Dear Sir Subject : Cleanliness initiative on Gandhi Jayanti

Through the columns of your esteemed newspaper, I, as a concerned citizen of the

nation, would like to reflect upon the recent initiative by the Prime Minister of India whereby Gandhi Jayanti was celebrated as a Cleanliness Day.

KEY TO

ABBREVIATIONS 1. Prob problems

2. Qual- qualities

3. Agg- aggression

4. Perf- performance

5. Edcn- education

6. Resp- responsibilities

7.

It was the first time after independence that Gandhi Jaynti was not a gazette off

day. It was heartening to see even celebrities join in the drive and take to streets in

order to clean their cities When one visits a country other than India, the first thing that one notices is the amount of cleanliness that is there on the roads. Here in

India, we dont think twice before littering our streets, schools, offices and even

homes. It was therefore very refreshing to see all people engaged in the task of cleaning their surroundings, especially on the birth anniversary of the father of the

Nation.

I would like to commend the efforts of the Prime Minister and other people who made this initiative a success. It is my humble request to all fellow Indians that

each day we should put efforts into maintaining clean surroundings. We must

continue to strive for a clean and prosperous nation.

Yours Truly Anandita Bose

6. The Simple Pleasures of Life F 1+ C 4 + E 5= 10 By Riya/Rakhsit

Life has become all about meeting deadlines, completing a project or an assignment

and fulfilling responsibilities. Of course, doing the said things is important but are

we not distancing ourselves from enjoying life to the fullest? When was the last time you sat with your family members and watched a good

movie? In the mad rush of todays fast-paced life, we are frantically trying to move

towards our goals, without sparing a thought about this wonderful journey called life. Simple pleasures like reading a good book, going out for a walk in the nearby

park, a simple conversation with an old friend, etc.are fast being replaced by text

messages on ones birthday, quick e-mails, mad working hours and detached personal life,

It is important to find time for out ownseles in our busy schedules. And theres no

better way than to go back to the simple ways of yore to make yourself and others around you happy.

Junk the Junk Food

By Shreya Today, junk food is like a fashion, people are getting addicted to it It is cheap and

available at every nook and corner of the city. Its easy availability is one of the

reasons of its increasing popularity.

Once in a while it is in line to go for such food but if we take such food daily, it will

lead to many health problems. In India every third man is suffering from obesity

which results in high blood pressure heart problems, diabetes, etc. Junk food generally contains transfats which make one obese, lousy and dull. The

unhygienic places where these products are made make it more unhealthy. This

food at times causes acidity and sleeplessness which bring energy levels down and the person feels lethargic.

Children should avoid junk food or try to rerduce its intake and instead eat healthy

food for proper growth. Schools can slso help develop healthy eating habits by banning junk food in their canteens and by setting marks for tiffins. Only healthy

young people can take a nation forward. So rat healthy and remain healthy.

7. F 1+ C 4 + E 5= 10

Good morning to the respected jury members, my dear opponents and all others present here Today, I stand before all of you to speak for the motion-Technology

Can Never Replace Teachers.

Teachers, unlike technology, do not leave us with just facts they establish a connection between the facts that we learn and our everyday lives, so that we can

apply the same to our daily dealings with people and surroundings. Further, a

computer or a smart phone con never give you the personal and human attention that teachers always do. That word of encouragement, that gesture of appreciation

better individuals.

Technology does help us in gaining knowledge but it is our teachers who help us assimilate and use that knowledge to our advantage. With this, I would rest my

case.

Thank you

Or Growing Violence among Children

By Rakhee

Across the various sections of society, adolescents are getting more and more violent. They are becoming impatient and as a result more violent in their approach.

They cannot tolerate a no for an answer and display their despondency by being

aggressive and turn violent at the slightest provocation. Who do we blame? Parents, school, society or the adolescents themselves. Parents

are too busy earning a living and believe that money can compensate for the

parental love and nurturing that their children are missing out on. Schools are buckling under the pressure of the new found psychological studies and

hence tend to overlook many of the apparently minor offences, which turn out to be

major stumbling blocks.

