Q1 Read the following passage and answer the questions.
The History of Hot-air Balloons.
The conquest of the upper atmosphere and outer space would not have been possible without the endeavours made by adventurous balloonists. It took a great deal of courage for the first man to step into a tiny basket and rise high into the air.
On June 1783, the French papermakers Joseph-Michael Montogolfer and Jacques Elenne Montgolfer, built a large fire over which they placed a massive balloon of linen and paper. As soon as the air under the balloon heated up, the balloon inflated and began to rise. The people who watched this fascinating feat were completely awestruck.
On 9 September of the same year, the brothers launched yet another hot-air balloon. It was brightly coloured and the attached basket carried a duck, a rooster and a sheep. The balloon rose high into the air and landed back safely, but when the balloon hit the ground, the sheep fell on top of the rooster and broke one of its wings!
Encouraged by the success of these two trips, on 21 November, De Rozier and Marquis De Arlandes became the first humans ever to travel in air. Their 25-minute flight covered approximately nine kilometers and attained an altitude of 3,000 feet before landing on the outskirts of Paris.
One of the most daring and tragic flights was undertaken in 1927 by Captain Gray, an American flyer and scientist. On 4 November, he flew up into the atmosphere in an open gondola and a little later the ground crew lost sight of him. As he travelled higher and higher, he kept noting down how his body was reacting to the atmosphere. He wrote that he trembled at 10,000 feet and he was compelled to use his oxygen mask. When he sailed 31,000 feet above the sea level, the temperature dropped to minus 32 degrees centigrade. It was evident from his writings that his hands trembled and his mind became foggy. As the balloon soared even higher, Gray began losing consciousness before he breathed his last. The brave balloonist’s balloon bag and gondola were found near Sparta, Tennesse. His barometer had last recorded a height of 42,740 feet.
