1)What kind of underwater device was used to investigate the ocean before submersible boats were invented?

Answer: primitive diving bell
Keywords: underwater device, investigate the ocean and before submersible boats were invented
Explanation: Ocean is full of secrets so to investigate what’s beneath ocean divers used to go deep in the ocean to find and study. It was a cylindrical structure which was hollow and space for divers. Before use of primitive bells there was much loss of life and little success, after use of bells this was lowered.
Supporting statements: Several clever and innovative people had experimented with designs for submersible boats before then, but there was much loss of life and little success, there had long been use of a primitive diving bell for exploratory purposes.

2)What was the crewman of the first American-built submarine trying to do before his mission failed?

Answer: fasten explosive devices
Keywords: crewman, first American-built submarine and trying to do it before his mission failed.
Explanation: the submarines were made for use in war as weapons, the first American submarine was used against the British at the time of war. The pilot was ready to launch explosives for attack against Britishers which eventually failed as the pilot lost control of the ship.
Supporting statements: use against the British during this war, fasten explosive devices to British ships before losing control of his vessel

3)What gave the Nautilus the ability to remain submerged for a long time?

Answer: compressed air (system)
Keywords: Nautilus, gave ability and remained submerged for a long time
Explanation: submarine's ballast tanks are filled with air which gives the vessel its buoyancy and in order for the submarine to submerge water is taken into the ballast tanks through the flood ports at the bottom of the tanks, effacing this excess buoyancy and submarine is submerged, to get a submarine to surface, the main vents in the top of the tank are closed and high-pressure compressed air is blown into the ballast tanks, forcing the water out through the flood
Supporting statements: ports at the bottom of the tank. This increases the vessel's displacement and submarine gets on surface. This version brought in features that can still be found in some modem submarines, notably adjustable diving planes for better underwater manoeuvring, dual systems of propulsion

4)When was a submarine first used successfully to sink an enemy boat?

Answer: 1864
Keywords: submarine, first used successfully and sinking an enemy boat.
Explanation: after lots of unsuccessful failures 1864 was the year when the American navy found success as they sank a ship in Charleston Harbour. They launched torpedoes successfully and Its potential had been recognised which means a successful attack was carried out.
Supporting statements: Its potential had been recognised, it was commissioned again in 1864 to attack a ship in Charleston Harbour, but the submarine never reappeared, and once again the whole crew perished. Its potential had been recognised

5)What new type of propulsion did the Holland use on top of the water?

Answer: gasoline (engine)
Keywords: new type of propulsion, the Holland and on top of the water
Explanation: After seeing failures before by other scientists, the US Navy held a competition which was won by John Holland. It was his sixth design which got success and got selected which worked on gasoline it used to turn a propeller while the vessel was on the surface. When it submerged, the engine ran a generator to charge batteries to operate an electric motor. This was the principle used by John Holland for submarines.
Supporting statements: When it submerged, the engine ran a generator, t was propelled by a gasoline engine that turned a propeller while the vessel was on the surface,

6)For what reason was Diesel’s fuel considered safer than Holland’s?

Answer: less explosive / volatile
Keywords: reason, Diesel’s fuel, safer and then Holland’s
Explanation: the diesel’s fuel was considered because it was not explosive and safe to store also there was no necessity for an electric spark to ignite the fuel. On the other hand, gasoline fuel was more explosive and caused hazards to crewmen so it was replaced for safety purposes.
Supporting statements: less explosive than gasoline, consequently be stored safely, advantage was that there was no necessity for an electric spark to ignite the fuel.

Questions 7:

Answer: sailplanes
Keywords: two sets, diving planes, the forward,
Explanation: in paragraph 9 it is mentioned that there are two sets of diving plates which suggest that the plane present in forward must be sailplanes and in the picture we can see the plane is in the forward side so it clearly depicts that it is sailplanes.
Supporting statements: there are two sets of diving planes

Questions 8:

Answer: periscope
Keywords: conning tower, tall fin-shaped sail, captain can see
Explanation: in paragraph 8 it is given that it is a scope through which the captain can see the sea and sky when the submarine is near the surface of the water and its position is Inside the sail is the conning tower so we can say that it is periscope.
Supporting statements: Inside the sail is the conning tower, through which the captain can see the sea and sky

Questions 9:

Answer: radio antenna
Keywords: Sonar, navigation, projection
Explanation: unlike periscope which is used to see which must be placed in front so we can say that behind it there is a radio antenna also the other projection from the conning tower means other than periscope radio antenna is present.
Supporting statements: The other projection from the conning tower, tall fin-shaped sail that comes up out and extending from this

Questions 10:

Answer: rudder
Keywords: tail fin, side-to-side, controls
Explanation: in paragraph 9 it says that two controls control movement so it is clear it must be rudder as it is also positioned behind the submarine for movement.
Supporting statements: there are two controls for steering the submarine

Questions 11:

Answer: propeller
Keywords: back, rudder
Explanation: at the end of paragraph 9 it clearly explains the position of the problem with the rudder at the back side.
Supporting statements: located at the back with the rudder

Questions 12:

Answer: stem planes
Keywords: two set
Explanation: In paragraph 9 it is said that there are two sets of plate which means one is sailplanes and the other is stem planes
Supporting statements: the forward sailplanes and the stem planes,

Questions 13:

Answer: outer hull
Keywords: largest part
Explanation: In paragraph it is given that outer hull is largest part and from diagram we can see that the biggest part is 13 which says that the 13 is outer hell
Supporting statements: The outer hull is the largest part of the boat and forms the body
