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.

“And you had to leave them?” I asked.
“Yes. Because of the artillery. The captain told me to go because of the artillery.” “And you have no family?” I asked, watching the far end of the bridge where a few last carts were hurrying down the slope of the bank.

Why did the soldier tell the old man that it was not a good place to stop?


This woman had been despised, scoffed at, and angrily denounced by nearly every man, woman, and child in the village; but now, as the fact of, her death was passed from lip to lip, in subdued tones, pity took the place of anger, and sorrow of denunciation.

Neighbours went hastily to the old tumble-down hut, in which she had secured little more than a place of shelter from summer heats and winter cold: some with grave-clothes for a decent interment of the body; and some with food for the half-starving children, three in number. Of these, John, the oldest, a boy of twelve, was a stout lad, able to earn his living with any farmer. Kate, between ten and eleven, was bright, active girl, out of whom something clever might be made, if in good hands; but poor little Maggie, the youngest, was hopelessly diseased. Two years before a fall from a window had injured her spine, and she had not been able to leave her bed since, except when lifted in the arms of her mother.

“What is to be done with the children?” That was the chief question now. The dead mother would go underground, and be forever beyond all care or concern of the villagers. But the children must not be left to starve.
