When we look at a towering skyscraper, we are often amazed by its height and design. The part of the building that makes this possible, however, (35) __________ often overlooked because it is completely hidden from view. This essential component is the foundation, a complex structure buried deep in the earth. Its primary purpose is to provide a stable base that can support the immense weight of the entire building above it.

A skyscraper's foundation does a critically important job: it must safely (36) __________ the enormous weight of the building, known as its 'load', from the structure to the ground. This prevents the building from sinking. The foundation is located deep (37) __________ the ground's surface, distributing the load over a large area. If the soil directly under a building is not strong enough to support this pressure, the foundation must be designed to reach a stronger layer farther down.

For many modern skyscrapers, the soil near the surface is too soft to support such a heavy structure. (38) __________, engineers use a special type of deep foundation system, most commonly involving piles. Piles are long columns made of steel or reinforced concrete. These piles are driven deep into the earth until they reach bedrock, which is an extremely (39) __________ layer of rock capable of supporting massive loads.

The process of creating a pile foundation is precise. The piles are forced into the ground, sometimes hundreds of feet down, until they hit the solid rock layer (40) __________ the building can be securely anchored. During construction, (41) __________ pile is carefully tested to ensure it can support its designated share of the load. This ensures that the entire foundation system works together as one solid unit, creating a stable platform for the skyscraper.

In conclusion, the foundation is the unsung hero of any skyscraper. By transferring the building's massive weight onto solid bedrock far below the surface, it serves two main purposes. It is designed to (42) __________ the skyscraper from sinking or leaning over time, and it anchors the tall structure firmly to the ground, allowing it to withstand forces like strong winds and earthquakes. Without a strong and stable foundation, these architectural marvels could not exist.

For many teenagers in Vietnam, the high school entrance exam, or Kỳ thi tuyển sinh lớp 10, is one of the most stressful events in their academic lives. The competition is intense, and the pressure to secure a place in a good high school is enormous. In recent years, a new generation of study aids has emerged: AI-powered tutors. Companies like HOCMAI are using artificial intelligence to help students prepare. But can these digital platforms truly offer an advantage in such a high-stakes environment?

At its core, an AI tutor works by creating a deeply personalized learning experience. Unlike a traditional textbook that presents the same information to everyone, an AI platform first analyzes a student's performance on practice questions and diagnostic tests. It identifies specific areas of strength and weakness. Based on this data, the system generates a unique study plan. For example, if a student struggles with geometry but excels at algebra, the AI will provide more geometry problems and review materials, allowing the student to focus their effort precisely where it is needed most.

The benefits of this approach are significant. Firstly, it promotes efficiency. Students no longer waste valuable time reviewing topics they have already mastered. Secondly, these platforms offer incredible flexibility; a student can study at midnight or on a bus, as long as they have a device and internet connection. Perhaps most importantly, AI tutors provide instant feedback. When students make a mistake, the system can immediately explain what they did wrong, allowing for rapid correction and learning. This continuous loop of practice and immediate feedback is a powerful tool for building confidence and skill.

However, AI tutors are not a perfect solution and have clear limitations. They lack the human touch of a real teacher. An AI cannot provide the emotional support or encouragement a student might need when feeling discouraged or overwhelmed. Furthermore, there is a risk of over-reliance. Students must still possess self-discipline to follow their study plan without a teacher's direct supervision. Finally, there is a practical barrier: access to a stable internet connection and a suitable device is necessary, which may not be available to every student.

In conclusion, AI tutors should be viewed as powerful supplements, not substitutes for traditional learning. They offer a data-driven, efficient way to prepare for exams, but they cannot replace the role of a dedicated teacher or the importance of a student's own hard work and motivation. The students most likely to succeed will be those who intelligently combine the focused practice offered by AI with the guidance and support they receive from their teachers and their own consistent effort.
