Read the following passage about The Benefits of Outdoor Activities and mark the letter A, B, C or D on your answer sheet to indicate the best answer to each of the following questions from 23 to 30.
Engaging in outdoor activities has become increasingly popular in recent years. Not only do these activities provide an escape from the daily grind of life, but they also offer numerous physical and mental health benefits. Hiking, cycling, and team sports are just a few examples of outdoor activities that can enhance well-being.
First and foremost, outdoor activities encourage physical fitness. Regular participation in activities like hiking or cycling helps individuals maintain a healthy weight and improve cardiovascular health. The fresh air and natural surroundings can make exercising feel less like a chore and more like an enjoyable experience. Furthermore, studies have shown that spending time in nature can reduce stress levels and promote a sense of tranquility.
In addition to physical benefits, outdoor activities foster social connections. Participating in team sports or group hikes allows individuals to meet new people and strengthen existing relationships. The shared experience of overcoming challenges together can build camaraderie and enhance teamwork skills.
However, some people might argue that outdoor activities are not accessible to everyone. For instance, individuals living in urban areas may find it difficult to access green spaces or safe paths for cycling. This raises the question of equity in accessing outdoor resources.
Despite these challenges, the advantages of engaging in outdoor activities far outweigh the drawbacks. Those who participate regularly often report feeling happier and more fulfilled. The sense of achievement that comes from completing a challenging hike or mastering a new cycling route can significantly boost self-esteem.
In conclusion, outdoor activities play a crucial role in promoting both physical health and social well-being. By stepping outside and embracing nature, individuals can improve their quality of life. As we continue to navigate the complexities of modern living, it is vital to prioritize these enriching experiences.

Read the following passage about human life expectancy and mark the letter A, B, C or D on your answer sheet to indicate the best answer to each of the following questions from 23 to 30.
How long will a baby born today live? 100 years? 120 years? Scientists are studying genes that could mean long life for us all.
There are already many, many people who have passed the landmark age of 100. In fact, there are now so many healthy, elderly people that there’s a name for them: the wellderly. These are people over the age of eighty who have no major illnesses, such as high blood pressure, heart disease or diabetes.
There are many scientific studies of communities where healthy old age is typical. These include places like Calabria in southern Italy and the island of Okinawa in Japan. In Calabria, the small village of Molochio has about 2,000 inhabitants. And of these, there are at least eight people over a hundred years old. When researchers ask people like this the secret of their long life, the answer is almost always about food and is almost always the same: ‘I eat a lot of fruit and vegetables.’ ‘I eat a little bit of everything.’ ‘I neither smoke nor drink.’
In the past, scientists looked at things such as diet and lifestyle for an explanation of long life, but these days they are also looking at genetics. Researcher Eric Topol says that there must be genes that explain why people are protected from the effects of aging process. The new research into long life did scrutinize groups of people who have a genetic connection. One interesting group lives in Ecuador. In one area of the country there are a number of people with the same genetic condition. It’s called Laron syndrome. These people don’t grow very tall – just over one metre. But Laron syndrome also give them protection against cancer and diabetes. As a result, they live longer than other people in their families. Meanwhile, on the Hawaiian island of Oahu, there’s another group of long-lived men, Japanese-Americans. They have a similar gene to the Laron syndrome group.
Back in Calabria, researchers constructed the family trees of the 100-year-old people. They looked at family information from the 19th century to today. It is concluded that there are genetic factors that give health benefits to the men. This is a surprising result because generally in Europe, women live longer than men. So what really makes people live longer? It seems likely that it is an interaction of genes, the environment and probably a third factor – luck.
