In my opinion, we cannot completely ban keeping the pets but only the ones who have no concept of how to take care of pets, i.e the ones who think of them as 'just animals', rather than making a full and complete commitment to adopt them as our children, as complete and equal family members and keep them safe & healthy should be allowed to keep pets with proper licence and registration. And people who show cruelty against them should also be punished.

During the devastating July 2005 floods that hit Mumbai, Rajen Dutia received an urgent call from a relative, Lopa Vyas late in the evening. “A friend’s mother is stranded near your home, Rajen. Can you please take her home? Her name is Rashmi,” Vyas told him.
Mumbai had come to a halt and people were trapped everywhere. Despite power failure and raging rain, Dutia stepped out and made his way to the spot, where he found Rashmi as well as a dozen other people. They were stranded in the dark, shivering in the rain. They all lived far away and had no place to go for the night.
Rajen took all of them to his one-bedroom flat, where he served them dinner and invited them to spend the night.
"By doing so," says Rajen, "I was simply fulfilling my karma, paying the universe back for the good it had done for me."

"God is kind. My daughter had just started her new job that day, and had gone for her training. She was stranded too. While she was trying to get to our relatives, she almost drowned, but a young stranger saved her. He and his friends even dropped her to my relative's place and phoned me to say she was safe.

Read the passage given below :

1. To ensure its perpetuity, the ground is well held by the panther both in space and in time. It enjoys a much wider distribution over the globe than its bigger cousins and procreates sufficiently profusely to ensure its continuity for all time to come.

2. There seems to be no particular breeding season of the panther, although its sawing and caterwauling is more frequently heard during winter and summer. The gestation period is about ninety to a hundred days (Whipsnade, ninety-two days). The litter normally consists of four cubs, rarely five. Of these, generally, two survive and not more than one reaches maturity. I have never come across more than two cubs at the heels of the mother. Likewise, graziers in the forest have generally found only two cubs hidden away among rocks, hollows of trees, and other impossible places.
 
3. Panther cubs are generally in evidence in March They are born blind. This is a provision of Nature, against, their drifting away from the place of safety in which they are lodged by their mother, and exposing themselves to the danger of their being devoured by hyenas, jackals, and other predators. They generally open their eyes in about three to four weeks.
 
4. The mother alone rears its cubs in seclusion. It keeps them out of the reach of the impulsive and impatient male. As a matter of fact, the mother separates from the male soon after mating and forgets all about their tumultuous union. The story that the male often looks in to find out how the mother is progressing with her cubs has no foundation except in what we wish it should do at least.
 
5. The mother carries its cubs about by holding them by the scruff of their neck in its mouth. It trains them to stalk and teaches them how to deliver the bite of death to the prey. The cubs learn to treat all and sundry with suspicion at their mother’s heels. Instinctively the cubs seek seclusion, keep to cover and protect their flanks by walking along the edge of the forest.
 
6. I have never had an opportunity to watch mother panther train its cubs. But in Pilibhit forests, I once saw a tigress giving some lessons to its little ones. I was sitting over its kill at Mala. As the sunset, the tigress materialized in the twilight behind my machan. For about an hour, it scanned and surveyed the entire area looking and listening with the gravest concern. It even went to the road where my elephant was awaiting my signal. The mahout spotted it from a distance and drove the elephant away.
 
7. When darkness descended upon the scene and all was well and safe, the tigress called its cubs by emitting a low haa-oon. The cubs, two in number and bigger than a full-grown cat, soon responded. They came trotting up to their mother and hurried straight to the kill in indecent haste. The mother spitted at them so furiously that they doubled back to its heels immediately. Thereafter, the mother and its cubs sat undercover about 50 feet (15 m) away from the kill to watch, wait, look, and listen. After about half an hour’s patient and fidget less vigil the mother seemed to say ‘paid for’. At this signal, the cubs cautiously advanced, covering their flanks, towards the kill. No longer did they make a beeline for it, as they had done before.
 
8. The mother sat watching its cubs eat. and mounted guard on them. She did not partake of the meal.

Read the following extract and answer the questions given
below:
Prominent among the urges that inspire and drive a person in life, is the mge to be a somebody. It is quite human, especially in the early stages of life, to want to do something to win laurels and admiration of all around. There's a pitfall though - the very process of becoming a somebody may subtly reduce yon to a nobody.
American poet Emily Dickinson, who lived in obscurity, has an interesting poem on this theme. "I'm nobody!" she declares, with apparent pride.
"Who are you?
Are you nobody, too?"
Why should anybody be happy about being nobody?
The poem explains :
"How dreaiy to he somebody!
How public, like a frog
To tell your name the livelong day
To an admiring bog!
The word 'bog' is significant. When you become a somebody, you invite adulation :
this then begins to bog you down. The moment you think you have arrived, you begin to stagnate, or, worse, your downslide begins. An endless list of writers, artists, sportsmen, politicians ..... fit this pattern of personal history.
To sustain your development in absolute terms, to become a true somebody, it is important to remain a temporal nobody. Even if destiny makes you a temporal somebody,
you should be able to see yourself as merely an agent of a superior power; no more. This requires an exercise of will. You have to constantly watch out and talk to yourself morning and evening.

(1) What is the main idea of the extract? (1)

(2) Why is it important for one to remain a temporal nobody? How? (1)

(3) What does Emily Dickinson declare with pride? Why? (2)

Read the following extract and answer the questions given below.         

            I grew up in India in which telephones were both rare and virtually useless. When I left India in 1975 to go to the US for graduate studies, we had perhaps, 600 million residents in the country and just two million landline telephones. Having a telephone was a rare privilege: if you weren’t an important government official, or a doctor, or a journalist, you might languish in a long waiting list and never receive a phone.

             Telephone were such a rarity (after all, 90% of population had access to a telephone line) that elected members of Parliament had amongst their privileges the right to allocate 15 telephone connections to whomever they deemed worthy.

              And if you did have a phone, it wasn’t necessarily a blessing. I spent my high school years in Calcutta, and I remember that if you picked up your phone, you had no guarantee you would reach the number you had dialled. Sometimes you were connected to someone else’s ongoing conversation, and they had no idea you were able to hear them; there was even a technical term for it, the ‘cross - connection’ (appropriately, since these were connections that made us very cross). If you wanted to call another city, say Delhi, you had to book a ‘trunk call’ in the morning and then sit by the telephone all day waiting for it to come through; or you could pay eight times the going rate for a ‘lightning call’ = but even lightning struck slowly in India those days, so it only took half an hour instead of the usual three or four or more to be connected.
 

Questions:

(1). Why were telephones a rarity before 1975? (1)

(2) What special rights did elected members of Parliament use to have? (2)

(3) How did the author differentiate between a ‘trunk call’ and a ‘lightning call’?  (2)

(4) Do you think the cellphone has made us global?  (2)

(5) Rewrite the following sentences in the ways instructed.  . (3)

(i) You could pay eight times the going rate for a ‘lighting call’. (Rewrite it using modal auxiliary showing compulsion) 

(ii) I spent my high school years in Calcutta. [Rewrite it using past perfect tense] 

(iii) Telephones were a rarity. [Make it a rhetorical question] 

(6) Match the words in column ‘A’ with their meanings in column ‘B’.  (1)

  Column A   Column B
(i) Privilege
(i)
means to reach or get
(ii) Access
(ii)
remedy
    (iii) special right

“And that skeleton,” I asked. “ What about the skeleton in the cupboard? Did you know about it?”
“Yes, I knew about it. But I have no idea whose skeleton it was. You see, back in the twenties, when Green took over this hotel, he had one of his sudden enthusiasms and was convinced this town needed a medical school or college, and he set about preparing the ground for one. He was ready to finance the project, or part of it. And of course medical students need a skeleton. So he acquired one from the Lady Hardinge Medical College in New Delhi. It was a medical school skeleton you found. And if you’d looked closely you'd have noticed that it was varnished.”
“Why was it varnished?” I asked.
“To help preseve it, of course. It was also articulated”
“Articulated?”
“That means the joints were connected up, so that the whole thing wouldn't fall apart. Want to be a doctor, young man?”
“No,” I said. “A detective.”
“Well, you didn't solve this case”.
“I wasn't here. And now we'll never be able to identify the skeleton.”
“Some poor woman of the streets, no doubt. Unclaimed, unwanted. But in the end you gave her a decent burial-even if she wan't a Cristian. Padre Duett is a bit embarrassed, but I've told him I don’t mind my name on the tombstone. I’ll be returning to Africa shortly, and when I die I shall have another tombstone there.

In 1945 in Bay Roberts, Canada, a 12- year old boy saw something in a shop window that set his heart racing. But the price - five dollars- was far beyond Reuben Earle's means. Five dollars would buy almost a week's groceries for his family.

Reuben couldn't ask his father for the money. everything Mark Earle made fishing. Reuben's mother. Dora, stretched like elastic to feed and clothe their five children.

Nevertheless, he opened the shop's weathered door and went inside. Standing proud and straight in his flour-sack shirt and washed out trousers, he told the shopkeeper what he wanted, adding, "but I don't have the money now. can you please hold it for me?"

"I will try," the shopkeeper smiled. "Folks around here don't usually have that kind of money to spend on things. It should keep for a while."

