उत्तर

We cannot use water in case of oil and electric fires. Oil floats over water and thus oil fires cannot be extinguished using water.
Water flows on and it has the risk of spreading the fire along. In case of electric fires water cannot be used as an extinguisher. It being a good conductor of electricity, puts the life of the man spraying it in danger.

Dehra Times

Purkul, 7 July, 09

It is reported that Kareena, a twelve year old girl living in Purkul, went back in time using a time machine.

Seventy years ago her home town was an ideal place to live in. Her home town had not been invaded by the marvels of technology. Industries had not been set up then, so the air was not polluted. She could see children playing in the garden. Some children were listening to the stories told by their grandmothers. Happiness and contentment prevailed everywhere.

Bangle sellers are we who bear
Our shining loads to the temple fair...
Who will buy these delicate, bright
Rainbow-tinted circles of light?
Lustrous tokens of radiant lives,
For happy daughters and happy wives.

How are the bangles described in the first stanza of the poem?


She again rubbed a match on the wall, and the light shone round her; in the brightness stood her old grandmother, clear and shining, yet mild and loving in her appearance. “Grandmother,” cried the little one, “O take me with you; I know you will go away when the match burns out; you will vanish like the warm stove, the roast goose, and the large, glorious Christmas-tree.” And she made haste to light the whole bundle of matches, for she wished to keep her grandmother there. And the matches glowed with a light that was brighter than the noon-day, and her grandmother had never appeared so large or so beautiful. She took the little girl in her arms, and they both flew upwards in brightness and joy far above the earth, where there was neither cold nor hunger nor pain, for they were with God.

In the dawn of morning there lay the poor little one, with pale cheeks and smiling mouth, leaning against the wall; she had been frozen to death on the last evening of the year; and the New-year’s sun rose and shone upon a little corpse! The child still sat, in the stiffness of death, holding the matches in her hand, one bundle of which was burnt. “She tried to warm herself,” said some. No one imagined what beautiful things she had seen, nor into what glory she had entered with her grandmother, on New-year’s day.
