In the 1920’s, tires were sunk along the Florida coast to create artificial barrier reefs. Because many of the tires are constantly in motion, no marine life has been attracted to this artificial habitat. Now marine biologists are in the process of removing the tires from the ocean floor. Which statement best describes the reason the tires are being removed?
Scientists are making space for natural reefs to develop.
Marine life has evolved and is no longer attracted to the material.
New observations have led scientists to reconsider their original hypothesis.
The scientists formed their hypothesis after the investigation had taken place.