Reuben respectfully touched his worn cap and walked out into the May sunlight. The bay rippled in a freshening wind that ruffled his short hair. There was purpose in his loping stride. He would raise the five dollars and not tell anybody.

Hearing the sound of hammering from a side street. Reuben had an idea.

He ran towards the sound and stopped at a construction site. People built their own homes in Bay Roberts, using nails purchased in burlap sacks from a local factory. Sometimes the sacks were discarded is the flurry of building, and Reuben knew he could sell them back to the factory for five cents apiece.

Case study of museums

1.

We don’t go to museums. We prefer malls, cinema halls, and restaurants. Visiting a museum is best left to schools which makes it mandatory. After all, it is an academic exercise. And what entertainment can these places possibly offer? India doesn’t boast the greatest of museums, but one can’t doubt the collection of artefacts in these repositories of heritage, even for a second. Our eventful history has handed down us numerous masterpieces, but unfortunately, we don’t find them compelling enough. A cultural historian and museologist Jyotindra Jain says that the habit of going to museums has just not been inculcated in us. One of the best museums in the country, the National Museum in Delhi charges a mere Rs. 20. According to Joyoti Roy, outreach consultant, National Museum, it receives between 6,00,000 to 7,00,000 visitors each year and anything between 2,500 and 3,000 per day. The mix includes Indians, foreigners, and school students. For an Indian museum, it is an astounding figure, but still nowhere close to the footfalls museums, we consider the finest, get.

2. It has not been many days since the National Gallery of Modern Art, Bangalore, hosted A. Ramachandran’s expansive retrospective covering five decades of his artistic journey. As we sat outside the first-floor gallery after Ramachandran walked me through his sketches, sculptures, and paintings, the senior artist, a bit disappointed said, “Had an exhibition of this scale taken place abroad, people would have come in thousands.” There were about three-five visitors inside the gallery at that time. Jain, who has also helmed institutions like the Crafts Museum and Indira Gandhi National Centre for the Arts in Delhi, puts the onus on museums. “We developed the museums but didn’t evolve the infrastructure around it. And it is the museum’s responsibility to do it. When you know, people are not going to come to you, you must go to them. Crafts Museum shares its wall with India Trade Promotion Organisation. It receives lakhs of people during the trade fair. I fought tooth and nail to get that door opened during my tenure (1984-89) so that the visitors spill over to the Crafts Museum as well. Museums need to rethink their strategies and outreach should be a major point of concern for them.”
3. In 2010, UNESCO brought out a report on the terrible conditions at India’s top eight museums, citing substandard maintenance, lighting, and signage, among other issues. The Ministry of Culture put together a 14 - point museum reforms agenda and things have moved forward since then. Dr Bhau Daji Lad Museum, the oldest museum in Mumbai has received 3,00,000 visitors over the past year. On average, the museum witnesses 500 visitors every day, with an average of 2,000 visitors over weekends. Not big numbers again, but impressive enough in the Indian context. And this is when the museum re-emerged after a revamp in 2008 with an extensive exhibition programme. Collaborations, screenings of movies of different genres, and workshops for adults and children contributed to the increase in the number of footfalls. The public-private partnership model of the museum is unique and can be replicated in other cases as well.
4. Robust publicity of exhibitions and creating links between different art spaces can also fetch the audience. Different art institutions located in proximity can host a series of events to be held in each one of them simultaneously. Museums also need to transform their cafes, upgrade their museum shops, and most importantly, invest in their human resource. So, what do we do until then? Let’s go and explore these storehouses of history, culture, and knowledge because unless and until we claim them, they will remain indifferent to our needs.

After studying the case study of museums, answer the following questions.

  1. What according to the author is the reason for fewer footfalls in the museums in India?
  2. What measures are suggested in the passage to multiply the visitors to the museums?
  3. What was the proposition given by A. Ramachandran during his tenure at Crafts Museum?
  4. Between the National Museum of Delhi and Dr. Bhau Daji Lad Museum, which museum has more footfall on daily basis? Justify using statistics provided in the study.

Read the passage given below.

5 Changing food preferences have brought about rapid changes in the structure of the Indian diet. The rapid proliferation of multinational fast food companies and the influence of Western culture have replaced traditional home-cooked meals with ready-to-eat, processed foods thus increasing the risk of chronic diseases in urban Indians. Therefore, nurturing healthy eating habits among Indians from an early age would help to reduce health risks.
10 To date, little is known about the quality and quantity of foods and beverages consumed by urban Indian adolescents. This lack of evidence is a significant barrier to the development of effective nutrition promotion and disease prevention measures.

20

 

Therefore, a self-administered, semi-quantitative, 59-item meal-based food frequency questionnaire (FFQ) was developed to assess the dietary intake of adolescents. A total of 1026 students (aged 14-16 years) attending private, English-speaking schools in Kolkata completed the survey.

