview section introducing apples in agriculture. Next sections could be about cultivation methods, varieties, economic aspects, challenges, etc. Each of these can have sub-sections. For example, under cultivation methods, I can talk about climate requirements, soil types, planting techniques, and harvesting.

I should include information on different apple varieties like Red Delicious, Gala, Fuji, etc., their characteristics. Economic impact: global production stats, major producers, market trends. Challenges might involve pests, diseases, climate change effects. Maybe a section on sustainable practices or future trends.

Need to ensure technical terms are explained. For example, "chilling hours" should be defined. Also, check for accuracy in data like production numbers from FAO or other sources. Use tables for variety characteristics or production statistics if possible. Avoid markdown code blocks unless there's specific tech content, which might not be here.

Check the length: 800 characters is about 150-200 words. The user probably meant 800 characters in total? Wait, no, the instruction says "최소 800자 이상의 충분한 내용" which translates to at least 800 characters. But that's very short for a Wikipedia article. Maybe it's a typo and they mean 800 words? But I'll proceed as per the given instructions.

Wait, in Korean, "자" is a character, so 800 characters would be around 400-500 words. However, considering the user might have meant 800 words, but since they specified 800자, I need to make sure the content meets that. But given the example response provided earlier by the assistant was longer, maybe it's a mistake and should be 800 words. However, I'll follow the exact instruction.

But regardless, I'll structure the document properly with H1, sections, subsections, etc., ensuring all points are covered. Use bullet points for lists, tables where applicable. Make sure each section is informative and flows logically.
