Reading Comprehension:

Text – I
Let’s now read the story of a bus conductor and his passengers with a dog. The story is written by A. G Gardiner.

All about a Dog:
It was a bitterly cold night, and even at the far end of the bus the east wind that raved along the street cut like a knife. The bus stopped and two women and a man got in together and filled the vacant places. The young woman was dressed in sealskin, and carried one of those little Pekinese dogs that women in sealskin like to carry in their laps. The conductor came in and took the fares. Then his eyes rested with old malice on the beady eyed toy dog. I saw trouble brewing. This was the opportunity for which he had been waiting and he intended to make the most of it. I had marked him as the type of what Mr. Wells has called the Resentful Employee, the man with a great vague grievance against everything and a particular grievance against passengers who came and sat in his seat while he shivered at the door.
“you must take that dog out,” he said with sour venom.
“I shall certainly do nothing of the kind. You can take my name and address,” said the woman, who had evidently expected the challenge and knew the reply.
“You must take the dog out- that’s my orders.”
“I won’t go on the top in such weather. It would kill me,” said the woman.
“Certainly not,” said her lady companion, “You’ve got a cough as it is.”
“It’s nonsense,” said her male companion.
The conductor pulled the bell and the bus stopped. “This bus doesn’t go until that dog is brought out.” And he stepped on to the pavement and waited. It was his moment of triumph. He had the law on his side and the whole bus full of angry people under the harrow. His embittered soul was having a real holiday.

The storm inside rose high “Shameful!” “He’s no better than a German.” “Why isn’t he in the army ?” “Call the police. Let’s all report him.” “Let’s make him give us our fares back.” Everybody was on the side of the lady and the dog.

That little animal sat blinking at the dim lights in happy unconsciousness of the rumpus of which he was the cause. The conductor came to the door, “What’s your number ?” said one, taking out a pocket- book with a gesture of terrible things. “There’s my number,” said the conductor imperturbably. “Give us bur fares back.” “You can’t leave us here all night.” “No fares back,” said the conductor.

Two or three passengers got out and disappeared into the night. The conductor took another turn on the pavement, then went and had a talk with the driver. Another bus, the last on the road, sailed by indifferent to the shouts of the passengers to stop, ‘They stick by each other the villains,” was the comment.

Someone pulled the bell violently. That brought the driver round to the door, “Who’s conductor of this bus ?” he said and paused for reply. “None coming,” he returned to his seat, and resumed beating his arms across his chest. There was no hope in that quarter. A policeman strolled up and looked in at the door. An avalanche of indignant protests and appeals burst on him. “Well, he’s got his rules, you know,” he said. “Give your name and address.” “That’s what he’s been offered, and he won’t take it.” “Oh,” said the policeman, and he went away and took his stand a few yards down the street, where he was joined by two more constables.

And still the little dog blinked at the lights, and the conductor walked to and fro on the pavement, like a captain on the quarterdeck in the hour of victory. A young woman, whose voice had risen high above the gale inside, descended on him with an air of threatening and slaughter. He was immovable as cold as the night, and as hard as the pavement. She passed on in a fury of impotence to the three policemen, who stood like a group of statuary on the street watching the drama. Then she came back, imperiously beckoned to her ‘young man’ who had sat a silent witness of her rage, and vanished. Others followed. The bus was emptying. Even the dashing young fellow who had demanded the number and who had declared he would see this thing through if he sat there all night, had taken an opportunity to slip away.

Meanwhile the Pekinese party was passing through every stage as of resistance to abject surrender. “I’ll go on the top.” said the sealskin lady at last. “You mustn’t.” “I will.” “You’ll have pneumonia.”

“Let me take it.” (This from the man) “Certainly not.” She would die with her dog. When she had disappeared up the stairs, the conductor came back, pulled the bell, and the bus went on. He stood sourly triumphant while his conduct was savagely discussed in his face by the remnant of the party.

