Question

Have you ever wondered how people travel to islands without any airports? Perhaps you have pondered how the coast guard rescues people from a sinking ship. Seaplanes are often the best solution to these challenges. Seaplanes are airplanes designed to take off from and land on top of a body of water. The three different types of seaplanes are flying boats, floatplanes, and amphibians.
2Flying boats have a fuselage, or body, that looks and acts like a ship’s hull. This hull enables them to float on water very easily. Two small floats underneath its wings keep the flying boat stable in rough water. These seaplanes are usually larger and more stable on water than floatplanes are. A floatplane is a seaplane that has two long floats, called pontoons, under the fuselage. This is the only part of the plane that touches the water. Unlike flying boats, floatplanes often come in a wide variety of sizes. An amphibious vehicle can be either a flying boat or a floatplane with wheels. This allows the aircraft to land on both land and water.

3People have used seaplanes for almost a hundred years. French engineer Henri Fabre invented the first seaplane in 1910 and a number of other designs quickly followed. Right from the start, the military recognized the usefulness of these aircraft. During World War I, the military used seaplanes to patrol the seas for enemy submarines. In World War II, military officials used seaplanes for a number of important tasks. While officers still used them to patrol for submarines, they also used seaplanes to scout the positions of ships and other aircraft. They were important tools during search-and-rescue operations.

4After World War II, military use of seaplanes declined. One of the disadvantages of using seaplanes is that they weigh much more than ordinary land-based aircraft and helicopters. This limits the amount of cargo seaplanes can carry. Another factor in the seaplane’s decline was that more airports and landing strips were available to regular airplanes once the war ended. These aircraft were more practical and easier to control than seaplanes. This all led to the decline of the seaplane in recent years.

5Though militaries no longer use seaplanes regularly, they still fulfill many purposes. Coast guards around the world use seaplanes during rescues because of their ability to fly long distances while searching for stranded people in the water. Fire fighters also use these planes to drop large amounts of water over forest fires. Even airline companies even use seaplanes to fly passengers to remote areas where airstrips do not exist.

6Keep your eyes open next time you find yourself near a large body of water and you might be lucky enough to spot a seaplane flying your way. These aircraft are impressive inventions.

Answer 1

Im not sure but i think it is c

Answer 2

For the first question: According to the passage, which of these is true about seaplanes?

The correct answer would be option C: "They can land in places other planes cannot", this is explained in the first paragraph of the excerpt, it says that seaplanes can land in large bodies of water, where other planes cannot.

Option A and B are incorrect because it clearly says in the excerpt that one of the seaplane's disadvantages is that they cannot carry large shipments of cargo and that other planes are more practical. Option D is also incorrect because it says in the beginning of paragraph 5 that the military doesn't use them that often anymore.

For the second question: Why do airline companies find seaplanes useful?

The correct answer would be option C: "They can transport passengers to remote locations", this is mentioned in the excerpt in paragraph 5. Option A is incorrect because it is not mentioned in the excerpt, option D is incorrect because that is useful for fire fighters not airlines, and option B is incorrect because that was useful for the military.

For the third question: Which choice BEST summarizes the authors comparison of flying boats to floatplanes?

The correct answer would be option C: "Flying boats are larger than floatplanes, and unlike floatplanes, the entire fuselage can float", since floatplanes only have 2 long floats that are the only part of the plane that touches the water.

Option A is incorrect because Flying boats are larger and have floats under their wings and floatplanes do not. Option B is incorrect because Float planes are the ones that have two long floats called pontoons. Option D is incorrect because floatplanes are the ones that have several sizes and neither Flying boats or Floatplanes have wheels.
