Mars, the fourth planet from the Sun, is often called the 'Red Planet'. This nickname is not a poetic invention but a direct description of its appearance. For millennia, its distinct reddish color has set it apart from other celestial bodies in the night sky. It has long been a source of fascination, (35) __________ the curiosity of astronomers and sky-gazers for centuries. So, what makes Mars so red?

The answer lies in its soil. The surface of Mars is covered in a fine dust that is rich in a chemical compound called iron oxide. This single compound (36) __________ a crucial role in the planet's appearance. If the name 'iron oxide' sounds scientific, its common name is much more familiar: rust. From space, the reddish hue is so strong that it (37) __________ be seen even without a telescope.

Scientists believe that billions of years ago, when Mars had active volcanoes, large amounts of iron were released onto the surface. Over time, this iron reacted with small amounts of oxygen in the atmosphere, causing it to rust. (38) __________ is the same basic chemical process that happens to metal left outside on Earth. The resulting Martian soil is therefore much (39) __________ in iron than typical Earth soil.

The redness is not limited to the ground. Mars experiences powerful winds that create enormous dust storms. (40) __________ does the surface appear red, but the atmosphere is also affected. The fine, rust-colored particles are swept up into the thin Martian air, giving the sky a pink or light red color. These dust storms can be so (41) __________ that they cover the entire planet for weeks.

(42) __________, the mystery of the Red Planet isn't a mystery at all. It is not due to strange alien life or magical properties.

In today's world, fashion is about much more than just the latest trends. A growing movement called 'ethical fashion' is encouraging consumers, especially young people, to think more deeply about the clothes they wear. It's not just about looking good; it's about doing good. People are asking important questions: Where do my clothes come from? Who made them? Does my purchase support something positive? This shift in thinking suggests that even a simple item, like a t-shirt, can carry a powerful message and make a real difference in the world.

A shining example of this philosophy in Vietnam is Tòhe, a social enterprise that was launched with a simple yet powerful idea. Tòhe takes the imaginative and colorful artwork created by children with special needs, including those with autism, and prints these unique designs onto a wide range of products like t-shirts, bags, and notebooks. The goal is to create beautiful, high-quality items that not only appeal to customers but also tell a meaningful story about the creativity of disadvantaged children.

The business model of Tòhe is designed for direct social impact. The company organizes free creative art classes, providing a safe and encouraging space for children to express themselves through painting and drawing. When a product featuring a child's artwork is sold, 5% of the revenue is paid directly to that young artist, offering them a small but significant income. The remaining profit is not taken by owners but is reinvested back into the enterprise. It is used to fund more art classes, buy materials, and expand the project to reach more children across the country.

The benefits for the children involved with Tòhe extend far beyond financial gain. These art classes and the recognition they receive provide a vital platform for them to communicate their feelings and perspectives. Seeing their art on a popular product boosts their confidence and fosters a strong sense of self-worth. Furthermore, Tòhe's work helps to change the public's perception of what people with disabilities are capable of achieving, showcasing their incredible talent and unique viewpoints.

Ultimately, the story of Tòhe demonstrates that young consumers have power. The choice to buy a Tòhe t-shirt over another brand is a conscious decision. It is a statement that you value creativity, support inclusivity, and believe in a business model that prioritizes people over profit. It proves that a single purchase, a single t-shirt, can indeed contribute to changing a life for the better, turning fashion into a force for good.
