Question:

Read the passage and answer the question. In 2023, researchers sampling rainfall in the Pyrenees found something they had not expected: tiny fragments of plastic in almost every sample, including those collected far from any town or road. The particles, most smaller than a grain of sand, are thought to travel on wind currents from distant cities, laundries and highways before falling back to earth with the rain. Laboratory analysis showed the fragments matched common packaging films and synthetic fibres from clothing. Ecologists warn that alpine lakes and the streams feeding them may be accumulating these particles year after year, with unknown effects on the insects and fish at the base of the mountain food web. Because high-altitude regions were long assumed to be untouched by urban waste, the findings have forced a rethink of how far plastic pollution can spread. According to the passage, the discovery of microplastics in mountain rainfall matters chiefly because it

proves that mountain air is cleaner than city air

shows that plastic production has recently declined worldwide

indicates that plastic pollution has reached even pristine environments

explains the chemical cause of acid rain in the Pyrenees

Correct Answer: indicates that plastic pollution has reached even pristine environments

The passage stresses that high-altitude regions were assumed untouched by urban waste, so finding plastic in their rain shows pollution has spread even to pristine environments.
