उत्तर

Oxygen is one of the three elements essential for causing fire. If we can disrupt the supply of oxygen then we can put of the fire.
This can be applied in case of small fires. If we throw a damp blanket or a sack over the fire, it cuts off the supply of oxygen and the fire is immediately put off.

It was a summer evening,
Old Kaspar's work was done,
And he before his cottage door
Was sitting in the sun,
And by him sported on the green
His little grandchild Wilhelmine.

Roll something large and round,
Which he beside the rivulet
In playing there had found;
He came to ask what he had found,
That was so large, and smooth, and round.

It was my business to cross the bridge, explore the bridge head 3 beyond and find out to what point the enemy had advanced. I did this and returned over the bridge. There were not so many carts now and very few people on foot, but the old man was still there.’’Where do you come from?” I asked him.
“From San Carlos,” he said, and smiled.
That was his native town and so it gave him pleasure to mention it and he smiled.
“I was taking care of animals,” he explained.
“Oh,” I said, not quite understanding.
“Yes,” he said, “I stayed, you see, taking care of animals. I was the last one to leave the town of San Carlos.”
He did not look like a shepherd nor a herdsman and I looked at his black dusty clothes and his gray dusty face and his steel rimmed spectacles and said, “What animals were they?”
“Various animals,” he said, and shook his head. “I had to leave them.”

The village consisted of less than thirty houses, only one of them built with brick and cement. Painted a brilliant yellow and blue all over with gorgeous carvings of gods and gargoyles on its balustrade, it was known as the Big House. The other houses, distributed in four streets, were generally of bamboo thatch, straw, mud, and other unspecified material. Muni’s was the last house in the fourth street, beyond which stretched the fields. In his prosperous days Muni had owned a flock of forty sheep and goats and sallied forth every morning driving the flock to the highway a couple of miles away.

What is the name of the village referred to here? Where is it situated?


“Jane,” said the wheelwright, with an impressiveness of tone that greatly subdued his wife, “I read in the Bible sometimes, and find much said about little children. How the Savior rebuked the disciples who would not receive them; how he took them up in his arms, and blessed them; and how he said that ‘whosoever gave them even a cup of cold water should not go unrewarded.’ Now, it is a small thing for us to keep this poor motherless little one for a single night; to be kind to her for a single night; to make her life comfortable for a single night.”

The voice of the strong, rough man shook, and he turned his head away, so that the moisture in his eyes might not be seen. Mrs. Thompson did not answer, but a soft feeling crept into her heart.

“Look at her kindly, Jane; speak to her kindly,” said Joe. “Think of her dead mother, and the loneliness, the pain, the sorrow that must be on all her coming life.” The softness of his heart gave unwonted eloquence to his lips.

What brought eloquence to Joe’s lips when he spoke to his wife?


It was the summer of 1936. The Olympic Games were being held in Berlin. Because Adolf Hitler childishly insisted that his performers were members of a “master race,” nationalistic feelings were at an all-time high.

I wasn’t too worried about all this. I’d trained, sweated and disciplined myself for six years, with the Games in mind. While I was going over on the boat, all I could think about was taking home one or two of those gold medals. I had my eyes especially on the running broad jump. A year before, as a sophomore at the Ohio State, I’d set the world’s record of 26 feet 8 1/4 inches. Nearly everyone expected me to win this event.

Who is Jesse Owens?


I was in for a surprise. When the time came for the broad-jump trials, I was startled to see a tall boy hitting the pit at almost 26 feet on his practice leaps! He turned out to be a German named Luz Long. 1 was told that Hitler hoped to win the jump with him. I guessed that if Long won, it would add some new support to the Nazis’ “master race” (Aryan superiority) theory. After all, I am a Negro. Angr about Hitler’s ways, 1 determined to go out there and really show Der Fuhrer and his master race who was superior and who wasn’t. An angry athlete is an athlete who will make mistakes, as any coach will tell you. I was no exception. On the first of my three qualifying jumps, I leaped from several inches beyond the takeoff board for a foul. On the second jump, I fouled even worse. “Did I come 3,000 miles for this?” I thought bitterly. “To foul out of the trials and make a fool of myself ?” Walking a few yards from the pit, 1 kicked disgustedly at the dirt.
