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.

Loại mạch dẫn nào làm nhiệm vụ dẫn nước và muối khoáng từ rễ lên lá?

Cỏ dại quen nắng mưa

Làm sao mà giết được

Tới mùa nước dâng

Cỏ thường ngập trước

Sau ngày nước rút

Cỏ mọc đầu tiên…

Trong cuộc đời bình yên tựa nghìn xưa

Gần gũi nhất vẫn là cây lúa

Trưa nắng khát ước về vườn quả

Lúc xa nhà nhớ một dáng mây

Một dòng sông, ngọn núi, rừng cây

Một làn khói, một mùi hương trong gió…

Có mấy ai nhớ về ngọn cỏ

Mọc vô tình trên lối ta đi

Dẫu nhỏ nhoi không đáng nhớ làm chi

Không nghĩ đến nhưng mà vẫn có.

Read the passage 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.

We seem to be entering a boom era for greenwashing - the tactic of covering routine pollution in eco-friendly language. [I] Picture running a high-emitting corporation: meaningful decarbonisation would demand painful negotiations, huge capital outlays, and a full redesign of the business model. Hiring an expert agency to splash "carbon- neutral" or "net-zero" across products is far easier, buying time while emissions remain untouched.

Consumers meet this sleight of hand everywhere. Airlines sell "carbon-neutral" flights, filling stations boast about "net-zero" fuel, and breakfast bacon is re-labelled as planet-safe. Advertising spin is old, yet today it is manipulated to conceal ongoing environmental damage. Social media influencers and glossy sustainability reports amplify these claims, broadcasting the narrative far beyond traditional marketing channels.

The term greenwashing emerged in the 1980s, an era of oil spills and growing climate science, but the practice has exploded only recently. [II] Intensifying public anxiety over global heating and ecosystem collapse has placed companies under sharp scrutiny; many boards therefore choose eye-catching PR over the tougher route of restructuring supply chains, energy sources, and product lines. Regulators on both sides of the Atlantic are struggling to police false eco-claims, yet enforcement still lags behind corporate ingenuity. Investors, eager to protect short-term returns, frequently applaud these surface-level initiatives, reinforcing the cycle. [III] No sector illustrates the issue better than oil and gas. Having realised that denying climate science now backfires, the industry has swapped denial for "green" paint. Press releases trumpet potential renewable ventures while drilling plans expand unabated.

Why does this matter? Greenwashing and climate denial share a core objective: to postpone the deep emission cuts claimed by scientists as urgent this decade. [IV] Whereas denial disputes the crisis, greenwashing misleads the public into believing problems are solved, thereby eroding consumer advocacy of genuine environmental actions and stalling regulatory reforms. In effect, it acts as a soothing lullaby, guiding society ever closer to ecological breakdown while fostering a false sense of progress. Exposing the facade-and insisting on verifiable, measurable carbon reductions-is essential if rhetoric is to give way to real action.
