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.
Milu was born in a small village in the north of India, and never had the chance of going to school, because her family needed her to work. So she grew up never having learned to read or write. She was a little sad about it, but she didn't let it upset her too much, and tried to think about other things.
She went through life, never being able to do what she wanted, because she felt that if she couldn't read, then she was somehow less than everybody else. This meant that she didn't make many friends and didn't go out much. She thought people would think she was stupid, and she didn't want them to laugh at her.
When she was fifty-six, she got a job cleaning a school and when she had finished her work, she used to sit and watch the little kids do their lessons. She didn't realise that one of the teachers watched her while she watched the kids, and one day, as she was about to leave, the teacher asked her to sit in the class. The kids thought it was very funny, but the teacher patiently started Milu on her first lesson to learn to read.
That was a few years ago, and now Milu can read and write as well as any of the other kids. She still cleans the school because she likes her job, but she doesn't feel less than everybody else anymore. The teacher, who is now her friend, sometimes gives her a book to read and she learns about people living in other parts of the world.
She has a granddaughter who studies at the same school, and sometimes she helps her with her homework. Being able to do that makes her feel so happy that when she stays alone she has a little cry. When she was in her little village as a child, she would never have dreamt that one day she would be able to help her granddaughter with her homework. She owes gratitude to her teacher friend for the gift she was given.

Read the following passage about powering 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.
TikTok is a popular social media app where people can create and share short videos [I]. It started in China in 2016 as Douyin [II]. The app is known for its easy-to-use tools that let users add music, effects, and filters to their videos [III]. People of all ages enjoy making and watching TikTok videos, which can be funny, educational, or creative [IV].
One of the reasons TikTok is so popular is because of its algorithm, which shows users videos that match their interests. When you open the app, you see a personalized feed called the "For You" page. This page is different for everyone and updates with new videos all the time. Users can also follow their favorite creators to see more of their content.
TikTok has become a platform for trends and challenges. Many users participate in dance challenges, lip-syncing, and other viral activities. These trends can spread quickly, reaching millions of people in a short time. Because of this, TikTok has influenced music charts, fashion, and even language. Songs that go viral on TikTok often become hits on other platforms too.
The app is also a space for education and advocacy. Many creators use TikTok to share knowledge about various topics, such as science, history, cooking, and fitness. Others use the platform to raise awareness about social issues and promote positive change.
In addition to individual creators, many brands and businesses use TikTok for marketing. They create content to engage with their audience, often using popular trends and challenges to promote their products.
However, TikTok has faced some criticism and challenges. Concerns about privacy and data security have led to scrutiny from governments. Despite these issues, TikTok still remains one of the most downloaded apps in the world.