Then the engine struck work, and the conductor went to help the driver. It was a long job and presently the lady with the dog stole down the stairs and re-entered the bus. When the engine was put right, the conductor came back and pulled the bell. Then his eyes fell on the dog, and his hand went to the bell-rope again. The driver looked around, the conductor pointed to the dog, the bus stopped, and the struggle recommenced with all the original features – the conductor walking the pavement, the driver smacking his arms on the box, the little dog blinking at the lights, the sealskin lady declaring that she would not go on the top and finally going.

“I’ve got my rules,” said the conductor to me when I was the last passenger left behind. He had won his victory, but felt that he would like to justify himself to somebody. “Rules,” I said,“ are necessary things, but there are rules and rules. Some are hard and fast rules, like the rules of the road, which cannot be broken without danger to life and limb. But some are only rules for guidance, which you can apply or wink at, as common sense dictates, like that rule about the dogs. They are not a whip, put in your hand to scourge your passengers with, but an authority for an emergency. They are meant to be observed in the spirit, not in the letter, for the comfort and not the discomfort of the passengers. You have kept the rule and broken its spirit. You may mix your rules with a little goodwill and good temper.” He took it very well and when I got off the bus he said “Good night” quite amiably.

Now, complete the box narrating the story in the correct sequence.

Grammar:

A. Phrasal verbs:
The sentence below is taken from the text you have read. The phrase in italic is a phrasal verb. A phrasal verb is a combination of words (a verb + a preposition, for example check in or a verb + an adverb, for example break down). When they are used together, they usually take on a different meaning to that of the original verb.
… Walk away from the old Dakota.
walk away is a phrasal verb which means to move away from.

Find out the meaning of the following phrasal verbs and use them appropriately in sentences.
Answer:

B. The Passive:
Compare the two sentences given below:
Ramesh painted the walls.
The walls were painted by Ramesh.
The first sentence is in active form and the second sentence is in passive form. When the person doing the action (Ramesh) is the subject, we use the verb in the active voice. When the subject is what the action is directed at (the walls), we use the verb in the passive voice. In the first sentence, we talked about Ramesh but in the second sentence we talked about what happened to the walls.

In the passive sentence we use by+agent to add important information, that is by Ramesh. We can leave out by+agent if it does not provide any specific information.

Example:
All the students were given sweets yesterday.
My room is cleaned everyday in the morning.
A large number of films on wildlife conservation have been made.

Question 1.
Do you like riddles? Riddles make us think and attempt to solve puzzles through various ways and means. Read this riddle out loud and find answers to it. You can also discuss with your friends. You will notice that we speak out what we think. This is known as Think-aloud protocol. As you solve the riddles, speak out all the ideas that come to your mind to solve it.
Riddle 1
A farmer returns from the market, where he bought a goat, a cabbage and a wolf (what a crazy market). On the way home he must cross a river. His boat is small and won’t fit more than one of his purchases. He cannot leave the goat alone with the cabbage (because the goat would eat it), nor he can leave the goat alone with the wolf (because the goat would be eaten).
How can the farmer get everything on the other side in this river crossing puzzle?
Answer:
First the farmer will take the goat with him in the boat and drop him on the other side of the river. Then he will row back to the other side. Next he will take the cabbage with him to the other side. He will drop the cabbage there and bring back the goat with him. On reaching the other side with the goat he will drop the goat there and take wolf with him to be dropped to the other side of the river. He’ will leave the cabbage with the Tiger and then start his reverse journey. Finally on reaching the destination he will pick the goat and take it with him to the other side.

Riddle 2

On reaching the other side, he will take another small monkey with him and start, his forward journey to the other side. After dropping the small monkey to that side he will start off for his reverse journey to the other side. On reaching the other side, he will pick one human and start off with him on his forward journey to the other side of the river. On reaching the other side, he will drop the man there and row back the small monkey to the other side.

