Use the passage to answer the question

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.

Which is the most effective way to separate the two sections at the blank line?

A. by including an infographic of university studies on water pollution
B. by using captions to summarize the article
C. by using bullets to reorganize the first section
D. by inserting a heading about the topic of the second section

D. by inserting a heading about the topic of the second section

D. by inserting a heading about the topic of the second section

To determine the most effective way to separate the two sections at the blank line, we need to analyze the passage and consider which option would provide the clearest and most logical division.

A. Including an infographic of university studies on water pollution might be informative, but it doesn't necessarily address the need to separate the sections.

B. Using captions to summarize the article could be helpful in providing a concise overview, but it may not effectively separate the sections.

C. Using bullets to reorganize the first section might aid in organizing the information, but it may not clearly separate the two sections.

D. Inserting a heading about the topic of the second section would likely be the most effective way to separate the sections. By including a clear heading that indicates the change in focus from the shade balls to the potential impact on water consumption in other parts of the world, the reader would immediately recognize the transition between the two topics.

Therefore, the most effective way to separate the two sections at the blank line would be to choose option D: by inserting a heading about the topic of the second section.
