Answer:
For any real experiment there must be at least five things: an independent variable, a dependent variable, control variables, and two groups often one experimental and one control.
Carlos hypothesis is that by fixing leaks their water consumption would be lower. As such his dependent variable is the water consumption and his independent variable (the one he is manipulating) is the amount of leaks in the house.
In order to make this an experiment Carlos needs to first make sure there is an actual decrease in the water consumed, and second he needs to make sure it's due to the fixed leaks. So to do this Carlos should measure their water consumption during a period of time before fixing the leaks and then measure the water use for the same period of time after fixing. The harder part is making sure that no other variables can interfere, these are called control variables. For example if before fixing the leaks Carlos had a huge party and had to wash a lot of dishes any decrease in water could be due to this. Therefore he would need to either make sure water is used for the same things in the same amounts during these two periods or track any increases due to specific events happening in only one of the periods.

Explanation:
Hunger is regulated by the hypothalamus, which is a region located in the brain. Due to this, people with injuries in this zone might experience issues regulating their appetites such as lack of satisfaction after eating or lack of impulse to eat (hunger). Thus, if a patient does not feel hungry and experienced a brain injury, this is likely related to the hypothalamus. On the other hand, the thalamus, which is a different zone in the brain located above the hypothalamus regulates sensory impulses and movements but it is not related to appetite or hunger.
