Read the passage and answer the multiple-choice questions.

In 1863, the French writer Ponton D'Amecourt was the first person to create the word "helicopter" from the two words "helico" for spiral and "pter" for wings. The very first helicopter was invented by Paul Cornu in 1907, but it was not successful. French inventor, Etienne Oehmichen built and flew a helicopter one kilometer in 1924.

However, Igor Sikorsky is considered to be the father of helicopters not because he invented the first. He is called that because he invented the first successful helicopter, upon which further design were based. One of aviation's greatest designers, Russian born Igor Sikorsky began work on helicopters as early as 1910. By 1940, Igor Sikorsky's successful VS-300 had become the model for all modern helicopters of today. He also designed and built the first military helicopter.

Igor Sikorsky's helicopters had the control to fly safely forwards and backwards, up and down, and sideways. In 1958, Igor Sikorsky's company made the world's first helicopter that could land and take off from water. It could also float on the water.

HISTORY OF THE HELICOPTER

Although first flight generally attributed to a fixed-wing aircraft, the helicopter actually represents the first style of flight envisioned by humans. The ancient Chinese developed a toy that rose upward when spun rapidly. As early as the mid-sixteenth century, the great Italian inventor Leonardo da Vinci had drawn a prototype for the machine that we now know as the helicopter.

Early in the twentieth century, a great deal of experimentation and revision was taking place with regard to helicopter flight. The well-known phrase “two steps forward and one step back” provided an apt descriptor for early flight development. Uneven lift, known as dissymmetry, caused the early helicopters to flip over and confounded the inventors until the creation of the swash-plate; this allowed the rotor blade angles to be changed so that lift would be equal on each side of the shaft.

On November 13, 1907, the French pioneer Paul Cornu made history by lifting a twin-rotor helicopter into the air for a few seconds without ground assistance. Several models followed without significance until in 1924 when another French pioneer, Etienne Oehmichen, became the first to fly a helicopter for one kilometer. It was a historic flight of 7 minutes and 40 seconds. By 1936, solutions have been found to many of the problems with helicopter flight.

With the introduction of the German Focke-Wulf Fw 61, the first practical helicopter became a reality.

 

The word “envisioned” in paragraph 1 is closet in meaning to _____.

A. imagined 

B. perfected 

C. experienced 

D. taught
