Question

1. read the text.
2. beavers in the wild build dams of sticks and dirt across streams and brooks, blocking the flow of water and forming ponds and wetlands. this behavior can cause conflicts with people when beaver dams flood roadways and property. if the dam is destroyed, the beavers will rebuild, because when they hear running water, their instinct is to dam it. engineers cleverly resolved this issue by designing a special pipe that is inserted through the middle of a beaver dam. the pipes end is located away from the dam and fenced off, so beavers cant block it. water flows through the pipe, both preserving the beavers pond habitat and protecting peoples property.
3. which organizational structure does this text primarily use?
4. problem-solution

compare-contrast
sequential

Explanation:

The text first presents the problem: beaver dams flood roadways/property, and destroying dams doesn't work as beavers rebuild. Then it introduces the engineered pipe solution that protects both beavers and human property, which follows a problem-solution structure. Compare-contrast would involve highlighting differences/similarities between two subjects, and sequential would focus on a time-based order of events, neither of which match the text.

Answer:

problem-solution