When things dont work their way, our young friends turn violent. This could be verbal or physical. It could be directed at the parents, a young sibling, authorities,

or public property. At times due to this aggressive attitude the child harms his

ownself. It is indeed a sad state of affairs that in the land of Gandhi, the rule of the day is

violence. It is time to do a reality check on the value system in our society. Parents

and schools should join hands and do everything possible o stop out adolescents from turning into a pack of brats. Only then can our nation progress and the future

can be a bright one envisioned by the youth of our country.

8. 1*4= 4 (i) The poet does not want us to speak in any language because he wants total

silence.

(ii) By not move our arms so much; the poet wants us to cease all physical

activity. (iii) The poet wants us to achieve a higher level mental activity by way of ceasing

all physical activity and quit introspection.

(iv) The word language signifies various religion and the different languages

spoken.

OR (i) The walls suggest the poor and ill-equipped environment of the slum school.

The sour cream walls of the school, which were probably painted with the help of

donations, further add to the pale and sad ambience of the poem. (ii) The walls of the classroom have a portrait of Shakespeare, open-handed

maps showing beautiful valleys, buildings and domes.

(iii) The poet thinks that the adornments on the walls of the classroom are in sharp contrast to the dull dreary atmosphere of the slum school. Shakespeare

stands for the study of classical literature, the word map represents the world

outside the classroom. The world of these children is full of monotony, dullness and

hopelessness which prevent them from experiencing any of these in reality. (iv) The lead sky refers to the dull and colourless world of the slum children.

9. 4*3= 12 (2 C + 2 E) each (a) Shakespeare becomes wicked and the map a bad example for the slum

children because both these things tempt them to steal by showing them a world

which they do not have access to and cannot be part of. (b) Douglas plans on going down till the bottom of the tiled pool, use all his

strength to hit the bottom of the pool as hard as he can and then come to the

surface of the water like a cork and paddli to the edge of the pool. He doesnt succeed as his legs become tense, his lungs are ready to burst and he comes up

slowly instead of like a cork

(c) The meaning of Saheb-e-Alams name is Lord of the universe Anees Jung

says if Saheb knew the meaning of his name, he would have a hard time believing it because in reality he is only a poor ragpicker.

(d) Jo was surprised to hear that roger Skunks mother hit the wizard and got

Roger to smell like his old self again. She wanted the wizard to hit the mother and let Roger Skunk retain the smell of roses so that he could play with his friends.

(e) The title The Rattrap is just and apt. It has been used metaphorically for

the world that we line in. All the riches and comforts of the world are like bait for us. As soon as we enter the trap to catch the bait, we got caught into it. The

peddler, after stealing the money felt himself trapped.

(f) Aunt Jennifer is embroidering tigers. The tigers signify the silent revolt against male-dominated society. Aunt Jennifer was suffering a lot due to the

pressure of married life while the tigers are proud and courageous.

10. C 3 + E 3 = 6 Indeed, the Champaran episode was not only a turning point in Gandhijis life, it

was also very curial to the slow and steady success of the Indian National Struggle.

It was after the Champaran episode that Gandhje decided to involve himself

completely with the Indian national struggle and remove the fear of the British from the minds and hearts of the deprived, poor Indians.

He began work at the ground level by improving health and sanitation, setting up a

primary school and making the exploited lot realize the values of self-reliance. Further, with the dissolution of the indigo-sharecropping arrangement, he made the

peasants realize that with truth, persistence and non-violence, they could achieve

anything. OR

Gandhis procedure to handle popular grievances finds limelight in the lesson in

question here. He follows the most scientific. Proves to redress popular grievances in Champaran. Like a good scientist, he first collects information, observes gravity of

the grievance through dedication of people to the cause, consults all concerned and

then experiments with popular mobilization. Finally, he meets the authority at the

helm and, thus, the grievance is gone for ever, Hand all politicians adopted this

procedure, people in India would have overcome almost all problems including

poverty, class and caste conflicts, etc.

