2. Write the summary of the passage in your own words. 3 marks
It was bound in a rough, red cloth, now smoothened in places with the many caresses it had
received over the years. Its name boldly etched in gold over its hard cover. Its spine still holding on
firmly to the age old pages, much thumbed, dog-eared, yellowing pages.in its illustrations,
lithographs by the author himself, and a frayed red ribbon placed between the pages I had read the
last time. This is my favourite book.
That book startled me off on a journey that inevitably took me to the book alleys that still make the
three hundred year old city proud. The fact that my lane meandered through several by-lanes and
reached the book alleys in less than fifteen minutes made my trips frequent and my pocket-money
meagre. The narrow lanes were lined with small shops with dusty shelves. Their bespectacled shop-
owners – bibliophiles in their own right – were always eager to help me find treasures in all shapes
and sizes, bound in cloth or leather, some new and some which had changed several hands; others
which had corners folded, many in tatters, a few boasting of an autograph or a note written in
attention of a loving reader. My prized possession in those days was a book called Sita that was
illustrated with paintings by the illustrious Raja Ravi Verma.
Nothing gave me more pleasure than the feel of a cold spine against my palm, the weight of the
pages, their slight reluctance to open spontaneously, the faint crick at the turn of each page, and the
musty smell of the yellowing pages mixed with a slight whiff of the jet-black ink that filled my nostrils
as I brought the book close to my face.
Thus enamoured by books of all shapes and sizes, colours and textures and thus pampered by the
abundance of such gems in dusty attics and tiny shop windows, i stepped out of my city's
boundaries and stepped into different cities. As a resident in some, whilst a tourist in others. My
experiences in each of those cities have ben varied as have been my encounter with books.
In the beginning, I would wait to return from those cities and visit the old, familiar book alleys for my
ration of books for the rest of the year. But soon I realized that the character of the alleys, the shops
lining them and the books they sold had started to change. The old, dusty spines of ageless classics
were fast being replaced by Last Minute Suggestions for Board Examinations, Queries & Answers
Made Easy, cheap reprints of old classics, poor translations of world famous children's classics and
photocopies of what were otherwise intellectual masterpieces. Makeshift shops had encroached
upon the pavements of the narrow alleys and had started to threaten the original inhabitants
themselves. Disappointment was inevitable, and it didn't take too long to set in. Like many others, I
soon decided it was time to park my hopes elsewhere.

Q2. 1. On the basis of your reading make notes on the below passage. 5 marks
2. Write the summary of the passage in your own words. 3 marks
A boss who enjoys sycophancy is not a leader. Inspired leaders don’t encourage servile behaviour, they confront people with their freedom. That was the provocative message from Peter Block, consultant and bestselling author of influential books like, Flawless Consulting, Stewardship, The Empowered Manager and Community. ‘To say, “I want my boss to be like my mommy”. The notion that leaders know and others don’t is a myth, said Block. The management guru said people should stop treating bosses as if they are – just bosses. “People are responsible for how they are inside the institution. Subordinates create the bosses that they have. Maybe the audience creates the performance. Maybe the listening creates the speaking. Maybe citizens create leaders, maybe employees create bosses, maybe students create teachers and children create parents”, he said. Block added that change management is often important because it treats leaders as if they are important, when they aren’t.” Don’t go to the boardroom. Conventional leaders only know what is working somewhere else. Go to the fringes and the middle. That’s where all leadership exists. That’s where the real engagement should be. Part of the challenge is to create conversations. A great question if you are interested in change or development is this: What is the conversation that we haven’t had?” he said. Arun Maira, former Chairman, Boston Consulting Group and now Member, Planning Commission, concurred. “Leadership is not about imposing one’s position and authority on others. It is about the art of coaching without having direct authority”, he said. According to Maira, there is a strong need to create a leadership culture where nobody is the boss but people collaborate in an environment of collective ability and responsibility to improve the world. “A leader is not necessarily a person in a position of authority but someone who takes the first steps towards something they truly believe in,” he said. Tata Steel V.C., Muthuraman pointed out that leadership programmes focus on left brain learning in areas like finance, marketing organization structures and strategy. “As much as 70%-80%- of a person is their intrinsic qualities. We are doing something wrong by sending out programmed robots to the world instead of nurturing qualities like compassion, conviction, ethics and courage against all odds. Including, telling the truth,” he told the audience at the School of Inspired Leadership. Space for making notes:
