单项选择题

The airplane, like many other milestone inventions throughout history, was not immediately recognized for its potential. During the very early 1900s, prior to World War I (1914 - 1918), the airplane was degraded mostly to the county-fair circuit, where daredevil pilots drew large crowds but few investors. One exception was the United States War Department, which had long been using balloons to observe the battlefield and expressed an interest in heavier-than-air craft as early as 1898. In 1908, the Wrights demonstrated their airplane to the U.S. Amay’s Signal Corps at Fort Myer, Virginia. In September of that year, while circling the field at Fort Myer, Orville crashed while carrying an army observer, Lieutenant Thomas Selfridge. Selfridge died from his injuries and became the first fatality from the crash of a powered airplane.
On July 25, 1909, French engineer Louis B16riot crossed the English Channel in a B16riot XI, a monoplane of his own design. Bleriot’s channel crossing made clear to the world the airplane’s wartime potential, and this potential was further demonstrated in 1910 and 1911, when American pilot Eugene Ely took off from and landed on warships. In 1911, the U.S. Army used a Wright brothers’ biplane to make the first live bomb test from an airplane. That same year, the airplane was used in its first wartime operation when an Italian captain flew over and observed Turkish positions during the Italo-Turkish War of 1911 to 1912. Also in 1911, American inventor and aviator Glenn Curtiss introduced the first practical seaplane which was a biplane with a large float beneath the center of the lower wing and two smaller floats beneath the tips of the lower wing.
Which of the following may describe the plane’s first use in a real war

A. A live bomb was dropped from an airplane in 1911.
B. An American pilot took off from and landed on warships in 1910.
C. An Italian pilot flew over to observe the enemy’s position in 1911.
D. The Wrights demonstrated their airplane to the U.S. Army in 1908.
