SECTION A – READING (30 Marks )

Read the following passage carefully. (12 Marks)

1. Many of us believe that "small" means "insignificant". We believe that small actions and choices do not have much impact on our lives. We think that it is only the big things, the big actions and the big decisions that really count. But when you look at the lives of all great people, you will see that they built their character through small decisions, small choices and small actions that they performed every day. They transformed their lives through a step-by-step or dayby-day approach. They nurtured and nourished their good habits and chipped away at their bad habits, one step at a time. It was their small day-to-day decisions that added up to make tremendous difference in the long run. Indeed, in matters of personal growth and character building, there is no such thing as an overnight success.

2. Growth always occurs through a sequential series of stages. There is an organic process to growth. When we look at children growing up, we can see this process at work: the child first learns to crawl, then to stand and walk, and finally to run. The same is true in the natural world. The soil must first be tilled, and then the seed must be sowed. Next, it must be nurtured with enough water and sunlight, and only then will it grow, bear fruit and finally ripen and be ready to eat.

3. Gandhi understood this organic process and used this universal law of nature to his benefit. Gandhi grew in small ways, in his day-to-day affairs. He did not wake up one day and find himself to be the "Mahatma". In fact, there was nothing much in his early life that showed signs of greatness. But from his midtwenties onwards, he deliberately and consistently attempted to change himself, reform himself and grow in some small way every day. Day by day, hour by  hour, he risked failure, experimented and learnt from mistakes. In small and large situations alike, he took up rather than avoid responsibility.

4. People have always marvelled at the effortless way in which Gandhi could accomplish the most difficult tasks. He displayed great deal of self-mastery and discipline that was amazing. These things did not come easily to him. Years of practice and disciplined training went into making his successes possible. Very few saw his struggles, fears, doubts and anxieties, or his inner efforts to overcome them. They saw the victory, but not the struggle.

SECTION A- Reading Comprehension (20 Marks)

Q1. Read the following passage and answer the questions that follow:

(7 marks)

For bizarre items floating in the ocean, try topping this: The upper half of a set of false teeth, seen bobbing around in the South China Sea.

"I remember thinking: 'How on earth did it get there?"' said Lindsay Porter, a marine scientist.

The teeth, gripped in their plastic gums, are part of the millions of tons of plastic trash that somehow ends up in oceans around the world every year. Mostly, it is more mundane stuff, the flotsam and jetsam of everyday life: picnic plates, bottles, cigarette lighters, toys, spoons, flip-flops etc.

Taken together, the virtually indestructible mass is now so large that it is causing environmentalists, government officials and the plastics industry itself to sit up and take note. Many scientists believe marine plastic pollution is one of the major issues — along with climate change — facing the planet.

The problem is not the plastic itself: Even those who lobby against plastic pollution acknowledge that plastic materials help combat climate change, for example by reducing the weight — and thus fuel consumption — of vehicles, or by helping to insulate buildings.

Most of that ends up in landfills. Some is recycled. But a significant amount ends up in the sea, swept there via rivers or sewage drains, discarded on beaches or dumped from ships. Exact figures are hard to come by, but some researchers estimate that 4.7 million tons reaches the sea each year, according to Plastic Oceans, a London-based charity that has enlisted numerous scientists to create a full-length documentary film on the topic.

Bear in mind that this stuff does not just biodegrade like food waste, wood or paper. Scientists believe it takes decades, if not centuries, for most types of plastic to degrade. That means virtually all the plastic material that has ever ended up in the ocean is still out there.

"When a plastic crate or bottle floats around in the ocean, it does not biodegrade. It only breaks into smaller and smaller pieces — which are still plastic," said Peter Kershaw of the British marine science center Cefas, who helps advise the United Nations on marine environmental protection issues.

Some of the debris sinks to the ocean floor. Some washes back onto land, sometimes in remote and once-pristine parts of the world.

But most is gradually swept up by ocean currents, which have assembled the assorted mess into five "gyres," or garbage patches, in the Pacific, Atlantic and Indian oceans.

Do not imagine these to be vast, tangible floating islands of trash that you can walk across. Yes, there are visible chunks of debris — some large enough to trap or choke wildlife.

Mostly, however, the plastic soup consists of tiny fragments, some the size of a fingernail, some much smaller, floating on or below the surface across thousands of kilometers.
