Traditional Media

Before the invention of newspapers, the main source of news was word of mouth. Any writings and drawings were done by hand. Although printing presses had existed in eastern Asia, it was Gutenberg’s invention in Europe in 1453 that made printing faster and books more accessible. It reduced the cost and size of printed books and made them the first form of mass media affordable to less wealthy people. Gutenberg’s invention also quickened the spread of discoveries and information, and promoted literacy in Europe.

The printing press led to the rise of printed newspapers that appeared regularly. The first newspapers developed from around 1612 and in a short period of time, they became very popular in Europe and the European colonies. In the 19th century, they also appeared in Asia.

Newspapers and magazines are still very popular today. Although most of them have online versions, many people continue to read print media, which is considered more credible than digital media.

In the 1920s, when radio, television, and video were introduced, the phrase “the media” began to be used. Black and white television quickly became popular in the 1950s, and in the 1960s colour broadcasts started in many countries. Thanks to its audiovisual presentation, television became one of the most important forms of mass media in the 20th century. As a source of news, entertainment, and education, it still attracts a large number of viewers today.

Read the following passage about lifelong learning 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] Lifelong learning is the ongoing, voluntary, and self-motivated pursuit of knowledge for personal or professional development (Knowles, 2020). [II] This concept emphasizes that learning does not stop after formal education, but rather continues throughout an individual's life, adapting to changing circumstances and needs. [III] In today’s fast-paced world, where technology and job markets evolve rapidly, lifelong learning has become increasingly essential. [IV]

One of the primary benefits of lifelong learning is its ability to enhance employability. Individuals who engage in continuous education are more likely to keep their skills relevant and competitive in the job market. According to a report by the World Economic Forum (2021), over 50% of employees will need reskilling due to technological advancements in the coming years. Lifelong learners are better equipped to adapt to these changes, making them more attractive candidates for employers.

Moreover, lifelong learning contributes to personal fulfillment and mental well-being. Engaging in new learning experiences can stimulate the brain, foster creativity, and improve cognitive function. Research indicates that individuals who pursue learning opportunities throughout their lives tend to report higher levels of happiness and life satisfaction (Smith & Johnson, 2019). Whether it is taking a course, learning a new language, or picking up a new hobby, the process of acquiring knowledge can be enriching and enjoyable.

In addition, lifelong learning promotes social engagement and community involvement. Participating in educational programs or community workshops can foster connections with others who share similar interests. This social aspect of learning can enhance one's sense of belonging and support networks, which are crucial for mental health (Jones, 2022).

Overall, lifelong learning is not just an individual responsibility; it requires support from educational institutions, employers, and communities to create an environment conducive to continuous education. By fostering a culture of learning, society can better prepare individuals for the challenges of the future and ensure that everyone has the opportunity to thrive.

The phrase "self-motivated pursuit" in paragraph 1 could be best replaced by ____.
