Read the following passage and mark the letter A, B, C, or D to indicate the answer to each of the question.

Since the first Paralympic Games in Rome in 1960, swimming has been one of its main sports. The thrill of competition aside, swimming offers many benefits including strengthening the cardiovascular systems and the major muscle groups of both the upper and lower body. It also develops flexibility in the muscles and joints as the swimmer performs a wide range of motion against the water's resistance. It is an activity that keeps your heart rate up but takes some of the stress that is common in impact sports off the body; injuries don't occur as easily. The water's buoyancy evenly distributes and supports the weight of the body; there is no danger of falling, and there are no impact forces on the

residual limb. Swimmers who have disabilities endorse the sport because it gives them a sense of freedom. They don't have to rely on any supportive device, such as a wheelchair, to assist them. They are independent. They are only judged on their times and whether those times are dropping. “Water is one of the big equalizers,” said Queenie Nichols, long-time Paralympic swim coach. "One of the phrases I heard since I got involved in this is that we are all equal in the water and that is really true. Athletes with disabilities, from below-knee amputations to severe quads, can compete and compete successfully.”

While it is not essential to begin swimming at an early age to become an elite athlete, Nichols believes that the sooner an individual becomes comfortable in the water, the better. "I think starting at about 5 years old is a good age to get children involved, in the pool at least once a week. Keep it fun for them until they show an interest in growing with a Club," she said.

“Most clubs that belong to USA Swimming or YMCAs offer coaching and training at the appropriate level for age and experience,” Nichols said. "We suggest aspiring athletes participate with an able-bodied club at first because of the greater number of individuals they will compete with."

Typically, swimmers in this introductory/ foundation phase, usually aged 5 to 8 or 9, remain there for about 5 years before transitioning to the next level, which includes more advanced drills and stroke efficiency. Athletes with disabilities who join swimming clubs benefit from better sport-specific coaching, more rigorous training, more competition in practice, and higher expectations than they are likely to receive in other settings. Other benefits include socialization opportunities, greater independence in activities of daily living, and improved ability to cope with limitations imposed by disabilities.

As mentioned in paragraph 4, Athletes with disabilities who join swimming

clubs can benefit _____.

Which of the following could be the best title of the passage?

Read the following passage and mark the letter A, B, C, or D to indicate the answer to each of the question.

Since the early eighties, we have been only too aware of the devastating effects of large-scale environmental pollution. Such pollution is generally the result of poor government planning in many developing nations or the shortsighted, selfish policies of the already industrialized countries, which encourage a minority of the world’s population to squander the majority of its natural resources.

While events such as the deforestation of the Amazon jungle or the nuclear disaster in Chernobyl continue to receive high media exposure, as do acts of environmental sabotage, it must be remembered that not all pollution is on this grand scale. A large proportion of the world's pollution has its source much closer to home. The recent spillage of crude oil from an oil tanker accidentally discharging its cargo straight into Sydney not only caused serious damage to the harbor foreshores but also created severely toxic fumes which hung over the suburbs for days and left the angry residents wondering how such a

disaster could have been allowed to happen.

Avoiding pollution can be a fulltime job. Try not to inhale traffic fumes; keep away from Chemical plants and building-sites; wear a mask when cycling. It is enough to make you want to stay at home. But that, according to a growing body of scientific evidence, would also be a bad idea. Research shows that levels of pollutants such as hazardous gases, particulate matter and other chemical 'nasties’ are usually higher indoors than out, even in the most polluted cities. Since the average American spends 18 hours indoors for every hour outside, it looks as though many environmentalists may be attacking the wrong target.

The word "nasties" in paragraph 3 means _____.
