What the scientists did: Plastics tend to break down, due to heat and sunlight exposure, into small particles known as microplastics. In the past, scientists estimated the size of the Great Pacific Garbage Patch by hopping on a boat and trawling the trash with fine nets — nets originally designed for catching plankton.

Question

Running these nets through the patch, which extends from California to Hawaii, was not only laborious, it failed to catch big things like bottles and buoys. Scientists tried counting these larger items by eye, but they could only do so for small sections of the patch. By extrapolating, they could develop a sense of the Great Pacific Garbage Patch size, but their final estimates — especially for large pieces of trash — varied dramatically.

Three years ago, The Ocean Cleanup foundation opted for a more direct approach. The Netherlands-based organization hired 18 ships to trawl at different spots across the whole patch. But they used 652 nets capable of catching microplastics or larger trash.

Answer 1

The line from the passage that demonstrates a cause/effect text structure is:

“Plastics tend to break down, due to heat and sunlight exposure, into small particles known as microplastics.”

This sentence shows a cause (heat and sunlight exposure) that leads to an effect (the breakdown of plastics into microplastics).
