Using advanced sonar mapping technology, Dr. Johan Mescher and his team measured the acoustic patterns of deep-sea thermal vents in the Pacific Ocean. Different geological formations create distinct sonar signatures, and the acoustic data revealed the presence of previously unknown underground magma chambers. This discovery not only provides the first concrete evidence of an extensive magma network beneath this region of the ocean floor but also demonstrates the tremendous potential of high-resolution sonar mapping for future marine geology research.

Which choice best describes the overall structure of the text?

A. It discusses a method used by some researchers, then states why an alternative method is superior to it.

B. It describes how researchers made a scientific discovery, then explains the importance of that discovery.

C. It outlines the steps taken in a scientific study, then presents a hypothesis based on that study.

D. It examines how a group of scientists reached a conclusion, then shows how other scientists have challenged that conclusion.
