Question

volcano forms new pacific island
angela artem

orthern pacific ocean - scientists have discovered a newly-formed island in the northern pacific ocean. the island, named hunga tonga - hunga haapai, is located in an area between hawaii and the samoan islands. scientists believe that an erupting volcano formed the island. the newly-formed island measures roughly two square miles and rises only 100 feet above sea level.

islands form when magma reaches the surface, meets with the earths surface, then merges into the planets crust with rocks and sediment. the erupted lava then cools and hardens to form new islands and landmasses. scientists believe the volcanic activity that has now ceased, was seen erupting over the ocean for hundreds of hours. nevertheless, the lava has only recently risen above the waters surface to form land. scientists think the new island will expand as the volcano continues to erupt.

the theory of plate movement (the earths constant reshuffling of volcanoes, mountains, and landmasses) is caused by heat, as well as an access of magma, pieces of land called plates, move. these plates float on oceans of molten lava under the earths surface.\

which statement best reflects the authors purpose in writing the passage?
a the authors purpose is to inform the reader about how a new pacific island was formed.
b the authors purpose is to entertain readers by making them laugh at the life on a new pacific island.
c the authors purpose is to entertain the reader by discussing possible uses for a new pacific island.
d the authors purpose is to describe the various plant and animal life that can be found on a new pacific island.

Explanation:

The passage is about a new Pacific island formed by a volcano. Option A says the author aims to inform about the island's formation, which matches the content (scientists' discovery, how the island formed, etc.). Option B is wrong as the passage isn't humorous. Option C is wrong as there's no discussion of uses. Option D is wrong as the passage isn't about describing remains. So the best choice is A.

Answer:

A. The author's purpose is to inform the reader about how a new Pacific island was formed.
