Question

[107]. Read the following passage carefully:

Passage: "Every morning, a boy named Naman walked to the bank of the great river with a notebook. He was not fishing. He was counting river dolphins. The dolphins rose briefly to breathe, showed their grey backs, and vanished again. Naman recorded how many he saw and at what time. Over months, his notes showed a worrying pattern: on days when boats with loud engines passed, fewer dolphins appeared. He shared his notebook with a local teacher, who helped him write a short report. The report did not demand that boats stop. It suggested quiet zones near the dolphin feeding areas and slower speeds at dawn. When boatmen read the report, many agreed, because they too had noticed that the river was changing. Naman learned that careful observation, honestly recorded, can speak more powerfully than loud complaints." What pattern did Naman's notes show?

1.
Fewer dolphins appeared on days when loud-engine boats passed.
2.
Dolphins appeared only at night.
3.
Dolphins never appeared near feeding areas.
4.
Boatmen always refused to listen.
