問 1
What is the main idea of the passage?
- Early farmers enjoyed healthier and longer lives than the foragers who came before them.
- The Neolithic Revolution occurred simultaneously across every region of the world.
- The shift to farming, though it spread, was a mixed bargain that often worsened individual welfare while empowering societies as a whole.
- Agriculture failed to spread because hunting and gathering proved more reliable.
a slow, irreversible bargain—one that traded the comfort of the individual for the sheer expansive power of the group
農耕への移行は個人の幸福を犠牲に集団の拡張力を得た『取引』だったという論旨。
「The shift to farming, though it spread, was a mixed bargain that often worsened individual welfare while empowering societies as a whole.」
正解本文は (1) 農耕は文明への前進とされる→ (2) しかし骨の証拠は初期農民が foragers より不健康だったと示す→ (3) それでも人口算術と貯蔵可能な余剰により広まり国家を生んだ、という構成。最終段で『個人の快適さを集団の拡張力と交換した取引』と結論するので、『個人の福祉を悪化させつつ社会全体を強化した取引』が主旨。
「The earliest farmers everywhere enjoyed considerably healthier and longer lives than the foragers who had come before them.」
= 初期農民の方が健康で長寿だった ━ 第2段は逆に農民が shorter で nutritional deficiencies に陥ったと述べており正反対。
「Agriculture failed to spread」
= 農耕は広まらなかった ━ 本文は farming spread and ultimately prevail と明言しており事実と矛盾。
「The Neolithic Revolution occurred entirely simultaneously across every single region of the world at exactly the same time.」
= 全地域で同時に起きた ━ 本文は in a handful of regions と限定し、slow と形容しており『同時に全地域』は言い過ぎ。
| パターン | 意味 | 例 |
|---|---|---|
| make a leap toward ~ | ~へ飛躍する | humanity's first great leap toward civilisation |
| the deeper one digs ... | 掘り下げるほど~ | the deeper one digs, the more ambiguous it becomes |
| trade A for B | AをBと引き換えにする | traded comfort for power |
| lock ~ into a cycle | ~を循環に固定する | locking societies into a cycle |
| give rise to ~ | ~を生じさせる | giving rise to hierarchy |
The transition was less a triumph than a bargain.
その移行は勝利というより取引だった。
The deeper you dig, the more ambiguous the story becomes.
掘り下げるほど話は曖昧になる。
They traded comfort for power.
彼らは快適さを力と引き換えにした。
主旨設問は最終段の比喩 (bargain) と対比構造 (individual ⇔ group) を押さえると速い。極端語 (every / never / fully) を含む肢は外れやすい。
