French divers recently found a large cave along the coast of the Mediterranean Sea. The cave is accessible only through an underwater tunnel. The interior of the cave is completely filled with seawater and contains numerous large stalagmites, which are stony pillars that form when drops of water fall repeatedly on a single spot on a cave floor, leaving behind mineral deposits that accumulate over time.
The information above most strongly supports which one of the following?
(A) The Mediterranean Sea
was at a higher level in the past than it is now. - WRONG. The formation of stalagmite would not have been possible.
(B) The water level within the cave is higher now than it once was. - CORRECT. If not then accumulation of mineral deposits is questionable.
(C) The
French divers were the first people who knew that the tunnel leading to the cave existed. - WRONG. Totally not inferable.
(D) There was once
an entrance to the cave besides the underwater tunnel. - WRONG. Not necessarily as there could well be many and none.
(E) Seawater in the Mediterranean
has a lower mineral content now than it had when the stalagmites were being formed. - WRONG. It is possible either way.
Answer B.
