問 1
What is the main idea of the passage?
- The bicycle was always a fast and dangerous racing machine.
- The bicycle was used only by a few very rich people.
- The simple bicycle changed society and gave people new freedom of movement.
- The bicycle had almost no effect on society at all.
changed society in ways few expected ... a freedom of movement they had never known
予想外の形で社会を変え、未知の移動の自由を与えた
記事の主旨は「単純な発明の自転車が予想外に社会を変え、人々に新たな移動の自由(特に女性の自立)を与え、今も重要」。
「The simple bicycle changed society and gave people new freedom of movement.」
正解第1段落 "this simple invention ... changed society in ways that few people expected ... gave ordinary people a freedom of movement they had never known" が主旨。記事は初期の姿 → 社会的影響 → 現代と展開。powered by ~ = 「〜で動く」、freedom of movement = 「移動の自由」。
「The bicycle spread widely but had almost no effect on society at all.」
= 社会にほぼ無影響 ━ 本文 "changed society in ways that few people expected" と矛盾。
「The bicycle was always a fast, dangerous racing machine used only for sport.」
= 常に速く危険な競走用機械 ━ 本文 "Cheap, clean, and easy to use" "almost anyone could enjoy" と矛盾。
「The bicycle was used only by a few very rich people and never spread.」
= ごく一部の富裕層だけ ━ 本文 "ordinary people" と矛盾。
| パターン | 意味 | 例 |
|---|---|---|
| powered by ~ | 〜で動く | powered only by human muscle |
| changed society | 社会を変えた | changed society |
| freedom of movement | 移動の自由 | a freedom of movement |
| stop to think about ~ | 立ち止まって〜を考える | stop to think about it |
| easy to use | 使いやすい | easy to use |
The bicycle changed society.
自転車は社会を変えた。

それは人々に移動の自由を与えた。
It is powered only by muscle.

主旨設問の鉄則 ―― "changed society in ways that few expected ... freedom of movement" が主旨。誤答は本文と矛盾 (無影響 / 競走用 / 富裕層だけ) で誘導。社会変化 + 移動の自由を含む選択肢が正解。
