Read the following passage about the impact of social media on mental health 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 31 to 40.

[I] In recent years, social media platforms have become a central part of daily life, offering users countless ways to connect, share, and communicate. [II] While these platforms offer many advantages, experts have noted rising concerns about their effects on mental health, particularly among young people (Smith & Anderson, 2018). [III] Studies reveal that excessive social media use can contribute to feelings of anxiety, depression, and loneliness, despite its intention to promote connection and social interaction (Twenge & Campbell, 2019). [IV]

A primary reason for these mental health concerns is the tendency for social media users to compare themselves to others. Platforms like Instagram and Facebook often highlight idealized lifestyles, leading users to feel inadequate about their own lives. Additionally, the constant notifications and messages contribute to a "fear of missing out," or FOMO, which keeps individuals in a cycle of checking their phones, often reducing the quality of sleep and overall well-being.

There is also a growing body of research suggesting a link between social media use and decreased attention spans. When users frequently switch between apps and notifications, their ability to focus for extended periods may diminish (Rosen, 2019). This shift in attention can interfere with productivity, especially in academic and professional settings, where sustained focus is essential.

Addressing these challenges requires a multi-faceted approach. Some mental health professionals suggest limiting screen time and setting boundaries, such as "device-free" hours before bedtime. Others recommend engaging in offline activities, like reading or exercising, to reduce dependence on social media and build healthier habits. According to psychologists, such strategies can enhance mental resilience and allow for more meaningful, balanced relationships (Robinson & Smith, 2020).

Thị lẳng lặng theo hắn vào trong nhà, cái nhà vắng teo đứng rúm ró trên mảnh vườn mọc lổn nhổn những bụi cỏ dại. Thị đảo mắt nhìn xung quanh, cái ngực gầy lép nhô lên, nén một tiếng thở dài.

UNEMPLOYMENT IN VIETNAM

    Unemployment is a growing concern in Vietnam, particularly among young graduates. The rapid expansion of the labor market has not kept pace with the increasing number of students completing higher education. According to recent statistics, the youth unemployment rate is nearly 20%, which poses challenges for the economy and society. Many young people struggle to find jobs that match their skills and qualifications.

    Additionally, the COVID-19 pandemic has exacerbated the situation, leading to layoffs and reduced hiring across various sectors. Industries such as tourism and hospitality have been hit hard, with many businesses closing or operating at limited capacity. This has resulted in a significant loss of jobs, especially for those in the informal sector.

    To combat unemployment, the Vietnamese government is implementing various initiatives. These include vocational training programs aimed at equipping young people with practical skills that are in demand in the labor market. Furthermore, the government is encouraging entrepreneurship by providing financial support and resources for start-ups.

    Technology is vital in tackling unemployment issues. Online job portals and social media platforms have become valuable tools for job seekers, allowing them to connect with potential employers more easily. Additionally, remote work opportunities have expanded, enabling individuals to access jobs beyond their local area.

    Despite the challenges, there is hope for the future. As the economy recovers and diversifies, new job opportunities are expected to arise. Continuous investment in education and skill development will be key to reducing unemployment rates in the long term.
