Read the following passage about online dating and mark the letter A, B, C or D on your answer sheet to indicate the best answer to each of the following questions from 23 to 30.

Psychologists have found many advantages and disadvantages to online dating. Among the many criticisms aimed at online dating, the most severe concern is its effects on people's self-esteem and mental health.

Swipe left or right is the main feature of popular dating apps, where users quickly look at profiles. However, this system is criticized for being superficial. A study showed that users often feel less satisfied with their appearance. Jessica Strübel found that after a while, users begin to feel less like unique, special individuals and more like they're disposable. This feeling leads to users becoming increasingly sensitive about their looks and bodies, heightening self-consciousness. Dating apps also added to the idea that there's always something better around the corner, which further pressures users into trying to appear more attractive.

Dating apps not only harm self-esteem but also alter perceptions of relationships. By accelerating the dating process, these apps encourage poor social behavior. For instance, it's not unusual for people to ignore "likes" and messages or to lose interest and cut off communication. This behavior would have been considered extremely rude in the past. But with online dating, it is a common reality.

Furthermore, thirty-five percent of users actually reported feeling pessimistic about dating. Only twenty-eight percent of surveyed users reported feeling hopeful after using a dating site or app.

According to paragraph 2, all of the following are problems with dating apps EXCEPT _____.

Read the following passage about Asia’s culture and mark the letter A, B, C or D on your answer sheet to indicate the best answer to each of the following questions

[I] Chemicals are present everywhere in our environment, some of which occur naturally, while others are the result of human activities. [II]. They are found in the air, water, and soil, and can have both positive and negative impacts on the ecosystem. Some chemicals, like nutrients, help support life by promoting plant growth [III]. However, others, especially synthetic chemicals such as pesticides, fertilizers, and industrial waste, can be harmful to both the environment and human health. [IV]

The widespread use of pesticides and fertilizers in agriculture has been a major cause of chemical pollution. When these chemicals are used improperly or excessively, they can wash into rivers, lakes, and oceans, leading to water pollution. This runoff can also contribute to the depletion of oxygen in water bodies, a process known as eutrophication. Eutrophication harms aquatic life, disrupting ecosystems and causing the death of fish and other organisms that rely on oxygen.

Toxic chemicals such as heavy metals (e.g., mercury and lead) pose additional threats to the environment and human health. These substances can accumulate in the food chain, starting from plants and animals in contaminated areas and eventually reaching humans. Long-term exposure to these chemicals can lead to serious health issues, including neurological disorders, cancer, and other chronic conditions. Many countries have established regulations to limit the use of harmful chemicals, but enforcement remains a challenge.

Efforts to reduce chemical pollution involve a combination of government regulations, technological innovations, and public awareness. Governments worldwide have introduced stricter rules on the use of hazardous chemicals and encouraged the development of eco-friendly alternatives. These regulations aim to limit the harmful impact of chemicals on the environment, encouraging industries to adopt safer practices. Environmental organizations play a vital role in monitoring chemical pollution, raising awareness, and advocating for cleaner technologies. They work closely with policymakers to ensure effective enforcement of environmental laws. While progress has been made, ongoing efforts are needed to address emerging challenges and ensure a safer and healthier environment for future generations.

The phrase "eutrophication" in paragraph II is CLOSEST in meaning to _______.
