  托福阅读句子插入题:The Geologic History

  【Paragraph 2】■Another task for the Glomar Challenger’s scientists was to try to determine the origin of the  domelike masses buried deep beneath the Mediterranean seafloor. ■These structures had been detected years earlier by echo-sounding instruments, but they had never been penetrated in the course of drilling. ■Were they salt domes such as are common along the United States Gulf Coast, and if so, why should there have been so much solid crystalline salt beneath the floor of the Mediterranean? ■(The Geologic History of the Mediterranean)
