Question

Would you believe that many of the Caribbean islands were once volcanoes? It’s true. There is a large chain of volcanoes that lies beneath the Caribbean Sea. Many of the islands we see today, including Jamaica and Cuba, were formed on top of volcanoes.
Over many years, the volcanoes were submerged beneath the sea. Limestone began to develop over the igneous and metamorphic rock that was already there. To this day in Jamaica, there are places where the limestone on the island is thousands of feet thick.

B.
Limestone on other islands in the Caribbean Sea is also thousands of feet thick and miles long.

Some Caribbean islands were formed as a result of volcanoes being submerged underwater.
D.
Jamaica, Cuba, and Puerto Rico formed as a result of volcanic eruptions in the Caribbean Sea.

Answer 1

C. The passage states that many Caribbean islands (including Jamaica and Cuba) were formed on top of volcanoes and that these volcanoes were later submerged beneath the sea, so it supports the conclusion that some islands were formed as a result of submerged volcanoes.
