Directions : In the following questions, you have two brief passages with 5 questions following each passage. Read the pas sages carefully and choose the best answer to each question out of the four alternatives. PASSAGE-II (9. Nos. 196 to 200) Two or three days and nights went by, I reckon I might say they swum by, they slid along so quiet and smooth and lovely. Here is the way we put it in the time. It was a monstrous big river down there - sometimes a mile and a half wide, we ran nights, and laid up and hid daytimes, soon as night was most gone we stopped navigating and tied up - nearly always in the dead water under a towhead, and then cut young cottonwoods and willows, and hid the raft with them. Then we set out the lines. Next we slid into the river and had a swim, so as to freshen up and cool off, then we set down on the sandy bottom where the water was about knee deep and watched the daylight come. Not a sound anywhere - perfectly still – just like the whole world was asleep only sometimes the bullfrogs a cluttering maybe. The first thing to see, looking away over the water was a kind of dull line - that was the woods on t' other side: you couldn't make nothing else out, then a pale place in the sky, then more pale ness spreading around, then the river softened up away off, and wasn't black any more, but gray: you could see little dark spots drifting along ever so far away - trading scows and such things and long black streaks -rafts, sometimes you could hear a sweep creaking or jumbled up voices, it was so still and sounds come so far and by and by you could see a streak on the water which you know by the look of the streak that there's a snag there in a swift current which breaks on it and makes that streak look that way. How did the days and nights go by, according to the writer ?

Long ago, a Brahmin called Haridatta lived in a little village. He was a farmer but the piece ofland he cultivated provided him with so little to survive on that he was very poor. One day, unable to stand the heat of the summer sun, he went to rest for a while under a big tree on his land. Before he could stretch out on the ground, he saw a huge black cobra slithering out of an anthill nearby. The snake then spread his hood and swayed gracefully from side to side. Haridatta was astonished to see this and he thoughts. "This cobra must really be the god of this land. I have never seen or worshipped him before, which is probably why I am not able to get anything from the land. From this day onwards, I will worship him". He hurried back to his home at once and returned with a glass full of milk. He poured it into a bowl and turning to the anthill said, "O ruler of the land. I did not know you were living in this anthili. That is why I have not paid my tribute to you. Please accept my apologies for this omission and accept this humble offering." He then placed the bowl of milk at the entrance of the anthill and left the place. The next day when the Brahmin arrived to work on his land before the sun rose, he found a gold coin in the bowl he had left at the anthill. He was very happy indeed and from that day on, he made it a practice to offer the cobra milk in a bowl each day. The next morning he would collect a gold coin and leave. One day Haridatta had to go to a neighbouring village on business. He asked his son to go to the anthill as usual and leave a bowl of milk for the cobra. The son did as he was told, but when he went to the same spot the next day and collected the gold coin he thought. "This anthill must be full of gold. If I kill the cobra. I can collect all the gold in an instant, instead of having to waste my time coming hero every day." He then struck the cobra with abig stick. The cobra deftiy dodged the blow but bit Haridatta'.s son with his poisonous fangs. The boy soon died. When Haridatta returned to his village the next day, he heard how his son had met his death. He realised'at once that his son's greed would probably have caused him to attack the cobra. The Brahmin went to the anthill the day after his son's cremation and offered milk to the cobra as usual. This time, the cobra did not even come out of his hole. Instead, he called out to Haridatta. You have come here for gold, forgetting that you have Just lost a precious son and that you are in mourning. The reason for this is pure greed. From today, there is no meaning to our relationship. I am going to give you a diamond as a final gift. But please don't ever come back again." He slithered away as the Brahmin watched. Which of the following is TRUE according to the story?
