When we think of architectural wonders, the dome often comes to mind. It's an elegant solution for covering a vast area without the need for internal columns, creating an open, impressive space. The genius of a dome lies in its ability to redirect weight. Instead of pushing all the force straight down, it spreads the load outwards along its curved surface. (25) __________ makes it possible to build enormous interiors that feel light and airy.

The Pantheon in Rome is perhaps the (26) __________ example of this principle. Built almost 2,000 years ago, its concrete dome is still the world's largest unreinforced one. Its (27) __________ construction has inspired countless architects throughout history. Roman engineers managed to achieve this by using lighter materials towards the top of the dome, a clever technique that reduced stress. They also avoided (28) __________ heavy support pillars inside, which was revolutionary. The structure has truly managed to (29) __________ the test of time.

Genetically modified (GM) foods are created by changing the DNA of plants or animals to give them new, desirable traits. This technology is at the center of a global debate, with strong opinions on both sides. Supporters see it as a scientific breakthrough that can solve major world problems, while critics worry about the long-term consequences. This discussion is becoming increasingly relevant in many countries, including Vietnam.

The primary argument for GM crops is their ability to increase food production. In Vietnam, for example, the government has approved GM corn varieties that are engineered to resist pests. This means farmers can have larger harvests and use fewer chemical pesticides. Proponents say that because these crops are more resilient and produce more food, they can help ensure food security and improve the livelihoods of farmers by increasing their income.

However, there are also significant concerns. Critics question the long-term safety of eating GM foods, suggesting more research is needed to understand their effects on human health. There are also environmental worries, such as the potential for GM crops to cross-pollinate with wild plants, which could disrupt local ecosystems. These unanswered questions make some consumers and scientists cautious about fully embracing GM technology.

As a young person, the food on your plate, from corn chips to products with corn syrup, may contain ingredients from GM crops. The conversation about GM foods is not simple; it involves complex science, economics, and ethics. Understanding the different viewpoints is the first step towards forming your own informed opinion about what you choose to eat and the future of our food supply.

Reforestation, the act of planting trees, is often seen as a simple solution to climate change. However, a common approach has a major flaw: planting only one type of tree, known as a monoculture. This method seems efficient, but it creates fragile ecosystems. For instance, a single disease or pest can wipe out an entire forest, (37) __________.

Furthermore, these single-species forests lack the rich biodiversity needed for a healthy environment. They do not support the variety of insects, birds, and animals (38) __________. A true forest is a complex system, not just a collection of trees. Therefore, successful reforestation must imitate nature's own complexity, (39) __________. This approach ensures the new forest is resilient and sustainable for the future, (40) __________.

A. that a natural, mixed forest would attract

B. making it a true benefit to the planet

C. leaving the land barren and unable to recover quickly

D. promoting a diverse mix of native species
