While researching a topic, a student has taken the following notes:
The student wants to summarize the kelp highway hypothesis. Which choice most effectively uses relevant information from the notes to accomplish this goal?
Pacific Ocean islands and coastlines likely contained “a rich mix of marine, estuarine, riverine, and terrestrial resources” such as seaweeds, fish, and birds, according to researchers.
One argument about how humans first arrived in the Americas is the kelp highway hypothesis proposed by Jon Erlandson and colleagues.
Humans may have first arrived in the Americas by sea, traveling between Pacific Ocean islands and coastlines and subsisting on a variety of resources.
As glaciers melted and sea levels rose, many Pacific Ocean islands and coastal zones were submerged.
Choice C is the best answer. This choice summarizes the main idea of the kelp highway hypothesis, providing a high-level overview of how the hypothesis explains human migration to the Americas.
Choice A is incorrect. This choice describes one aspect of the proposed scenario but doesn’t discuss human migration, which is the main focus of the kelp highway hypothesis. Choice B is incorrect. This choice introduces the kelp highway hypothesis but doesn’t explain what it entails. Choice D is incorrect. This choice describes one element of the proposed scenario but doesn’t discuss human migration, which is the main focus of the kelp highway hypothesis.
