(23) __________ The primary difference lies in how they are processed and the nutrients they retain. (24) __________

The Earth's surface isn't one solid piece. It is made of several giant puzzle pieces called tectonic plates. For millions of years, these plates (25) __________ very slowly, floating on the semi-solid mantle beneath. The places where these plates meet are known as fault lines. This constant movement can cause enormous pressure to (26) __________ along these faults.

When this pressure becomes too great, the rocks suddenly break and shift. This rapid movement releases a huge amount of energy in the form of seismic waves. This energy is the reason for the shaking (27) __________ we feel during an earthquake. The point underground where the rock first breaks is the focus, and the point on the surface directly above it is the epicenter. (28) __________, the most intense shaking is usually felt near the epicenter. The power of an earthquake (29) __________ using the Richter scale. Each level on this scale represents a tenfold increase in the quake's measured (30) __________. Major earthquakes can be incredibly destructive.

Most of us are familiar with the sounds of city life: the rumble of traffic, the buzz of construction, and the announcements from loudspeakers. While these sounds may seem like a normal part of the urban landscape, they can combine to create a serious, invisible threat known as noise pollution. In bustling Vietnamese cities, this is a daily reality for millions, affecting their quality of life in ways they may not even realize.

The health consequences of prolonged exposure to noise are significant. The constant auditory stress can disrupt sleep patterns, increase blood pressure, and lead to chronic stress. For teenagers, this is particularly damaging. The noise you hear on your way to school or in your neighborhood can directly affect your ability to concentrate on your studies and retain information, making learning more difficult and stressful.

Recognizing this issue, authorities have tried to address specific problems. For example, the excessive use of vehicle horns is a common complaint. To combat this, Vietnamese regulations, such as Decree 100, have been introduced to penalize drivers who misuse their horns. However, enforcing these rules in crowded urban environments remains a considerable challenge, requiring both official action and a change in public awareness.

Ultimately, tackling noise pollution is a shared responsibility. It requires governments to implement smarter urban planning, such as creating green spaces that absorb sound and enforcing stricter noise limits. At the same time, it depends on individuals to be more considerate—using vehicle horns only when necessary and respecting quiet hours. Creating quieter, healthier cities is a goal that demands effort from every member of the community.

Many of us install water-saving taps believing we are helping the environment. However, a psychological phenomenon known as the 'rebound effect' can sometimes lead to unexpected results. (37) __________. For instance, a person with a water-saving showerhead might feel they can take longer showers without guilt. (38) __________.

They might think, "Since this showerhead saves water, an extra five minutes won't hurt." (39) __________. This demonstrates that technology alone isn't a magical solution. (40) __________.

A. This change in behavior can cancel out the benefits of the technology

B. To truly conserve resources, our habits and awareness are just as important as the devices we use

C. This effect describes how improvements in efficiency can paradoxically increase overall consumption

D. Consequently, the total amount of water used could end up being the same, or even more than before