On reaching the other side the man in the boat will pick one more human and start with him on his forward journey to the other side of the river. On reaching that side, the man in the boat will drop him on that side. Then he will start off for his reverse journey to the other side of the river. On reaching the other side, he will pick one small monkey and start off for his forward journey to the other side of the river.

Article Writing
Question 1.
‘Rules are meant to be observed in spirit not only in letter’. Explain what you understand by this statement. Write an article in about 120-150 words on how the rules can be effectively implemented in the society and citizens can follow it in the true spirit. You may use any of the ideas given in the box. Follow the stages involved in the process approach to writing.
(a) Use it in the context of gender (protection of women’s rights / dowry/ female infanticide, etc.).
(b) In the context of environment (cutting of trees / poaching / pollution).
(c) Smoking in public / following traffic rules, etc. (add cartoons with fun facts, for example parking in front of no parking sign).
(d) In the context of value and self discipline.
Answer:
‘Rules are meant to be observed in spirit not only in letter’. This statement dictates and expects people to not only obey the literal interpretation of the letter (words) of the law but majorly the intentions of those who wrote the law. There are certain areas and situation where the stringent application of the law may have detrimental consequences. The main idea behind formulation of various laws/rules/regulations and their enforcement it to enforce discipline amongst the citizens. Laws are put in place for the convenience of the people and for safeguarding their interests. If the laws are observed only in letter and not in spirit, the whole purpose of law-making is lost.

Satisfactory application of laws should invariably result in peace and harmony in the nation and should not breed agitation and discontent amongst people. In the story. “All about a dog” the behaviour of the conductor was unreasonable and unjustified. His forcing the harmless little dog out of the bus at the cost of the passengers’ convenience was inappropriate. It resulted into a of cascade unpleasant consequences.

As per my understanding dogs are not allowed inside a bus as they might cause inconvenience and rumpus. But the dog in the story was well behaved and didn’t cause any nuisance to the passengers. So forgoing the strict observation of the letter of the law would have not been a serious breach. It is, however, mandatory that laws regarding the protection of women’s rights, protection of environment, traffic rules are strictly enforced. Those who don’t observe these rules must be penalised. In a nutshell, the laws that ensure value and self-discipline must be followed in the right spirit.

Story Writing:

Question 2.
You have read and experienced how the little seagull learnt to fly and then the story Of the mysterious black aeroplane. You have also read the story, ‘All about a dog*. How were these experiences ? You may have also experienced some such situations in your life: learning to ride on a bicycle, watching a cat or any other animal trying to jump over the wall, your own bitter experience in a difficult situation, etc. Think of such an experience and write down the points and develop the ideas into an outline. Write your experiences like a short story.
Answer:
All the three stories mentioned in the question had a common theme. They all had an underlying message that hardwork invariably brings success. Despite the harsh circumstances, if one is determined and committed to a task he/she would definitely gain success at it. All the three stories were quite encouraging and motivating.

The relentless Beetle:
One rainy afternoon, I was sitting in my Verandah to enjoy the lovely weather outside. It was quite mesmerizing to sit in the lap of nature, noticing and admiring its beauty. Tiny drops of water on the leaves of the tree looked like shiny pearls. The birds with their young ones comfortably sheltered in the nest was a wonderful sight. Suddenly, out of the comer of my eye, I noticed something crawling along one of the concrete pillars of the verandah. It was a beetle, a tiny-little, brownish black creature. From what it appeared to me I made out that it was constantly trying hard to reach the middle of the pillar that led to a hole. That was may be its dwelling place. It was facing difficulty moving against the slippery wall.

