Read the following passage about the The Importance of Social Media in Modern Society 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.

In the 21st century, social media has become a crucial element of everyday life[I]. Platforms such as Facebook, Twitter, Instagram, and TikTok link individuals around the world, [IV]. Although some may critique social media for promoting negativity, it is important to acknowledge its numerous positive effects on society[III]. This essay will delve into the importance of social media, its influence on shaping public perception, and the challenges it poses.[II]

One of the primary benefits of social media is its ability to foster communication and connection. People can maintain relationships with friends and family, regardless of geographical barriers. This aspect is particularly vital for those who live far away from loved ones. For example, a student studying abroad can easily share their experiences with family through posts, photos, and video calls. Furthermore, social media enables individuals to connect with like-minded people and build communities around shared interests or causes. Activist groups, for instance, often use social media platforms to rally support for important issues, raising awareness and mobilizing action more efficiently than traditional methods.

Moreover, social media serves as a powerful tool for information dissemination. News spreads rapidly through these platforms, allowing individuals to stay informed about current events. During emergencies, such as natural disasters, social media can provide crucial information in real time, helping people stay safe and informed. However, this rapid dissemination of information also raises concerns about the accuracy and reliability of the content being shared. Misinformation can spread just as quickly as legitimate news, leading to confusion and mistrust.

Despite the challenges posed by misinformation, social media plays a significant role in shaping public opinion. People often turn to these platforms to voice their opinions and engage in discussions on various topics. For instance, political debates and social movements frequently gain traction through social media, allowing individuals to express their views and influence others. This democratization of discourse can empower marginalized voices and facilitate social change. However, it is crucial to approach online discussions critically, as echo chambers can form, reinforcing existing beliefs rather than encouraging open dialogue.

In conclusion, while social media presents challenges such as misinformation and polarized discussions, its positive contributions to communication, information dissemination, and social activism cannot be overlooked. As society continues to evolve, it is essential to harness the potential of social media while being mindful of its pitfalls. By promoting responsible use and critical thinking, we can maximize the benefits of social media and foster a more connected and informed society.

Read the following passage about education in Nepal 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.

An education pioneer born into rural poverty in Nepal has opened 30 schools in a bid to boost prospects for his country's children.

The World Bank ranks Nepal as the globe's 31st poorest country, with almost 10 million people living on daily incomes between £1.48 and £2.50. Many rural villages remain unreached by government schooling and adult literacy stood at just 60 per cent in 2011.

Surya Karki and his charity United World Schools Nepal (UWS) are tackling high illiteracy and poverty rates by funding and improving education.

The first school opened in 2015 – since then 92 per cent of children have completed primary education, which finishes at age eight, and continued into secondary education with UWS schools. In comparison to 39 per cent of students continuing education who attended government schools.

Mr Karki was born into poverty in rural Nepal. Speaking to the Telegraph he said: “School is the only solution to the poverty cycle that we live in. I was raised by a single mother in a male-dominated society.

“The school that I went to was approximately two hours walk away. My house was on top of a hill and my mother had to drag me across rivers. We used to walk 10 miles a day. The schooling was really bad.”

Of the students who would go to school, he said: “They would end up in the same place, as cheap migrant workers in Qatar, Saudi, or Dubai. There was no value in education – no success stories.”

[A] Karki’s mother was a firm believer in education, and at age eight Karki secured a scholarship to study in the capital, Kathmandu. [B] From there he won scholarships and completed Masters degrees in China and the United States. [C] Karki said. “Inequalities in a country can only be decreased if there is access to knowledge.” [D]

The devastating earthquake in 2015 damaged 9,300 schools, displacing hundreds of thousands of families and pushing 700,000 people into poverty. As of January 2018, only 2,891 schools had been rebuilt. Karki said: “We came at a crucial time, where we could redo or undo what had been done badly. Education was really bad in terms of infrastructure, quality of teachers, training. It was an opportunity for us to really make things better.”

UWS Nepal has so far built 30 schools and has seven more in construction. The schools run between 10 am and 3:30 pm, and have an 86 per cent average attendance rate, which Karki says is almost double the attendance rates for government schools in the vicinity. Sexual health classes are taught to the children in the later years.

The word “undo” in the passage mostly means ______.
