Have you ever wondered how a digital thermometer works so quickly? It’s not magic; it’s technology! The secret lies in a special sensor called a thermistor, a resistor whose electrical resistance changes significantly with temperature. When you place the thermometer under your tongue, the thermistor begins (25) __________ up. As its temperature rises, its electrical resistance decreases. The (26) __________ the temperature, the lower the resistance. (27) __________ allows the thermometer's microchip to perform a quick (28) __________. The chip measures the resistance and uses a pre-programmed formula to convert it into an exact temperature reading, which is then displayed on the screen. So, the next time you're feeling unwell, remember it is the tiny thermistor that helps (29) __________ track of your health.

For many teenagers, leather goods like sneakers, bags, and jackets are key fashion items. However, the production of traditional animal leather raises ethical questions about animal welfare and has a significant environmental impact. In response, science is offering a revolutionary alternative: lab-grown leather. This new material is gaining attention, especially among young consumers who want their style choices to also be responsible choices, blending fashion with a conscience.

So, how is this 'bio-leather' made? Instead of coming from animals, it is grown using biotechnology. One of the most promising methods involves using mycelium, which is the root structure of mushrooms. These roots can be grown into a solid mat that looks and feels very much like leather. Another innovative process uses engineered yeast to produce collagen, the same protein that makes up animal skin. This collagen is then formed into a leather-like material.

The advantages of bio-leather are clear. It is cruelty-free, meaning no animals are harmed. Its production also typically uses less water and fewer harmful chemicals than traditional leather tanning. However, the technology is not without its challenges. Currently, production costs are high, and scaling up to meet global demand is a major hurdle. Convincing a market accustomed to traditional leather to adopt this new material is also not a minor task.

While countries like Vietnam have a large and established leather and footwear industry that still relies on conventional animal hides, local innovators and fashion brands are watching these global developments closely. They see the potential for a more sustainable future. As this technology improves and becomes more affordable, bio-leather could transform the fashion industry, offering a future where the accessories we love are both stylish and kind to the planet.

In recent years, the popularity of plant-based diets has soared, with more people choosing to reduce their meat consumption for health, ethical, and environmental reasons.

A significant concern is the rise of highly-processed vegan 'junk food', (37) __________.

While these products can make the transition to a plant-based diet easier, (38) __________. Many health experts now advise consumers to be mindful, (39) __________.

Ultimately, a healthy vegan diet focuses on balance, (40) __________.

A. relying on them too heavily can undermine the health benefits associated with whole-food veganism

B. ensuring that convenience does not come at the expense of nutritional quality

C. which often contains high levels of salt, sugar, and unhealthy fats to mimic the taste of meat

D. urging them to read nutritional labels carefully and prioritize whole foods like fruits and vegetables
