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.

Summary
French divers found a cave that is only accessible through an underwater tunnel. The cave was nearly filled with water and contains numerous stalagmites. Stalagmites are stony pillars that are form when drops of water repeatedly fall in the same spot on a cave floor.

Strongly Supported Conclusions
The cave was not always filled with water (because the stalagmites had to form from water dripping on the ground)

A
The Mediterranean Sea was at a higher level in the past than it is now.
This is too strong to support. While it is possible that the water in the Mediterranean Sea was lower in the past, this is too large of an assumption to make. All we know is that there is more water in the cave now.
B
The water level within the cave is higher now than it once was.
This is strongly supported. The cave is now entirely filled with water. Stalagmites only form when drops of water repeatedly land on a single spot. The water must have risen since the stalagmites were formed.
C
The French divers were the first people who knew that the tunnel leading to the cave existed.
There is no evidence for this anywhere in the stimulus. We are not told who discovered the cave first.
D
There was once an entrance to the cave besides the underwater tunnel.
There is no support for this anywhere in the stimulus. Nothing points to there being another entrance.
E
Seawater in the Mediterranean has a lower mineral content now than it had when the stalagmites were being formed.
This is far too strong of a statement to support. The mineral content of the water does not play any major role in these statements. You need to make a lot of assumptions to make this work
