The Rienzi, a passenger ship, sank as a result of a hole in its hull, possibly caused by sabotage. Normally, when a holed ship sinks as rapidly as the Rienzi did, water does not enter the ship quickly enough for the ship to be fully flooded when it reaches the ocean floor. Full flooding can be achieved, however, by sabotage. Any ship that sinks deep into the ocean when not fully flooded will implode. Deep-sea photographs, taken of the sunken Rienzi where it rests on the ocean floor, reveal that the Rienzi did not implode.

Summary
The Rienzi sank because it had a hole. It descended rapidly. Usually, ships that sink this fast don’t fully flood by the time they reach the ocean floor, which makes them implode. The Rienzi did not implode. Sabotage can cause a ship to flood fully.

Notable Valid Inferences
The Rienzi must have fully flooded by the time it was deep in the ocean—we know this because if it hadn’t flooded fully, it would have imploded. We cannot conclude what caused the full flooding, but we can infer that it was either sabotage or that the Rienzi filled with water faster than normal.

A
The Rienzi was so constructed as to reduce the risk of sinking by impact.
This could be false. The stimulus does not offer any information about how the Rienzi was constructed.
B
If the Rienzi became fully flooded, it did so only after it reached the ocean floor.
This must be false. We know the Rienzi must have fully flooded when it reached the ocean floor or it would have imploded.
C
If the Rienzi was not sunk by sabotage, water flooded into it unusually fast.
This must be true. We know the Rienzi fully flooded by the time it reached the ocean floor—this means it was either sabotaged to allow for full flooding or water entered the ship faster than normal.
D
If the Rienzi had sunk more slowly, it would have imploded.
This could be false. We don’t know if the rate at which the Rienzi sunk caused the ship not to flood fully, and whether changing the rate would affect this outcome.
E
The Rienzi was so strongly constructed as to resist imploding under deep-sea pressure.
This could be false. The stimulus does not offer any information about how the Rienzi was constructed.