A sample percentage of the food consumption pattern is displayed.

The survey results report poor food consumption patterns and highlight the need to design healthy eating initiatives. Interestingly, while there were no gender differences in the consumption of legumes and fried snacks, the survey found more females consumed cereals, vegetables and fruits than their male counterparts.

25 In conclusion, the report suggested that schools ought to incorporate food literacy concepts into their curriculum as they have the potential of increasing the fruit and vegetable intake of teenagers. Additionally, healthy school canteen policies with improved availability, accessibility, variety and affordability of healthy food choices would support the consumption of nutritious food in students.

Based on your understanding of the passage, answer the questions given below.

  1. What does the researcher mean by ‘changing food preferences'?
  2. Why was this survey on the food consumption of adolescents undertaken?
  3. With reference to the above figure, write one conclusion about students' consumption of energy-dense drinks.
  4. What can be concluded from the ‘no intake’ data of fruit consumption versus energy-dense snacks, with reference to the above figure?
  5. There were gender differences observed in the consumption of healthy foods, according to the survey. Substantiate.
  6. Why is ‘affordability’ recommended as a significant feature of a school canteen policy?
  7. Identify a word from lines 9-18 indicating that the questionnaire was specifically designed to be completed by a respondent without the intervention of the researcher collecting the data.

November 4, 1851.

Dear Brother John Honston,

When I came to Charleston day before yesterday, I learned that you were anxious to sell the land where you live, and move to Missouri. I have been thinking of this ever since, and cannot but say such an idea is quite foolish. What can you do in Missouri better than here? Is the land any richer? Can you, there, any more than here, raise com and wheat without work? Will anybody there, any more than here, do your work for you? If you intend to go to work, there is no better place than right where you are; if you do not intend to work, you cannot get along anywhere. Crawling about from place to place can do you no good. You have raised no crop this year. What you really want is to sell the land, get the money and spend it. Part with the land you have and my life upon it-never after will you own a spot big enough to bury you. Half of what you will get for the land, you will spend in moving to Missouri, and the other hall you will eat, drink, wear out and no foot of land will be brought. Now I feel it my duty to have no hand in such a piece of foolery.

Now do not misunderstand this letter. I do not write it in any unkindness. I write it in order, if possible, to get you to face the truth which truth is, you are poor and needy because you have idled away your time. Your thousand excuses for not getting along better are all nonsense. They deceive nobody but yourself. To go to work is the only cure for your case.

Affectionately,
Your brother,
Abraham Lincoln.

Read the following passage and do the activities.

A1. Choose the correct option.  (2)

  1. Thousands of birds were killed due to oil spills because ______.
    1. It suffocated them
    2. It was poisonous
    3. Birds couldn't enter the sea
    4. There was no fish to feed on
  2. The primary components of crude oil are ______.
    1. Methane and ethane
    2. Carbon and hydrogen
    3. Sulphur compounds
    4. Naphthalene
During the Gulf War, a few years back, tens of thousands of sea birds were killed due to oil spills. Do you know what makes crude oil on ocean water so deadly?
Crude oil is not used in the state it is produced at the off-shore wells. It is converted in refineries into a wide range of products such as gasoline, kerosene, diesel, fuel oils, and petrochemical feed-stocks. Before it is refined, the oil also contains potentially fatal components.
Crude oil is made up of compounds of carbon and hydrogen called hydrocarbons. These hydrocarbons may be paraffin, the oil that is used as fuel in heaters and lamps or cycloparaffins (naphthenes) or aromatic compounds in varying proportions. While crudes found in the US are mostly paraffinic, these found along the Gulf Coast are naphthenic which contain sulphur compounds in varying amounts, a small amount of nitrogen and very little oxygen. Every variety of crude oil has nickel and vanadium in high concentration. Iron may be found in organic form due to the corrosion of pipes. Paraffins like methane and ethane are asphyxiants, substances that cause suffocation. The effects of cycloparaffins are more or less similar to those of paraffins but unsaturated paraffins are more noxious, than saturated ones. The sulphur present in crude oil may be toxic. The mechanism of toxic action seems to involve its breakdown to hydrogen sulphide. They will act principally on the .nervous system with death resulting mainly from respiratory paralysis. Sulphur in the form of aromatic thiophenes, benzothiophenes can damage the livers and kidneys of sea animals. Sulphur compounds like mercaptens can be very dangerous too.

A2. Crude oil may be toxic and fatal. Justify.  (2)

A3. Rewrite the sentences using one word from the passage for the underlined phrase/word. (2)

  1. Over consumption of alcohol may lead to death.
  2. The flowers displayed at the exhibition differ in properties.
