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 of the Rienzi where it rests on the ocean floor, reveal that it did not implode.
Which one of the following must be true on the basis of the information above?
(A) The Rienzi was so constructed as to reduce the risk of sinking by impact.
(B) If the Rienzi became fully flooded, it did so only after it reached the ocean floor.
(C) If the Rienzi was not sunk by sabotage, water flooded into it unusually fast.
(D) If the Rienzi had sunk more slowly it would have imploded.
(E) The Rienzi was so strongly constructed as to resist imploding under deep-sea pressure.

Deep-sea photographs of the Rienzi where it rests on the ocean floor, reveal that it did not implode.
Which one of the following must be true on the basis of the information above?
This is an Inference question, and the correct answer will be the choice that is proven true by the statements in the passage.
(A) The Rienzi was so constructed as to reduce the risk of sinking by impact.
The passage says nothing about how the Rienzi was constructed and does not indicate anything about the relative risk of the Rienzi sinking by impact.
The passage does say that the sinking was "possibly caused by sabotage." At the same time, that information does not mean that the sinking was not caused by an impact or that the Rienzi was at low risk of sinking by impact. After all, the sinking could have been caused by sabotage even if the Rienzi's sinking by impact was high.
Eliminate.
(B) If the Rienzi became fully flooded, it did so only after it reached the ocean floor.
If anything, this choice is contrary to what the passage says.
If, as the passage says, "Any ship that sinks deep into the ocean when not fully flooded will implode," then if the Rienzi had become fully flooded only after it reached the ocean floor, it would have imploded. After all, it would have been deep in the ocean before it was fully flooded.
However, the passage indicates that it did not implode.
So, what the passage says implies that the Rienzi became fully flooded before, rather than after, it reached the ocean floor.
Eliminate.
(C) If the Rienzi was not sunk by sabotage, water flooded into it unusually fast.
This choice is interesting.
The passage says, "Any ship that sinks deep into the ocean when not fully flooded will implode. Deep-sea photographs of the Rienzi where it rests on the ocean floor, reveal that it did not implode." That information indicates that the Rienzi must have been fully flooded.
The passage also says, "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." This fact and the fact that the Rienzi was fully flooded combine to indicate that water flooded into the Rienzi unusually fast. After all, if what happens "normally" didn't happen, then what happened was unusual. In this case, what was unusual was the rate at which water must have entered the ship. It must have entered "unusually fast."
Finally, we see that the passage says, "Full flooding can be achieved, however, by sabotage." That information indicates that sabotage can cause water to enter faster than normal because water must enter faster than normal for a ship to be fully flooded.
So, we see that the Rienzi flooded unusually fast as long as it wasn't sunk by sabotage since, if it was sunk by sabotage, then fast flooding was not unusual.
Thus, this choice is fully supported by the passage.
Keep.
(D) If the Rienzi had sunk more slowly it would have imploded.
This choice is contrary to what the passage says.
After all, the passage says, "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." Given that information, we see that, if the Rienzi had sunk more slowly, water would have had more time to enter and fully flood the ship, thus preventing it from imploding, rather than causing it to implode.
Eliminate.
(E) The Rienzi was so strongly constructed as to resist imploding under deep-sea pressure.
The passage does indicate that the Rienzi did not implode.
However, it does not say or imply anything about how "strongly constructed" the Rienzi was. Rather, the passage suggests that full flooding of the Rienzi caused by sabotage may have prevented it from imploding.
Eliminate.

Which one of the following must be true on the basis of the information above?
Clearly C.. Two indicators - Rienzi sank rapidly.. and it didn't explode..
So it was sabotaged. If not, then it must have been fully flooded for
not to implode.. Since Rienzi sank rapidly, it must have flooded unsually
fast to not get imploded when it reached the bottom of ocean..
C) If the Rienzi was not sunk by sabotage, water flooded into it unusually fast.
