Harunia Province has a relatively dry climate and is attracting a fast-growing population that has put increasing demands on its water supply.

Yet now they are asking Harunian authorities to write residential water-use regulations that could reduce their revenues and restrict their future flexibility in supplying water profitably.

Which of the following would, if true, most logically help explain why the water-supply companies are asking the authorities to regulate residential water use?

For most people, the left half of the brain controls linguistic capabilities, but some people have their language centers in the right half.  When a language center of the brain is damaged, for example by a stroke, linguistic capabilities are impaired in some way.  Therefore, people who have suffered a serious stroke on the left side of the brain without suffering any such impairment must have their language centers in the right half.
 
Which of the following is an assumption on which the reasoning in the argument above depends?
