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).

Which of the following can be inferred from the passage?

Read the following passage about human life expectancy 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. 

Nomophobia, short for "no-mobile-phone phobia," is a modern phenomenon that affects many people in today's digital age.

What is nomophobia? It is the irrational fear of being without one's mobile phone or being unable to use it. This condition can cause anxiety and distress, and it highlights the profound impact mobile devices have on our lives. The fear of losing or being separated from one's phone is a growing concern. Some common situations that trigger nomophobia include misplacing one's phone, running out of battery, or losing network signal. The fear intensifies when people imagine not having their phones to contact friends and family, access the internet, or use GPS for navigation.

Who easily suffers from nomophobia? Nomophobia is not limited to any age group and can affect individuals of all backgrounds. It often becomes evident when people experience panic or anxiety when they forget their phones at home or are unable to use them temporarily. Symptoms may include restlessness, rapid heartbeat, sweating, and a sense of insecurity.

The roots of nomophobia lie in the convenience and connectedness that mobile phones provide. These devices have become integral to our daily lives, serving as not just communication tools but also cameras, entertainment hubs, personal organizers, and more. This dependence on mobile phones can lead to a feeling of vulnerability when separated from them.
