Balls' May Not Save
Water"
by Amanda Grennell
In 2015, the world watched as a video of 96 million
"shade balls" getting dumped into the Los Angeles Reservoir went viral. The purpose of the balls: to improve water quality and save water.
But a new study raises an interesting question:
Could saving water in the Los Angeles Reservoir come at the cost of consuming water in other parts of world?
At the time, Californians faced a record-setting drought, and conserving water was on everyone's minds. Mandatory water restrictions led to brown lawns and shorter showers.
The Los Angeles Department of Water and Power said the shade balls could keep contaminants out of the water and reduce the evaporation of the reservoir by 85 to 90 percent during a drought. The officials said the annual savings could amount to up to 300 million gallons of water, enough to supply drinking water to 8,100 people.
Use the passage to answer the question.
Which is the most effective way to separate the two sections at the blank line?
(1 point)
by inserting a heading about the topic of the second section
by using captions to summarize the article
by using bullets to reorganize the first section
by including an infographic of university studies on water pollution

The most effective way to separate the two sections at the blank line is:
by inserting a heading about the topic of the second section
This option clearly delineates the two parts of the passage, guiding the reader on the transition from the initial topic regarding shade balls to the subsequent discussion about potential implications on water consumption elsewhere.