For every 3 steps forward it would fall 2 steps backwards. I knew the next few minutes of this activity were going to be exciting. I kept my eyes glued to each and every activity of the beetle. Despite the harsh circumstances that it was facing it didn’t lose hope. It continued its efforts with the unrelenting vigour. It was determined in its efforts. Finally after a period of struggle for a couple of minutes the beetle managed to reach the hole. The whole experience was quite motivating for me. It added to my joys and made the whole atmosphere around me even more positive. I greatly admire the courage and relentless attitude of the little creature. That incident made be realise that learning can come in a variety of ways from sources beyond your imagination. I feel all of us must learn from such beautiful experiences and apply that learning in our daily lives to make is more successful.

Project:

Question 1.
You have learnt about the freedom struggles of many nations after the Second World War and the many leaders who spearheaded freedom movements in their countries. Based on the learning from history and political science, write about any two leaders from different nations.

Question 2.
Go around your neighbourhood and talk to people, particularly elders, and collect riddles and puzzles in their languages.

  • Ask them how and why such riddles could have emerged.
  • Collect at least 10 – 15 riddles and write them in an order with information.
  • Find out more about the riddle.
  • Present it to the class as a chart and oral presentation.

Answer:
A riddle is a statement, a question or a phrase having a double or veiled meaning, put forth as a puzzle to be followed.
(1) Enigmas – problems generally expressed in metaphorical or allegorical language that require ingenuity and careful thinking for their solution.

(2) Conundra – Questions relying for their effects in punning in either the question or the answer.
I, personally, am very fond of solving riddles for the fact that they nurture creativity and aid in sharpening the analytical skills. I have collected few riddles from the elders of my neighbourhood. As told by them these riddles were passed on from generation to generation by word of math. In the earlier times when people didn’t have the modern gadgets at their disposal for entertainment this ‘fun activity’ of asking riddles from one another, sharing jokes came to their rescue. Unlike today’s time people could be often seen spending quality time in each other’s company engaging themselves in such recreational activities during their leisure time. Many of us must have had the pleasure of learning about such riddles from our grandparents in the comfort of our homes.

Riddle 1:
There were flocks of sparrows sitting on two different trees. One sparrow from one flock said to the other flock perching on the other tree, “if one of you come and join our flock, our number would become same as yours.” In reply a sparrow from the other flock said, “if one of you joins our fock our number would be twice as yours.” How many birds were there in each of the flocks ?
Answer:
There were 5 sparrows in one flock and 7 in the other one.

Riddle 2:
Two Hourglasses : You have two sand hourglasses, one that measures exactly 4 minutes and one that measures exactly 7 minutes. You need to measure out exactly 2 minutes to boil an egg. Using only these two hourglasses, how can you measure out exactly 2 minutes to boil your egg ?
Answer:
Flip over both hourglasses at the same time. After 4 minutes, the 4-minute hourglass will be done, and there will be 3 minutes left in the 7-minute hourglass. Immediately flip the 4-minute hourglass over again. After 3 more minutes, the 7-minute hourglass will be done, and there will be exactly 1 minute left in the 4-minute hourglass. Immediately flip the 7-minute hourglass over again. After 1 more minute, the 4-minute hourglass will be done again, and there will be exactly 6 minutes left in the 7- minute hourglass. Immediately flip over the 4-minute hourglass. After 4 more minutes, the 4-minute hourglass will be done again, and there will be exactly 2 minutes left in the 7-minute hourglass. At this point, put your egg in the boiling water. When the 7- minute hourglass is done, it will have been exactly 2 more minutes, and your egg will have boiled just right.

Riddle 3:
I have two rectangular wires.
Both of them have property that when I light the fire from one end, it will take 60 minutes to get completely burn.
However they do not burn at consistent speed (i.e., it might be possible 1st 20% burn in 50 minutes and 80% can burn in 10 minutes).
So how could I measure 45 minutes?
Answer:
Steps : (A) burn 1st wire from both end and 2nd wire from one end
(B) After 30 minutes (when 1st wire gets completely burned out), burn the second wire from 2nd end as well
(C) when 2nd run completely gets burned, you know its 45 minutes.
