Question

1. ordinary soap bubbles usually exist for a minute or less before popping due to either a rupture forced by gravity - induced drainage or the evaporation of the liquid from which the bubble is composed. but physicist aymeric roux and colleagues discovered ways to mitigate these factors, resulting in bubbles that can last for a year or more. for example, glycerol tends to adhere to water molecules, so a bubble with a shell that contains both water and glycerol is able to draw additional water molecules from the surrounding air and thereby compensate for evaporation. which choice best states the purpose of the underlined portion in the text as a whole? it describes the effects of a process devised by researchers that increases the longevity of an object discussed in the text. it details the circumstances that prompted the research discussed in the text. it presents a reason why the phenomenon discussed in the text that the researchers wanted to avoid will inevitably occur. it mentions a method discussed in the text that researchers intend to test in future experiments.

Explanation:

The under - lined part shows how glycerol helps increase soap bubble longevity. It describes effects of a process by researchers.

Answer:

It describes the effects of a process devised by researchers that increases the longevity of an object discussed in the text.
