Read the paragraph.

If added at the end, which sentence would complete the paragraph by connecting back to the topic?

The average American household spends over $500 a year on water.
With a little effort, people could easily protect this resource by conserving it.
Another resource that people should think about protecting is energy.
Since seventy percent of the Earth is covered by water, there is a lot of water around.

Answer 1

"With a little effort, people could easily protect this resource by conserving it."

This directly connects back to the topic (water) and follows naturally from noting household water use.
