Multiple Choice
The class was investigating changes in the water cycle. Students were taking turns collecting water from the sink. What should the students do to conserve water during their investigation?
Get more water than they need.
Turn the water off after each student.
Make the water flow faster.

8
Multiple Choice
How can resource management help achieve long-term food security?
It makes sure that all agricultural land is used only for industrial farming.
It allows the overuse of any resource to meet immediate food needs.
It encourages sustainable farming techniques and protects resources such as soil and water.
It only focuses on increased food production without considering environmental impacts.
9
Multiple Choice
Can resource management prevent food shortages and reduce the risk of malnutrition?
Yes, by ensuring that agricultural resources such as water and soil are used efficiently.
No, because food shortages are caused by overpopulation and are unaffected by resource management.
Yes, by reducing agricultural production to minimize the impact on the environment.
No, resource management has no impact on food security.
10
Multiple Choice
Which of the following is an advantage of effective resource management of energy resources?
increased energy usuage
higher costs for energy resources
decreased accessibility to energy resources
reduced global energy demand
11
Multiple Choice
Which of the following does NOT contribute to water pollution.
farming
watering plants
highly populated areas
industrial waste
12
Multiple Choice
In some areas of Texas, suburbs are growing into areas that were once used for manufacturing. These manufacturers are now making changes to the amount of waste products that are sent into the air. Is is now important to protect air quality because __.
decreasing air pollution can cause more violent thunderstorms.
air pollution changes the wind currents in an area
the amount of energy produced by the Sun increases when there is more air pollution
people's health and ability to be active is impacted by air pollution
13
Multiple Choice
Many coastal areas that are dependent on fishing for their local economies have struggled recently because of overfishing. Scientists have been working with these communities to reestablish the fish populations.
Which of the following would NOT be a recommendation of the scientists to help the local communities?
