The small remaining task
Read the entire original fictional scene: 「発表会が終わると、みんなは先に教室を出ていった。私は、机の上に残った色紙を一枚ずつ重ねた。『もう帰ろう』と友人が戸口から言った。私は『うん』と答えたが、最後の一枚だけは、しばらく手に持っていた。友人は何も言わず、隣の机の椅子を静かに戻した。」 No graduation, illness or quarrel is stated. The task concerns what can reasonably be inferred from actions at the end of the event. Compare a modest interpretation supported by the delay with an elaborate claim about an unstated background. Pay attention to the friend's choice to remain and quietly help rather than immediately treating silence as anger or indifference. Distinguish what each person says from what each person actually does.
1. What supports an inference of reluctance to leave the event behind?
Read the worked answer
The narrator answers that they will go but continues holding the final sheet. That pause after the event supports lingering attachment or reluctance to finish.
2. What does the friend's response suggest, and what remains unknown?
Read the worked answer
Quietly staying to return a chair suggests patient company or support. The passage does not establish a specific hidden promise, conflict or future separation.