11. C 3 + E 3 = 6

Dr. Sadao is faced with a moral and professional dilemma when the American

prisoner of war is washed ashore right outside his house. If he harbours him he might be arrested as a traitor but if he hands him over, his duty as a doctor, who

saves all life, would be compromised

He thus operates upon him and decides to hand him over once he recovers. He does inform the General about the soldier and since the General needs Dr. Sadaos skills

as a doctor to save his own life, he agrees to send assassins to take care of the

prisoner, while Dr. Sadao would be rendered safe and his reputation untarnished.

However, the General because of being self-absorbed, forgets to send assassins and that is when Dr. Sadao lets the prisoner flee to safety, In this way, he protects the

honour of his profession as well as his country.

OR The message given in the lesson is that nature laws are above all and saving the

life of a dying person is always much above the demarcated boundaries of countries

and nations. Here a doctor couple saves the life of an American war convict. Both of them endure gross criticism from their servants and they have to give a false report

to the officers in Japanese military. They are doctors and, therefore, complicance

with the professional code of conduct as per the Hipocrtic oathe is of paramount importance for them.

12. C 3 + E 3 = 6

Dr. kemp is a former associate of Griffin in his college days. Griffin had been a

student and knew kemp to be interested in aspects of science. It is to kemps house that Griffin goes, in his final attempt to find an accomplice and live a more normal

life.

A detached person from the very start, kemp usually keeps to himself, busy continuing with his own study in the hope of being admitted to the Royal Fellows

His own experiments and fascination with science enable him to listen sensibly to

griffin, but in spite of being rather contemptuous of his fellow citizens, his common sense and decency prevent him from being a part of Griffins schemes.

Kemp is also the only cool headed person in the town one the final attack begins.

He runs to escape Griffin, but as soon as Griffin catches him he has the presence of mind to turn the capture around. He is also the first to realize that Griffin is

invisible and injured; It is because of his report to the authorities that Griffin finally

meets his end.

13. C 3 + E 3 = 6 Mr. Marvel first realizes that hes being used for evil purposes by Griffin after the

incident at Iping he immediately decided on resigning, calling himself a miserable

and weak tool. However, for Griffin, even though hes a poor tool, hes the only tool in hand and he refuses to let go of him.

Marvel again tries to save himself at Port Stove by trying to get the mariner

understand his plight but even then Griffin handles him harshly and forces him to change his stance.

Finally, he gives Griffin a slip by running into the Jolly Cricketers Bar and this time,

after initial blows and hits, he finally manages to free himself of the influence of the invisible man.

(a) DeMorgtans Theorem states that

(i). X + Y = X . Y (ii). X . Y = X + Y

Proof: Assuming that DeMorgons laws are true. That means, all Boolean

laws should hold on it.

Let X + Y = P ---------------- (i)

Therefore given theorem (i) we get P = X . Y ---------------- (ii)

Since Boolean laws hold on it, Complementarity law should also hold on it.

P + P = 1 and P . P = 0

P + P = 1

Replacing values of P, we get

P + X . Y = 1

L.H.S. = (P + X) (P + Y) from (ii)

Replacing values of P, we get

(X + Y + X) (X + Y + Y) = (X + X + Y) (X + 1)

= (1 + Y) ( X + 1) (since X + X= Y + Y =1)

1 .1 = 1 = R. H. S. (since 1 + Y = 1 + X =1)

Similarly, replacing P and P in P . P = 0, we get

(X + Y) X . Y = 0

L.H S. = X X Y + Y X Y

0 + 0 = 0 = R.H.S. (since XX = 0 , YY =0)

Thus complementarity law fully hold on it
