Sample Summarize Written Text Task on Water Desalination Technology Advancements

Task Prompt:

Water scarcity has become a pressing challenge globally, with rising populations and climate change exacerbating the problem. One solution gaining traction is desalination, the process of removing salt and other impurities from seawater to produce fresh water. Recent innovations in desalination technologies have significantly improved the efficiency and sustainability of this process. For example, reverse osmosis, a common desalination method, has been enhanced by the introduction of more energy-efficient membranes and advanced filtration systems. Furthermore, researchers are looking into renewable energy sources, such as solar panels, to power desalination plants, potentially reducing their environmental impact. Despite these advancements, challenges like high operational costs and concerns over brine disposal remain significant obstacles to large-scale adoption.

Summarize the text in one sentence (5–75 words):


Model Answers
