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.

Read the following passage about the urban shift 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 31 to 40. (2,5 points)

            [I] Water is one of the most essential resources on our planet, vital for all forms of life. However, increasing demand and pollution are putting immense pressure on our freshwater supplies. [II] According to recent studies, nearly 2 billion people worldwide live in countries experiencing high water stress, leading to a decline in the availability of this precious resource. This situation not only affects drinking water but also agriculture, sanitation, and energy production.

            The primary causes of water scarcity include population growth, urbanization, and climate change. As cities expand, the demand for water increases significantly. Moreover, agricultural practices that rely heavily on water are becoming unsustainable in many regions. Climate change further exacerbates these issues, causing unpredictable weather patterns and extreme droughts, which reduce water availability.

           [III] In response to this growing crisis, everyone must prioritize water conservation. Simple actions, such as fixing leaks, using water-efficient appliances, and practicing mindful consumption, can make a significant difference. Additionally, implementing policies that promote sustainable water management and investing in technologies for water recycling can help mitigate the impacts of water scarcity. [IV]

            Despite these efforts, the challenges remain substantial. It is crucial that we recognize the importance of conserving water and take immediate steps to protect this vital resource for future generations.
