セクション11：発表と協力：活動記事の情報・推論

A student project led by Yuna began at the music hall. Its purpose was to bring different ages together. Members worked with songs, and the first practical outcome was a concert program. Yuna brought a song sheet, but the organizer emphasized that equipment was only one part of a successful project.

During preparation, the loudest members made most of the decisions. The group tried collecting written suggestions before discussion. This brought forward ideas from members who rarely spoke. Some suggestions conflicted, so the group still needed to discuss priorities. The new method did not remove disagreement; it made more people's views available before a decision was made.

問11（5点）

  1. To bring different ages together.
  2. To replace every activity in the town.
  3. To advertise luxury products.
  4. To prove that experts were unnecessary.

問12（5点）

Which outcome is mentioned in the passage?

  1. a concert program
  2. a travel ticket
  3. a weather forecast
  4. a national law

問13（5点）

What was the purpose of collecting written suggestions?

  1. To cancel the activity without discussion.
  2. To eliminate every disagreement.
  3. To give the loudest members more authority.
  4. To include views that were rarely heard in discussion.

問14（5点）

What remained necessary after collecting suggestions?

  1. Only the appearance of the final product mattered.
  2. The team should never collect further evidence.
  3. Discussing conflicting ideas and priorities.
  4. The original approach needed no changes.

セクション12：庭づくり：活動記事の情報・推論

A student project led by Aki began at the school garden. Its purpose was to help butterflies. Members worked with flowers, and the first practical outcome was a flower bed. Aki brought a watering can, but the organizer emphasized that equipment was only one part of a successful project.

The group compared two plots. One received regular care, while the other was checked only occasionally. More plants survived in the first plot. However, the plots also received different amounts of sunlight. The group therefore avoided claiming that the care schedule alone explained the difference. For the next comparison, they planned to use plots with similar light conditions.

問15（5点）

What was the main purpose of the project?

  1. To replace every activity in the town.
  2. To help butterflies.

問17（5点）

Why was the first comparison inconclusive?

  1. No plants survived in either plot.
  2. The plots differed in sunlight as well as care.
  3. Both plots received exactly the same treatment.
  4. The group had no interest in plants.

問18（5点）

What would improve the next comparison?

  1. Keeping light conditions similar while comparing care schedules.
  2. The original approach needed no changes.
  3. The team should never collect further evidence.
  4. Only the appearance of the final product mattered.
