4. フードバンク等の革新的技術による食品ロス削減の可能性と効果について

Explanation: When analyzing main argument questions on the AP Japanese exam, you need to identify the central thesis that encompasses the entire passage, not just individual points or examples mentioned within it. This passage presents a clear contrast structure: it begins with Japan's traditional "mottainai" (waste not) spirit in food culture, then shifts to discuss the modern food waste problem, explores the underlying causes of this contradiction, and concludes by noting that while new solutions exist, fundamental consciousness change is needed. The author's main point is highlighting this tension between traditional values and contemporary reality, along with the challenge of bridging that gap. Choice A focuses too narrowly on economic development and value loss, missing the specific food waste issue and solution-seeking aspects that dominate the passage. Choice B emphasizes only the distribution system efficiency problem, which is mentioned as just one contributing factor among several, not the main argument. Choice D concentrates solely on technological solutions like food banks, but these appear only as examples in the final section, not as the passage's central concern. Choice C correctly captures the passage's full scope: the traditional "mottainai" concept, its contrast with current food waste problems, and the challenges involved in addressing this issue. This encompasses both the cultural-historical context and the contemporary problem-solving discussion that frames the entire text. For main idea questions, look for answer choices that reflect the passage's complete argumentative arc rather than focusing on specific examples or supporting details mentioned along the way.

Question 20

1. AI技術の進歩による雇用市場の完全な変革と労働者の大量失業危機について
2. 人間固有の創造性と感情機能の優位性と AI技術の根本的限界について
3. 新興技術職の創出によるデジタル経済社会の発展可能性について
4. AI時代における人間とAIの協働関係構築と社会適応の必要性について (correct answer)

Explanation: When you encounter a reading comprehension question asking for the "basic argument" (基本的な主張), you need to identify the passage's central thesis rather than focusing on specific details or supporting points. This passage presents a balanced view of AI's impact on society. The author acknowledges that AI will displace some jobs while creating others, but the key message emerges in the final portion: "重要なことは、AIと人間が対立するのではなく、それぞれの特性を活かして協働する社会を構築することです" (The important thing is not for AI and humans to oppose each other, but to build a society where they collaborate by utilizing their respective characteristics). The passage then emphasizes that achieving this requires educational reform, job training, and social adaptation - making D the correct answer. Option A is too narrow and pessimistic. While the passage mentions job displacement, it doesn't focus on "complete transformation" or "mass unemployment crisis." Option B misrepresents the passage's tone - it doesn't argue for human superiority or AI's "fundamental limitations," but rather complementary roles. Option C captures only a minor point about new tech jobs, missing the broader collaboration theme that dominates the conclusion. The wrong answers represent common traps: focusing on alarming details (A), oversimplifying the human-vs-AI dynamic (B), or fixating on a supporting example rather than the main argument (C). Strategy tip: In passages about technology and society, look for synthesis statements that propose solutions or balanced approaches - these often contain the main argument rather than the problem descriptions that appear earlier.
