उत्तर

In humid climates, the moisture in the air acts like a blanket and protects the earth’s surface from the hot rays of the sun. The absence of this blanket in desert lands causes the desert to heat up rapidly during the day and to cool off rapidly at night.

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.
She saw her brother Peterkin
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.

We will ponder your proposition and when we decide we will let you know. But should we accept it, I here and now make this condition that we will not be denied the privilege without molestation of visiting at any time the tombs of our ancestors, friends, and children. Every part of this soil is sacred in the estimation of my people. Every hillside, every valley, every plain and grove, has been hallowed by some sad or happy event in days long vanished. Even the rocks, which seem to be dumb and dead as the swelter in the sun along the silent shore, thrill with memories of stirring events connected with the lives of my people, and the very dust upon which you now stand responds more lovingly to their footsteps than yours, because it is rich with the blood of our ancestors, and our bare feet are conscious of the sympathetic touch. Our departed braves, fond mothers, glad, happy hearted maidens, and even the little children who lived here and rejoiced here for a brief season, will love these somber solitudes and at eventide they greet shadowy returning spirits. And when the last Red Man shall have perished, and the memory of my tribe shall have become a myth among the White Men, these shores will swarm with the invisible dead of my tribe^ and when your children’s children think themselves alone in the field, the store, the shop, upon the highway, or in the silence of the pathless woods, they will not be alone. In all the earth there is no place dedicated to solitude. At night when the streets of your cities and villages are silent and you think them deserted, they will throng with the returning hosts’that once filled them and still lover this beautiful land. The White Man will never be alone.
Let him be just and deal kindly with my people, for the dead are not powerless. Dead, did I say? There is no death, only a change of worlds.

Read the extract given below and answer the question that follow.

When will the shores swarm with the invisible dead of the speaker’s tribe? Why?


But even as he approached the boy, Mr. Oliver sensed that something was wrong. The boy appeared to be crying. His head hung down, he held his face in his hands, and his body shook convulsively. It was a strange, soundless weeping, and Mr. Oliver felt distinctly uneasy.

Well, what’s the matter, he asked, his anger giving way to concern. What are you crying for? The boy would not answer or look up. His body continued to be wracked with silent sobbing.

Oh, come on, boy. You shouldn’t be out here at this hour. Tell me the trouble. Look up.

What did the boy appear to be doing?


Suddenly all the tension seemed to ebb out of my body as the truth of what he said hit me. Confidently, I drew a line a full foot in back of the board and proceeded to jump from there. I qualified with almost a foot to spare.

That night I walked over to Luz Long’s room in the Olympic village to thank him. I knew that if it hadn’t been for him I probably wouldn’t be jumping in the finals the following day. We sat in his quarters and talked for two hours—about track and field, ourselves, the world situation, a dozen other things.

When I finally got up to leave, we both knew that a real friendship had been formed. Luz would go out to the field the next day trying to beat me if he could. But I knew that he wanted me to do my best—even if that meant my winning.
