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.

Read the following passage about climate change 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.

           Climate change refers to the long-term alteration of temperature and typical weather patterns in a place. This phenomenon is largely driven by human activities, particularly the burning of fossil fuels such as coal, oil, and gas, which increase the concentration of greenhouse gases in the atmosphere. They trap heat from the sun, leading to global warming and causing severe weather events, such as hurricanes, floods, and droughts, to become more frequent and intense. Climate change impacts nearly every region of the world and affects the natural environment, economies, and human health.

           As temperatures rise, polar ice caps and glaciers are melting at alarming rates, contributing to rising sea levels. Coastal regions face an increased risk of flooding, and many low-lying islands are at risk of disappearing entirely. Additionally, higher temperatures lead to the warming of oceans, affecting marine ecosystems and causing coral bleaching, which threatens biodiversity and the livelihoods of millions of people who depend on fishing.

            [I] The consequences of climate change are not just environmental; they also affect human society in significant ways. [II] Changes in weather patterns disrupt agriculture, leading to crop failures and food shortages in vulnerable regions. [III] Furthermore, climate change is linked to health issues such as respiratory diseases, heat strokes, and the spread of diseases carried by insects, like malaria and dengue fever. [IV]

           To combat climate change, a coordinated global effort is necessary. Governments, organizations, and individuals all have roles to play in reducing greenhouse gas emissions and promoting sustainable practices. Shifting to renewable energy sources, such as wind, solar, and hydropower, is essential. Additionally, conserving forests and investing in technology that captures carbon dioxide from the atmosphere can help mitigate the effects of climate change and pave the way for a healthier planet.
