Follow these guidelines when writing on the essay:
First, caption the essay that you are writing about.
Begin with an overview of water shorter during summer.
Discuss in detail the effects that such shortages cause.
Provide suggestions on how the water shortages can be curbed.
Conclude with a restatement of the main ideas.
The essay is an expository essay because it requires you to provide details about the topic provided. This requires that proper research is done. Highlight the effects of water shortages during summer.
Finally, provide ideas on how such situations can be managed.
I would say that "constant cry" and "Chesterton's cat" are the obvious ones. However "echoed in our ears" is a pretty subtle one that you can definitely make a solid argument for.
