Question

water that travel throughout the oceans. currents affect ecosystems. for example, they carry plankton, deepwater creatures, which is vital for the ecosystem. ocean currents also affect water temperatures, climate, tides, and weather events. understanding the shape of the seafloor and any changes to it can provide invaluable early warnings to ships and coastal cities about sea - level increases, tsunamis, and storms. according to the united nations, 40 percent of the world’s population lives within 0 miles of a coast. humanity can benefit from understanding what is going on under the ocean’s surface.
finally, beyond the known benefits, a rich treasure trove of unknown discoveries is waiting on the seafloor. already, studying this unique environment has revolutionized science in important ways. for example, the discovery of ecosystems in thermal vents deep underwater changed how we view life requirements. coastal mapping coordinator ashley chappell at the u.s. national oceanic and atmospheric administration explains, \data is used in coastal ocean science, habitat characterization, wave models, flooding models, wind energy development, all kinds of things.\
humankind already extracts resources such as fish and oil from the ocean. in fact, three billion people eat fish as a main source of food. understanding what else is going on under the sea will help us protect that food
question 7: who is most likely an intended audience of the article?
a. students debating whether they should major in marine biology
b. fishers trying to find new areas of the ocean to fish
c. investors looking for worthwhile ventures to fund
d. boat captains who take tourists on ocean excursions

Explanation:

The article discusses ocean ecosystems, seafloor discoveries, and coastal mapping benefits (e.g., storm warnings, resource protection). Option A involves students considering marine biology, a field directly related to the article’s focus on ocean science and discoveries. Other options (fisheries, investors, boat captains) target narrow, practical uses not central to the article’s scientific and exploratory tone.

Answer:

A. Students debating whether they should major in marine biology
