Have you ever wondered why ocean tides (25) __________ and fall every day? This amazing natural phenomenon is mainly caused by the gravitational pull of the Moon. As the Earth rotates, the Moon's gravity pulls on the water, creating 'bulges' on the side of the Earth closest to it and on the opposite side. The Sun also has a gravitational effect on our oceans, but it's much weaker because it's so far away.

When the Sun, Moon, and Earth align, their gravitational forces combine to create very high and very low tides. (26) __________, when the Moon and Sun are at right angles to each other relative to the Earth, their forces partially (27) __________ each other out, leading to weaker tides called 'neap tides'. This gravitational dance happens without fail. In fact, if the Moon disappeared, our planet's tides (28) __________ be much smaller and less regular. (29) __________ coastal ecosystem depends on this predictable cycle. Life in tidal pools, for instance, is specially adapted to the changing water levels (30) __________ these areas.

The Fields Medal is often called the 'Nobel Prize of Mathematics.' Awarded only once every four years, it is the highest honor a mathematician under the age of 40 can receive. Winning this medal is not just a personal victory; it is a global recognition of extraordinary talent and groundbreaking work that pushes the boundaries of human knowledge. It represents the very peak of intellectual achievement in the field.

In 2010, Vietnam celebrated a historic moment when Professor Ngô Bảo Châu was awarded the Fields Medal. This was a significant achievement, earning him recognition for his proof of a complex mathematical idea called the Fundamental Lemma. The news, widely reported by media like Dân Trí, filled the nation with immense pride and showed the world the brilliant potential of Vietnamese minds on the global stage.

What does it take to reach such heights? While genius-level intelligence is necessary, it is not enough. The journey requires immense dedication and perseverance to overcome difficult challenges. Furthermore, modern mathematical breakthroughs are rarely a solitary effort; they often depend on collaboration with other bright minds. These personal qualities are just as important as the ability to work with complex numbers and theories.

Professor Châu's success has had a powerful effect, particularly on Vietnam's youth. His story serves as a profound inspiration, demonstrating that with hard work and passion, they too can compete and excel at the highest international levels. It encourages a new generation to pursue academic excellence in fields like science and technology, proving that a Vietnamese name can stand among the world's greatest thinkers.

Recycling is often presented as a simple solution to our waste problem. However, a phenomenon known as "wishcycling"—the tendency to recycle items hoping they are recyclable—often complicates the process. This good intention can paradoxically lead to more waste. (37) __________, the entire batch may be sent to a landfill. This happens because separating contaminated materials is too expensive for many facilities.

Furthermore, there's a psychological trap. Some people believe that because they recycle, they can consume more disposable products. (38) __________. Therefore, the focus should shift from just recycling to the more important "R's": reduce and reuse. Simply put, (39) __________ is far more effective than trying to manage it afterwards. (40) __________.

A. This mindset essentially cancels out the benefits of recycling

B. We must become more mindful consumers to truly make a difference

C. When non-recyclable items contaminate a batch of recyclables

D. creating less waste in the first place
