Logging companies cut trees in a forest and send the trees to lumber mills far from the forest. The mills make boards that are used for construction. Some logging companies do not plant tree seedlings after cutting trees.
Not planting tree seedlings might affect people who need boards in the future because
- the price of boards will increase
- the price of boards will decrease
- there will be more boards available
- there will be more trees for logging

Bald eagles are found in and near desert, mountain, freshwater, and marine environments throughout the United States. Bald eagles build huge nests that are usually in treetops, near areas of water. The main food source for bald eagles is fish, but the birds sometimes eat other small animals. In
1967, the bald eagle was listed as an endangered species by the Environmental Protection Agency. The widespread use of DDT was responsible for the decline in the number of eagles. DDT, a chemical commonly used to control mosquitoes, caused thinning of the eagle egg shells.

Which statement is the most likely reason for the large difference in the number of breeding pairs in Maryland and Nevada?
- There are fewer trees in Maryland.

A teacher asks her students the following question: How does the air pressure inside a soccer ball affect the distance the soccer ball travels after the ball is kicked?
Which statement below is the best hypothesis for this investigation?
- If a soccer ball is large, then the soccer ball will travel a farther distance than a small soccer ball.
- If a soccer ball has a high internal air pressure, then the ball will travel a farther distance than a soccer ball with less internal air
pressure.
- If a soccer ball travels a distance of 15 meters, then the ball is traveling faster than a soccer ball that travels a distance of 20
meters.
- If a soccer ball has 0.5 atmospheres of internal pressure, then the ball will travel slower than a ball with 0.8 atmospheres of internal
pressure.
