Digital SAT® Practice Test 1: Reading and Writing Module 1: Question 14 Explanation

The Silver Carp, commonly found in East Asia’s freshwater habitats, has become an unwelcome invader in the waterways of the American Midwest. Its rapid spread can displace native species, disrupting aquatic ecosystems. The Silver Carp, however, is known for jumping out of the water when startled, and this has led researchers to develop underwater sonic tools using this behavior, thereby providing a practical way to locate and control the vast populations of Silver Carp.

Choice C is the best answer. According to the text, the Silver Carp is an invasive species in the American Midwest that can displace native species. In response to the threat, researchers developed sonic tools against them, based on the species’ distinct behavior of jumping out of water when startled. Therefore, it would logically follow that the development of such technology would be used to mitigate the rapid spread of the invading species.

Choice A: The purpose of the development of sonic tools is not described as providing people with entertainment.

Choice B: The text does not indicate that the researchers developed the technology merely to test the behaviors of an invasive species.

Choice D: Separating Silver Carps from human activity is not at all mentioned in the text.
