Task: Question Generation
Input (English): Passage: Sailors on nearby ships heard the series of signals and, realizing that a collision was imminent, gathered to watch as Imo bore down on Mont-Blanc. Both ships had cut their engines by this point, but their momentum carried them right on top of each other at slow speed. Unable to ground his ship for fear of a shock that would set off his explosive cargo, Mackey ordered Mont-Blanc to steer hard to port (starboard helm) and crossed the bow of Imo in a last-second bid to avoid a collision. The two ships were almost parallel to each other, when Imo suddenly sent out three signal blasts, indicating the ship was reversing its engines. The combination of the cargoless ship's height in the water and the transverse thrust of her right-hand propeller caused the ship's head to swing into Mont-Blanc. Imo's prow pushed into the No. 1 hold of Mont Blanc, on her starboard side.The collision occurred at 8:45 am. The damage to Mont Blanc was not severe, but barrels of deck cargo toppled and broke open.  This flooded the deck with benzol that quickly flowed into the hold. As Imo's engines kicked in, she disengaged, which created sparks inside Mont-Blanc's hull. These ignited the vapours from the benzol. A fire started at the water line and travelled quickly up the side of the ship. Surrounded by thick black smoke, and fearing she would explode almost immediately, the captain ordered the crew to abandon ship. A growing number of Halifax citizens gathered on the street or stood at the windows of their homes or businesses to watch the spectacular fire. The frantic crew of Mont-Blanc shouted from their two lifeboats to some of the other vessels that their ship was about to explode, but they could not be heard above the noise and confusion. As the lifeboats made their way across the harbour to the Dartmouth shore, the abandoned ship continued to drift and beached herself at Pier 6 near the foot of Richmond street.Towing two scows at the time of the collision, Stella Maris responded immediately to the fire, anchoring the barges and steaming back towards Pier 6 to spray the burning ship with their fire hose. The tug's captain, Horatio H. Brannen, and his crew realized that the fire was too intense for their single hose and backed off from the burning Mont Blanc. They were approached by a whaler from HMS Highflyer and later a steam pinnace belonging to HMCS Niobe. Captain Brannen and Albert Mattison of Niobe agreed to secure a line to the French ship's stern so as to pull it away from the pier to avoid setting it on fire. The five-inch (127-millimetre) hawser initially produced was deemed too small and orders for a ten-inch (254-millimetre) hawser came down. It was at this point that the blast occurred.
Output (English): What were the full names of the two ships that approached the ship that was burning?
