unsinkable Ship Naval architects never claim that a ship is unsinkable, but the sinking of the passenger•and-car ferry Estonia in the Baltic surely should never have happened. It was well designed and carefully maintained. It carried the proper number of lifeboats. It had been thoroughly inspected the day of its fatal voyage. Yet hours later, Estonia rolled over and sank in a cold, stormy night. It went down so quickly that most of those on board, caught in their dark, flooding cabins, had no chance to save the natives. Of those % who managed to scramble overboard, only 139 survived. The rest died of hypothermia before the rescuers could pluck them from the cold sea. The final death toll amounted to 912 souls. One can understand from the reading that .

a) The lifesaving equipment did not work well and lifeboats could not be lowered

b) 139 people managed to leave the vessel but died in freezing water

c) Naval architects claimed that the Estonia was unsinkable

d) Most victims were trapped Inside the boat as they west' In theiir Cabin
