Read the following passage about the Second Acts That Inspire 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.

Life often presents us with unexpected challenges that force us back to the drawing board. Whether due to personal setbacks, career changes, or unforeseen circumstances, the courage to begin again can lead to remarkable transformations. Many inspiring individuals have shown that it's never too late to reinvent oneself and pursue new dreams. Throughout history, countless people have overcome seemingly impossible situations through sheer determination.

[I] Take J.K. Rowling, for instance. Before becoming a literary sensation, she was a struggling single mother living on welfare. [II] Her determination eventually paid off when her books became a global phenomenon, proving that setbacks can become stepping stones to success. [III] This remarkable turnaround demonstrates how resilience and unwavering belief in oneself can overcome seemingly insurmountable obstacles. Despite facing depression and financial hardship, she never gave up on her dreams. [IV]

Colonel Harland Sanders' story is another testament to the power of starting anew. At the age of 65, when most people contemplate retirement, he found himself struggling financially after his restaurant failed. Instead of giving up, he traveled across America, sleeping in his car while pitching his chicken recipe to restaurant owners. His recipe for success wasn't just about the perfect blend of herbs and spices; it was about persistence and determination. After facing over 1,000 rejections, he finally established Kentucky Fried Chicken, which grew into a global empire. His unwavering spirit and dedication inspired generations of entrepreneurs worldwide.

These inspiring stories remind us that failure is not final, but rather a chance to redirect our path. Every setback carries the seed of an equal or greater opportunity, and sometimes the end of one chapter is simply the beginning of a better one. The key lies in having the courage to take that first step, even when the future seems uncertain. As these remarkable individuals have shown, it's never too late to rewrite your story and create a powerful second act. Their journeys teach us that persistence and courage ultimately lead to success.

Read the following passage 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 20 to 27.

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 Our Festival Traditions 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.

Katê Festival

Cultural diversity is a vital aspect of any society, and festivals of ethnic groups play an essential role in preserving the cultural identity of a community. Embracing cultural values through festivals is an important way of staying connected with one community as well as its history and traditions, and a well-known Katê Festival of the Chăm people in Vietnam is an example to prove so.

The Katê Festival, also known as Mbăng Katê, is the biggest yearly festival for the Chăm people in Vietnam. It is a special time of year when they honour important figures in their history and the dead in their families. The Kate Festival takes place on the first day of the seventh month in the Chăm calendar, usually in September or October. It lasts for three days and takes place around three important ancient structures in Ninh Thuận Province: the Po Klaung Yăgrai Tower, the Po Romé Tower and the Po Inû Nagar Temple. All of these places are very important to Champa culture and history.

On the morning of the first day, Cham families take part in processions as they travel to the towers and temple, bringing gifts of fruit, meat and rice. In a special ceremony, the Cham people receive the costumes of the Goddess Po Nagar from the Raglai people, a cultural group with close connections to Champa culture. The Chăm carry the costumes to the temple to celebrate Po Nagar, then they open the gates. Inside the temple, they start bathing the statues of important figures and watching sacred dances. After those performances, people enjoy lively parties until the evening of the festival's second day.

On the last day, people make special offerings to their gods at community houses in their villages and pray for luck and good health for the coming year. Once this is over, there are traditional music performances, and then people do fun activities like playing football and participating in weaving competitions.

In which paragraph does the passage mention activities that take place in villages on the last day of the festival?
