Question

[120]. Read the following passage carefully and answer the question.

Passage: Himalayan glaciers are slow rivers of ice that store water in winter and release it in summer, feeding great rivers on which millions depend for farming, drinking water and power. A glacier moves only a few metres a year, yet over centuries it carves valleys and carries rocks far from their source. Today many Himalayan glaciers are retreating: their fronts pull back, meltwater lakes grow behind fragile ice dams, and the timing of river flow changes. The causes are complex, involving warming air, dust on ice and changing snowfall. The consequences, however, are practical and immediate for farmers who plan sowing by river flow. Understanding glaciers is therefore not only a matter of science but of food and livelihood. In the context of the passage, the word 'retreating' most nearly means:

1.
a single example of a plant or animal collected for study
2.
a book or document written by hand before printing
3.
a group of travelling performers
4.
moving back, becoming smaller over time
